Usb not recognised

Q: Usb not recognised

Hi sir,
I want to tell you that whenever i insert a usb device in my computer a message appears usb not recognised. This problem only appears when i insert my usb in the front ports. I have tried connecting it to the ports at the back of my cpu but then my pc reads the usb. I have tried many things like updating the drivers, uninstalling the usb but still facing the same issue. Please help.

Preferred Solution: Usb not recognised

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


Been having lots of hassle.

Finally got mobo to recognise my soundcard - Audigy 2ZS. Now comp is quite unstable. Keeps crashing of own accord. Sometimes rebooting, other times to completely unresponsive state with display frozen, sometimes to blackscreen and have to hold on button in till machine shuts off.

When I restart I have lost sound. Card not listed in device manager. Computer still crashing randomly.

If I leave the computer turned off for a good couple of hours, sometimes when I restart the sound has returned and card is recognised in devices.

Anybody know what might be happening.

Also, my mouse pointer is jumping all over the screen of it's own accord which is very frustrating. Cordless Optical Mouse, reciever about 5inches away from mouse, latest logitech drivers, worse with SP2, enhanced pointer precission switched off. Mouse mat makes no difference.

Any suggestion on rectifying this prob or is it related to comp crashing ???

A:Soundcard recognised. Crash. Soundcard not recognised. Wait 2Hr Recognised Again ??.


You didnít mention if your sound card is built into the motherboard or is an add-on card. I'll assume itís an add-on. I would check to make sure the sound card is seated firmly in the slot, or another option would be to try another slot. Perhaps the one you have the sound card in is bad. Also, you may want to uninstall the driver for the sound card and download a new one from the manufactureís website.

You also mention that your mouse pointer jumps all over the screen. Usually when this happens to me, it means the battery's are starting to run out and need replaced. Also, try moving the receiver as far away from the monitor, speakers and tower. Interference from any of these devices can play havoc with the signal.

Good Luck.

I recently put some downloaded (freeware) games onto a cd for my kids.
My mum wanted some of the games, so I ran off a copy of the disc for her.

The disc works fine on my pc, but in hers, whether you try to access the cd through "my computer" or through the Start>Run command line, a message comes up saying "the cd is not formatted, format the disc now?"

I wonder if one of these things could be causing the problem:

I have win98se, she has win me (surely that shouldn't make a difference?)

I have a cdrw, she doesn't (but I closed the cd, so it should be accessible to any player)

Perhaps making a copy of the disc has the effect of making a copy of a copy, thus making it of a lower quality?

The original was made using directCD, so I sent the files to the cd on the right click menu. That cd was properly closed as per instructions, to make it useable on any drive.
I made the copy using winonCD, which was bundled with the cdrw, I've used the prog successfully many times.

The cd is maxell, which I have always used, without problems.

Could there be a conflict with using the 2 different programs to make the disc?

Also, winonCD has a delete cd function...I assume I could only use that with a re-writable cd? (probably a stupid question, but if I don't ask, I'll never know for sure!)

This is my first coaster after having the cdrw for just over a year, so I don't want to admit defeat without knowing where I went wrong!!

I wonder if some kind soul can assist ....Recently my computer was taking an age to boot.... repeatedly had to press start. Upon checking the internet I found that a probable cause was linked to power supply....not spinning HD fast enough to boot so I uprated to 500W... and as the computer leads were all out I took the opportunity of putting in an extra 2 Gb RAM (New and checked with Crucial as being compatible)Total 4Gb RAM Install went well.... and boot up took a fraction of the time! The extra RAM was recognised Total 4Gb, initially the Windows theme played.... then...... unable to start - blue screen re Graphics card - started in safe mode... download drivers.... Then graphics OK.... but No Audio - download new driver for Gigabyte MB..... checked Graphics card in Device Manager - Not working Code 32! I thought there must be an issue with the graphics card so I purchased and installed another. I also removed the extra 2Gb of RAM. I performed a clean install of Windows 7.... Graphics card working and drivers downloaded.... Brilliant ! Then I re installed the 2Gb RAM.... switched on nothing but a long beeeeeep foloowed by another.... followed by another .... I turned off the power, removed the 2Gb RAM and the computer booted fine!
So I can deduce that the graphics card works OK (the old one probably did too!) and the 4Gb RAM is OK.... just that the 4Gb of RAM and the Graphics card do not like to work together

I recently was given a new 512mb DDR400 RAM by a friend who stupidly didn't actually check whether it was compatible. I have added it to my own 512mb DDR400 in my Gigabyte motherboard. Individually, both work fine, however when they are both in, the computer still only acknowledges 512mb. I upgraded my BIOS, but that hasn't fixed the problem.

