Need help in identifying and drivers for USB Serial Adapter

Q: Need help in identifying and drivers for USB Serial Adapter

Hi, i was wondering if you all can help me with this issue, I bought this adapter from the store, and found that it didnt include the driver CD. I couldn't identify it as it didnt have the company name / brand on it. I tried searching the forum and found someone with similar issue as me. I've tried the solution that worked for him, but Windows XP doesnt recognize it. So I hope to find help in solving the issue.

Thanks in advance
My device ID is USB\VID_5372&PID_2303\5&32FC3193&0&2

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.)

I have come into a Compaq computer with a bad processor. I am trying to identify this exact computer by serial number only as there are no markings other than "Compaq Presario" and the serial number.

The computer is in perfect cosmetic condition and all markings appear to be present. It appears there was never any model number markings on the front or sides and if there ever was a model number sticker on the back, it was removed without leaving even a trace it was ever there.

There is, however, an excellent, clear serial number sticker; but, I can detect no way of looking for support at the Compaq site by serial number. Does anyone here know of a way?

I have a Toshiba Tecra M11-17V laptop, which I frequently use with the docking station that came with it.
There is a DB9 serial port on the back of the docking station but I do not know what COM Port it is.

I am using Windows 7.

In Device Manager, COM9 - COM22 are identified as BT Port (bluetooth). COM7 - COM8 are RIM Virtual Serial Port v2, COM17 is Prolific USB-to-Serial Comm Port and COM18 is USB-Serial CH340.

I figured that COM17 or COM18 were the most likely candidates, but have not been able to get it to respond using either of them.

I am connecting a Psion 5 (Comms app) to it, and have set the ports and the Psion to 19200 baud, 8bits, 1 stop bit, no parity.

A:Tecra M11-17V - Identifying the serial port on the docking station


> There is a DB9 serial port on the back of the docking station but I do not know what COM Port it is

I think you misunderstood something wrong?
The COM ports available in device manager are ?virtual com ports?
There is no connection between an virtual com port and serial port.

I?ve got one question: what docking station do you have exactly?

I had an express port replicator and this device required an installation of additional serial port driver.

Hey. I lost the tip for my universal adapter, so my computer won't turn on. The tag with the serial number etc is scratched up. I'm almost certain the product number is L3C51UAIAPI though I'm unsure about the second A... Either way, searching that returns nothing.All I can find out is that the battery has a tag that saysCT 6DXZR06WY7XD3Jit has another number 746641 001 which let me identify what the battery is but I don't know if this battery is used for multiple laptops or not.Battery says it's 11.1V but I remember the charger being 18.5 or 19.5 V so that's no help.All my work is on my computer and I've already lost one of my jobs due to being unable to access it so any help is much appreciated.

My WinXP Home Edition keeps on freezing, just when I least want it to. I've gotten the Microsoft page that says this problem was caused by a driver. It list a few different ways to troubleshoot problem drivers, among them System Restore, which really doesn't tell you what the problem was, and anyway, all my system restore points older than a couple of days ago are no good anyway (was not able to complete the System Restore process). They also suggested repairing WinXP by booting from the CD. This also doesn't seem to address the problem of actually finding the culprit driver. Furthermore, my computer froze again halfway through the process. I don't remember updating or installing any new drivers for a long time, so my memory is no help. I've also gone to Programs\Accessories\System Tools\System Information, and looked under Problem Devices, but it doesn't list any. Is there not some diagnostic program that can scan your system for problem drivers? I can't believe there isn't some built in way to do this in WinXP. I'm told that Macs can do this easily. This is very frustrating and unacceptable. Can anyone give me some pointers here?

So I'll need to get some kind of adapter/converter to connect my monitor to my laptop. I've never dealt with this situation before and I wanted to get some opinions about what kind of product would be my best choice.

Truthfully, depending on what you need the serial port for, none of them may work properly. You might consider a PCMCIA serial adapter, which will probably be more compatible.