Can anyone offer any suggestions for stupid things I have done wrong? Should I have any options involving RAM in the BIOS, because I can't find any.

Thanks in advance.

Edit: I should add that I tried the various different positions and orders of inserting the RAM, which did not make a difference.

Last month I bought a brand new Fujitsu computer for christmas (Windows 7 64bit), when I got it set up it worked perfectly until I got a message saying that it was out of disk space, so I went to my computer and checked if it was full. Sure enough it said 1.4gb free, but what shocked me was to find it said I only had 40gb of disk space! On the box it said 500gb, when I googled the HDD it was only available in 500gb (ST3500413AS). I went to BIOS and it showed this;
Serial ATA Port 0-----ST3500413AS

Hello to you all

I have a computer with 2 S-ata Mobile Racks.

As a request of a friend I disconected the Racks and I putted a IDE Drive to format it. After I have finished I connected back my drives but both are not recognised by the Bios. It recognises only the CD-ROMs.

I tried to connect the drives directly not with the help of my racks, but no results either.

I suspect that my S-ata controller is burned.
How can I verify this controller?

Any suggestions ?

I have 2 ssd Samsung SSD 840 pro series (c and Samsung SSD 850 EVO 1TB (d.

Both these drives are recognised I presume correctly.

They are installed on a Toshiba QOSMIO X500 PQX33E-00N006EN laptop.

Trim is enabled as I run fsutil behavior query DisableDeleteNotify in command prompt with result 0.

I cannot defrag using trim any of the drives as you can see from the below

I did not have this problem in Windows 7.

Any help in solving this would be appreciated.

Thank you.

A:ssd not recognised

I might not be reading this right, but but the command window is saying (correctly) that the SSD drive cannot be defragged (actually it should never be defragged). It is performing the trim function as it should. In Windows 10 there is an optimize function which will send a trim instruction to SSD's and defrag traditional hard drives. Both actions are performed under the same heading of "Optimize Drives".

I'm trying to upgrade my RAM
I have a PC clone with Intel Celeron Processor about 3 years old which came with
1 x PC100 32MB RAM stick
1 x PC133 64MB RAM stick
which worked fine but after a recent hard drive crash and replacing the crashed 10GB with a new 20GB I found the system was still struggling memory-wise so I deceided to upgrade RAM.

Now I've bought a Kingston PC133 128MB SDRAM (KVR133X64C3/128)
and taken out the 32MB and put the new 128MB stick instead, thinking I'd get 128+64=192MB
but when I started up the system I find it's only quoting 128MB and ignoring the 64. I swapped the two sticks around in the two slots and same result.

What am I doing wrong, and how would I find out if my system is not actually upgradeable to the amt of RAM I'm trying to use?

I live in Papua New Guinea and the company I bought the computer from is one of these uppity types that want to charge you an arm and a leg per 15 minutes for asking these kinds of questions.

Just got system mechanic and am defragmenting my drives. I have 2 SSD's and 1 of them is my main system drive and the other is for gaming. The gaming SSD is recognised as a normal HDD and not an SSD, whereas the system SSD is recognised no problem. System Mechanic uses different defragmenters for HDD's and SSD's so I'd rather the gaming SSD was recognised correctly.

I'm using W7 64 and my motherboard is a gigabyte 990fxa-ud3.

Any ideas how I can resolve this?


A:SSD recognised as HDD

Hi, you should not defrag a ssd drive. Indeed MS will disable auto defrag when an ssd drive is recognised. Defrag will not improve an ssd's performance, it will seriously degrade it.

System Mechanic will not improve your computers performance, it is not a recommended util, you should do yourself a favour and be rid of it, the claims they make about the product are simply not true.

Since windows seven MS has included "Trim" built in to optimize ssd performance, this is all you need.