Why many drivers in vista should be installed manually( by addressing Driver Store in system 32)?Although many of them are installed automatically in XP?

A:Poor Vista In Identifying Drivers

Vista is much more capable in identifying drivers than XP was, and even will go out on the web to locate them if you let it. The built in driver store is also much larger than it was in XP, making more drivers available.

But, it's impossible to include every driver in the distribution package. There's just too many of them, and not all of them are known to Microsoft.

I'm a new guy in this forum and I hope someone can help me.

I've recently bought a laptop with windows 7 home premium 64 bits. I've tried to use a usb/serial adapter (Lindy rs232) but everytime I start the software I need (Vemco's VUE) the computer shuts down. I've tried updating the driver for the usb/serial adapter and also use different usb ports. So far nothing worked. If I connect the usb/serial adapter and check the com ports everything seems to be working fine. When I start the software (Vemco's VUE) it works properly until I connect the usb/serial adapter.

I used the same setting (software and adapter) in an older laptop running XP and everything worked great.

Any advices?

I am helping connect a GPs to a laptop for some yachties. The problem is that when we connect the GPS (via the serial to USB adapter) to the laptop, the OS thinks it sees not only the adapter but also a "Microsoft Serial Ballpoint Pointing Device." It then loads the driver for that phantom device and starts interpreting the incoming GPS data as mouse coordinates and clicks, causing the cursor to go crazy. Only by turning off the GPS and then uninstalling the driver for the 'Serial Ballpoint Pointing" device can we avoid all of this and get the GPS talking nicely to the navigation app. So, how can we prevent the OS from automatically "seeing" this phantom serial ballpoint device and loading the driver? (If we simply disable the device it intereres with the COM port and the navigation program cannot see the GPS.) We need to keep the serial ballpoint device driver from loading at all.

I'm looking for some help and advise on my USB to serial adapter. I have a new connector bought from FRY's and I figured it would be a simple automatic install; wrong. I plan on using this adapter to connect my wideband Air Fuel Monitor in my Mustang to datalog along with my other functions on a program called Binary Editor on a device called Tweecer.

The USB to Serial adapter is recognized by my computer and goes thru the initial automatic install and I let it search automatically for drivers; well none were found. I'm assuming I need to install the driver manually and that creates another problem. I'm not sure what USB to Serial adapter I have. The only marking on it are "Made in China"; no help. When I try to open the Air Fuel Monitor program it says there are no comm ports recognized or turned on.

So I'm here looking for help before I go out and buy another adapter.

A:USB to serial adapter problems

You don't need to install drivers for the adapter. You need to install the drivers for the hardware that you are connecting ( Air Fuel Monitor ).

Hi all,

At work, we have recently got some new software (MARS) to run our CNC machines. The software came with a 'Hardlock Key' which plugs into a parallel port, MARS will only open when this 'key' is inserted into the parallel port.

The cable coming from the CNC machine connects to a serial port, so we have bought a USB Serial Parallel adapter (Prolific PL2303 or something along them lines). The problem we are having is that MARS will not run when the 'Key' is inserted into the USB Serial Parallel, and the error message 'Hardlock not found' is shown. The USB Serial Parallel is under COM3 (can be changed) and MARS will not run, However when the 'key' is directly plugged into the parallel port on the back of the computer MARS will open and run correctly.

If anyone has any ideas on how to get everything working, it would be greatly appreciated!

(Sorry im not very tech savvy, so if you have any questions i will try my hardest to answer!)

So this computer has been having this problem for a while.
The computer has some equipment connected via a usb to serial converter and it just sits there always plugged in having no problems. However when we go and open up the software which actually tries to pull data from the device, bam, bsod (not all the times, but most of them).

Searching on the internet suggests the usb to serial adapter was a bit dodgy (made by ATEN), so I bought a better (more expensive) version from a different company(keyspan usa-19hs). Yet we still have the problem.

Hopefully someone can lend a hand as to what the problem is now.
I've used DM Log Collector and attached the results.

Thanks again seven forums!

(Im 90% sure its the adapter, but i might be wrong! Something else could be causing the bsods!)

port selection isn't there for the serial adapter. But if I plot to my local usb printer it does which is only letter size. How do I find this port? I also have it installed in win7 and it shows up as com 4 in device manager. In XP it doesn't show up as a
com port
But there are two Virtual usb drivers. After much reading I understand there re only two usb ports in Virtual mode, I assume that is why my device manager shows two Virtual usb drivers. Any way is there a way to get my plotter connected?

If I conect the adapter before I boot up the PC it crashes with a blue screen. If I boot up without the adapter conected all is fine.

I know the simple fix is to unplug the adapter before I boot up - but you wouldn't believe how many times I forget.

Does any one have any ideas on fixes for this problem? I have checked the Belkin site for newer drivers but they are all older than the ones that came with the adapter.

For what it's worth - windows gives a message about the driver not being certified when I install it ( and the install instructions say to just ignore this and keep going).

First of all, Hi everyone, I'm new here!

I need help with a serial communication problem between an external device (G-Tech PRO RR accelerometer datalogger) and my personal laptop (Toshiba Satellite A200-MR4).

My laptop doesn't have a serial port. So, I bought a HL-340 USB-Serial adapter. I'm using Windows Vista 32-bits. The installation of the driver and the adapter is fairly easy and Vista recognize it as a new COM port like it should.

I can even have echo when I'm doing a loopback test (bridge pins 2-3 on the serial male connector and using HyperTerminal).

But, I cannot communicate with the external device.

The external device and the USB-Serial adapter are working wonderfully on my desktop PC using Windows XP. I can download data from the external device without any problem using this desktop PC and XP (using the USB-Serial adapter too).

So, the big question : Why I can't communicate with the external device if I can have echo with a loopback test?

Let me know if you have any ideas!



A:USB-Serial adapter and Vista, no communication...

Sometimes USB can be funny.

Try to delete the driver and reboot.

Then install the driver berfore the introduction of the device.
It may ask you to insert the device at some point and that is fine.
It is just that on occasion the driver needs to come before the device in order to work correctly.

You may also need to install the driver by right clicking and "Run as Administrator"

If this isnt a help possibly look into the BIOS setup and ensure that
"Legacy USB" is enabled and try again.

If all else fails it may be necessary to install in compatibility more and select XP

I am trying to fix a PC that had a replacement mobo fitted (by me). I boot into Vista and it part loads numerous drivers before settling down and letting me do whatever I want, although the driver installation does request a restart to complete some driver installs. But if I restart the PC I get a BSOD with stop code 7b. I am then not able to start even in safe mode. I tried a repair install but am back to the same situation. Fortunately, I took an image of the disk before I did anything so I can get back to being able to boot once.

I understand that 7b indicates a problem with the HDD, but I have run a manufacturer's diagnostic, CHKDSK and virus scan and not found any fault. Vista's automated repair is not able to help (beyond telling me that a driver is bad). If I could identify which driver is causing problems I could just disable it from starting by loading the system hive from C:\Windows\System32\Config\System and (please correct me if I'm wrong) changing ControlSet001\Services\????\Start to 4

But how to identify which driver is causing me grief ? I saved a log file of an abortive start by booting off the installation DVD then from recovery command prompt editing C:\Windows\INF\setupapi.app.log and I will attach that file here. It contains several failures, but how do I identify the particular driver that is causing my BSOD ?

I am frustrated. My wife has a Pfaff 2140 embroidery m/c. She has bought a new Laptop which does not have a serial port. So I got a generic Adapter Serial to Usb. The m/c has PC Communication card with a 9 pin serial. I have loaded the drivers for a Prolific Adapter. Then I closed down and restarted with the M/c connected to the laptop using the Usb. No communication was the message I received. I have determined that the port on the laptop used by the Laptop driver is com(7). I do not know which port the m/c wants. Although someone my wife spoke to says the m/c wants com(4).
How can I achieve the connection between Laptop and m/c? Please make me happy.