Hi I hope someone can help,

I have a Windows XP SP2 desktop, Pentium 4 CPU 2.6GHz, 513 MB of RAM, and it fails to recognise CDs in the DVD rom when I want to copy music onto a re-writeable CD. All my music is legit, bought by me, and I only want to copy it for my own personal use (i.e. take it in the car). The DVD-rom recognises DVDs and most shop-bought CDs, although occassionally I do have a problem getting it to (it seems really unpredictable).

It thinks for a while and then comes up a blank 'no cd in the drive'. I only have one drive which is a DVD-rom.

Surely it can't be simply that it's a DVD drive instead of a CD drive? Because that would be very annoying. Or is this a hardware problem, i.e. do I need to get it replaced?

Many thanks

If it is really old it may not recognize burned cd's or it actually is a separate function and either needs cleaning or replacement. They aren't the most reliable hardware and are not expensive either.

So this is annoying, the ONLY thing I had done was switch out my SATA cables with some new ones, mind you they are exactly the same SATA cables as my old ones, just different colours.
NOW my OS doesn't exist apparently; my other hard drives (slave drives) are shown but not my OS SSD for some reason.
Any clue what I did wrong or what I can do to fix this? It must've been something really stupid on my part.
Does anyone have any idea on what just happened? Thanks in advance..


1. I just replace my SATA cables with the new ones, the only difference being the colour.
2. I figured the SATA cable my OS SSD was using was a faulty one, replaced it with another SATA cable I had.
3. I figured the other hard drives connected were confusing my motherboard because it's stupid. So I disconnected all the hard drives except my SSD (OS).
4. I figured the SATA slot I was using on the motherboard was a faulty slot, so I slotted it into another slot.

Hi, I've always had problems with my dvd burner. I'm not sure if it is my computer, or problems with Nero. The dvd's I am using are compatible with my Sony dvd burner. If I insert I dvd and then open 'My Computer' and click on the dvd drive, there is no dvd recognised. I have Nero 6, with all the latest updates, and that seems to recognise the dvd. However, only about 10% of burns work, with the rest leaving an error message and the dvd corrupt (expensive)! The error message that is left is below, and the logfile is also attached. I am trying to burn simple video files, and I know it sometimes works. Out of interest should it be possible to simply burn photos/videos onto dvd simply by opening the relevant dvd drive and copying the files into it? I run Windows XP home with service pack 2.

I have an Imedia MC2559 with a Gigabyte GA-8TRC410MNF-RH Motherboard.

I am trying to add more RAM, the support pages say that it will take up to 4GB with maximium speed of 667mhz in the two slots; I currently have 1.5GB of PC2 4200.

I recently replaced one stick with a PNY 2GB PC5300, 667mhz module; my PC failed to Boot, it went to a Blue screen with an error message. I tried the new RAM on its own and it worked fine so assumed it was the different Bus speed that was affecting it, though I thought you could mix speeds and the lower one would be used?

I then borrowed 1GB RAM with the same specification and tried it with the 2GB, the system booted OK but the BIOS and XP Performance graph only showed 2GB?

I am completely flummoxed as to what's going on, can anyone please help?

Incidentally when I did a Crucial system it only shows 1GB available not 2?

A:New RAM not recognised?

Make sure the BIOS memory setting is set to SPD,so the
computer can read settings from the memory chip.
Then try it with the slower memory in the first slots
and the faster memory in the last slots.
Also make sure you are not trying to use high density and low density
memory together.
Some motherboards can't handle high density memory well.

I have an Epson R300 printer. The expensive Epson inks are no trouble but I have recently bought some compatable inks (£9 for 6 instead of £49 for 6 !) Error message told me ink cartridge not recognised. Compatable ink supplier suggested I uninstall printer software and reinstall from original CD. This worked ( a few weeks ago) but will no longer. Can somebody help please. Thanks. Windows XP by the way.

I have a acer aspire 5315 notebook, running windows vista home basic.. i decided to reboot it, during this it froze. everything went corrupt. i purchased spotmau powersuite professional 2008 (spotmau.com) this allows you to speed up your computer , format , partion HDD's etc etc. this allows me to see my hitatchi 80.00 GB HDD but when i try to load it in bios it goes to a black screen and in the top left corner with a underscore line that continues to flash. i have been told this is where the computer cannot find the HDD. if i run a windows disc to install windows it gets to a point where it cant find my hardrive to save windows to. does anyone know how to format or do something that will enable my hardrive to be able for usage ? ( my hardrive has been completly wiped so its now blank and has been formatted to NTFS, yet it cant be recognised in bios)
Many Thanks

A:HDD Is Not Recognised?

The hard drive may be bad. Get a USB external enclosure and try formatting it on another system. If it can't be seen, you have a bad drive or the master boot record is destroyed

Recently my laptop stopped recognising my iomega 1TB ex hd. I can see it in device manager, but not in Computer. Any attempts at data retrieval have been unsucessful - either the data retrieval program cannot 'see' the ex hd, or it takes a ridiculously long time to scan (even a small part of) it. I think the issue may be related to it not having been formatted before use, though I was able to save to it (and subsequently access those files until recently). I do not believe that it is a mechanical problem (there is no clicking noise), though (further to researching my problem on the 'net - to this point with no solution) I do not have the expertise to know what to do next. I suspect that there MAY be a straightforward solution to my problem, and I am trying to avoid sending the hd to a expensive specialist data retieval lab if I can avoid it. I can post any further information that might be required; I'm just not sure what kind of info might be relevant. I would GREATLY appreciate any help you or your members might give me. Thanks.

Hi there, I need some help please, I'm getting a popup about every 10 seconds, saying "usb device not recognised" even though all my usb devices are working properly, is there any way that I can disable this popup or fix the root of the problem, i've tried system restore and even formatted the hdd once,I'm running XP sp2.

A:USB not recognised pop-up

If you re-installed XP fresh and still get the errors, my guess is either the USB controllers or one of the USB devices is causing the issue. Did you try disconnecting USB devices a couple at a time and see if you can make the error stop?

I've been running an Abit Hot Rod 100 Pro with an IBM 75GXP 15GB HDD for a while now with no problems. Finally got round to getting a second HDD, same as the other one, so I can get some RAID action going, specifically a stripe set.

The problem is I can't get the new HDD to work.

I've tried plugging it into the second IDE chanel on the 100 Pro card and booting with every possible jumper setting but the disk is never detected.
I've tried plugging it into the Mobo IDE but with the same results
I've tried simply unplugging the existing HDD and putting the same plugs into the new one but again it's not detected.

Is there something I don't know about installing a new HDD or is it shafted?

Any ideas?

Here's my spec.
Win98 / Abit KA7(TY Bios) / Athlon [email protected] / GeForce256 DDR / Creative Live 1024 / PCI Fast Ethernet Adapter / Creative CDRW / IBM 75GXP HDD on Abit Hot Rod 100 Pro / 300W PSU

A:HDD not recognised

You have to make a partition on the drive for it to be recognized. Go to a dos prompt and type fdisk. From there is a menu and I believe #5 let's you switch from one hard drive to another. If it's the main hard drive you want #1, not #5, if it's the secondary one then choose #5 then the 2nd hard drive, and make the dos partition there.

Looking back through all my disks it seems I have always inadvertently always used dvd- or cd-. Whats the difference betwenn the + and - disks and why can't wy drive read them. SIW says it should be able to see them.

Any advice appreciated

Misco.co.uk - What is the difference between DVD-R/RW, DVD+R/RW

What's the Difference between DVD+R, DVD-R, DVD-RW, DVD+RW, and DVD-RAM? :: Online Tech Support Help :: Ask Dave Taylor!?

The DVD-R DVD+R difference can easily be summarized by the following: The DVD-R/RW standard was developed by Pioneer, and is used primarily by Apple and Pioneer. These “minus“ discs can only be written to in one layer on the discs surface. In addition, this format is supported by the DVD forum, but is in no way an industry standard. DVD-R/RW discs are cheaper than the “plus” format.
The DVD+R/RW format is supported by Philips, Dell, Sony, HP, and Microsoft. These discs can be written to in multiple layers, giving them slightly better and more disc storage than the “minus“ format. Because of this additional capacity, they are slightly more expensive than “minus“ discs.

i am dealing with a very strange problem right now.

first of all, my system specs:
PT6 SE Mainboard
Intel Core I7 920
12 GB ram (6 x 2GB DDR3)
Nvidia GTX 260
Windows 7 Ultimate 64 bit

Recently windows 7 only shows me 8 of 12 GB Ram, when I check with CPUID it shows me all 12 GB ram. The bios shows me 8 as well.
what is wrong and how can I fix this? I thought of the mainboard or the chips being bad but if that would be the case CPUID woudnt show me all 12 GB RAM.