I've seen this with parallel/usb adapters.
Use the USB port.

Hello all,

Much thanks for the help; really appreciated.
And for your time on this.

I am running an HP Desktop Pavillion, about 3-4 yrs old, and W7, the 64 bit version.

My problem relates to trying to get my Keyspan/Triplite USA-19HS USB To Serial Adapter working again.

I haven't used it for about a year, and am now trying to get it going again.

Have Downloaded what I am pretty sure is the correct Driver/installation package from their site.
Seems to install just fine, and the Keyspan Folder is under Programs (x86) where I imagine it should be.

Also, two of the actual Drivers, and two of the .dll also ended up in the System32 Folder.
Don't understand this, but I imagine it is correct.

Have Downloaded and re-installed, now, several times, bith with and without the actual unit on the end of the cable.

No matter what I do, in Device Manager the Keyspan icon does show, but has the yellow "not-good"
mark also. Error msg when I click on it is that it cannot find, or open, the unit.
Also, essentially the same message appears in their "Assistant" program to the effect that it cannot locate the unit (even if it is plugged into the cable).

Have spoken to two of the Keyspan technical support guys. Really nice, helpful, and apparently really
know the product, but haven't been able to offer anything much more than the re-tries.
The green LED on the unit never goes on.


Since it seems like it is probably something I am doing wrong, as usual, (will blame ... Read more

The driver on there website should be more then essential.

What might be the issue, is if your system is 64 bit it might not support that and maybe only work in 32 bit machines. I noticed this is not the issue, website says it can be on 64 bit

You can also try "device manager">"ports"> and click on the properties of the new device and change it from com3 to com1 for it to work properly.

If the light does not come on, maybe its dead and the unit failed. Looks like it would still probably be covered by warranty.

Hopefully that might help.

I have 2 different adapters and neither one will work on my new computer with windows 8. Any fixes? Are there any adapters available that will work on windows 8?

A:USB to serial port adapter not working on Windows 8

Welcome to Tech Support Guy

What is the serial device you are trying to connect
What is the make of the USB to serial adapter

The problem is that the processor chip - YES they do have one, is not in many cases compatible with Windows 8, especially 64 bit, as of course the actual working of the adapter is achieved by connection to the USB port and then transmission of data from and to the USB hub.

Not knowing what you actually wish to connect your best first port of call is here to see what is on offer

scroll down for USB to serial or click USB on menu at top

I'm trying to connect to some legacy equipment with a USB to serial adapter. The adapter is showing up under the USB menu in the virtual machine, however, when I try to select "attach" it comes up with an error that reads "Could not attach
the USB device. You can attach the USB device to a different USB port or restart the virtual machine and try again.". I've tried both restarting the virtual machine and plugging into a different port, either way, it will not accept the adapter. If it
helps I have two adapters, a Black Box 724-746-5500 and a TRENDnet TU-S9, configured to comports 3 and 8 respectively. I'm getting the same problem with both of them.

I'm thinking of getting myself some retro hardware with serial connections on them. This is as opposed to getting PS/2 because PS/2 can slip off easily, whereas serial connections can be screwed together. I've done the research and know that USB to serial adapters can solve this. However, I narrowly missed what could have been a major faux pas insofar as my competence as a computer engineer is concerned. Can I plug a serial peripheral originally intended for a Mac into a PC via a USB to serial adapter and it will function (assume the buttons are remappable)? The logic side of me says yes because a serial connector is similar to an RJ-45 connector in that the pins are predetermined by some industry standard to work in a specific way across all platforms and it's just the application of said product that will determine how it will function. However, I, also, know that American cars require American socket sets to be able to tinker, adjust, or repair said car.

Feel free to throw in any advice insofar as PS/2 peripherals are concerned as well. I may not care for that interface. But, I welcome the information.
