USB Hub Port Connection Information IOCTL / SetupDi

Q: USB Hub Port Connection Information IOCTL / SetupDi

I have a situation where my product enumerates to windows and I can see it and all its sub components.
My problem is that there is a USB Connector - HUB - Port 1 - USB Component

Port 2 - USB Component

Port 3 - USB Component

Port 4 - USB Component
At the time of enumeration the USB Components all the look the same. They have a serial number that is programmed into them at manufacture time, but it is not marked on the part. I can open the device by the serial number. What I need to
do after I open it, is to find out what hub port the device is on so that I can be sure I opened the proper part. If I have the wrong one I can open the next until I get the proper port. How can I tell which port the open handler is on? I
can try IOCTL or SetupDi but I do not know what to look at or what to do with the data when it comes back.
Any ideas?

Ok. So I'm located in a University where the Internet Dorm is behind proxy that disables Internet Applications that involve P2P networking, sometimes Java applications and torrenting.

Ironicly, however, I got to get World of Warcraft going. While this question is game related, its mainly concerning Networking so please keep your eyes on the post.

I got this new game called Warhammer Online, port's blocked and I think I may have found the required port. I'm capable of contacting Help Desk to ask them to unblock this port, but I'm not sure if I wanna tell them that its a game.

So, my question is, can I lie and claim that its a port for some program without them finding out? (Unless they do some research)

I am reasonably OK diagnosing hardware etc but I have never really used a graphics card Display Port as the primary display port on a PC. I have 11 PCs setup in a network at work, all running Windows 7, they all work absolutely fine apart from sometimes when they go to sleep / screen turns off when not in use, I can not get the screen back on!

When this happens the screens etc go off as expected and normally, movement of the mouse or touching the keyboard will 'wake the machines up' however, sometimes the screen doesn't come back on. It remains with a 'No Signal' warning box for all inputs (DVI / HDMI and Display Port). The towers are connected via the Display Port only, anyone come across this before?

I haev another similar setup in another office, using the same / very similar HP machines which have the displayed connected via DVI and have never had the problem with those machines.

Any thoughts, ideas, information, links etc that would be useful would be appreciated before I raise this with our I.T. people (who are not very helpful sometimes, hence why I like to have an bit of an idea of the possible issue before I contact them).

I can find information from people that have asked the questions and had similar problems on other forums, just wondering if anyone had a more technical reason rather than 'it happens' haha.

Thanks in advance.

A:Display Port Questions / Information

I'd look at driver updates for the graphics card(from HP first, then from the GPU manufacturer), a firmware/BIOS update for the graphics card if available from HP if it's an add-in card, or a BIOS update for the system/motherboard.

This isn't really related to windows 7 (although I am using it and doing my programming based on it), I have a simple circuit consisting of a battery, a transistor and an LED.
I want to use the transistor to light up the LED by sending voltage to a cable. I tried using the USB port, however, it has a positive, negative and 2 data cables. Both cables are continuously sending data, so I cannot make the voltage 0 on any of them and stop the LED.
I've heard I must use a printer port, or an ATA connector, I am fairly unsure of what control software has over hardware. Any help is greatly appreciated!
Later edit: I mean other than using an USB interface

A:What port do I use to send information to a piece of hardware?

With a 16 bit OS or even Windows 9x this would be a relatively simple task. But with the NT platform direct access to hardware is the exclusive domain of system level code. Actually it is done by the HAL but that can only be called with system level code, or in other words a device driver. Writing a device driver is not a simple thing.

You really need to find a device driver that can do what you want.

Hello, I am an IT Technician for an electric cooperative. I am having a very odd issue that I can not seem to resolve and I am in need of assistance.

We have 4 Dell Latitude notebooks all running XP and we also have some very high end GPS units made by Trimble that we are going to be using to stake out points on a map. Whenever I connection through bluetooth with the GPS I am able to pair but the GPS control software never recognizes it when I chose the COM port assigned to it. Whenever I connect it directly through a cable(serial to usb) it never detects it either.

However this is the odd part, when I test this on my desktop I am able to connect just fine with the exact same method.

Any ideas?

Do you have another software firewall on your PC? The first thing you could try doing is just disabling the windows firewall and any anti-virus software or other that could be performing connection filtering. That way you could eliminate all possible/known
options. Another thing to consider, if this is Windows 7, there can be multiple firewall profiles. So if your telnet server is on a domain, and you modified the public or private firewall profiles, then that wouldnt work if the network you are currently
on is a domain.
What is the OS of the guest machine and host machine?

You could also consider looking through the event logs on both machines to see if there are any indicators there.

Hi guys, I'm in bit of trouble with my connection right now. I have a Linksys 54G Wireless Router and Westell 6100 modem with Verizon DSL. The downstairs computer recieves connection through a LAN via the modem/router/ethernet and the two upstairs computers recieved a wireless signal. When trying to hook up my Xbox Live account, the IP fails because of trying to connect to BOTH the router and modem. I've researched the problem and found numerous solutions, which haven't worked, probably because I'm configuring something wrong. Anyway, I FINALLY got the Xbox Live IP to work, but the DNS test failed . The exact instructions I got to get the Xbox Live IP to work are found below..... The thing is, now when I followed these instructions, the downstairs computer is NOT connected to the LAN anymore, but rather an PPPOE (WAN Miniport). The two upstairs computers no longer have connection now.

IN A NUT SHELL: I got my Xbox Live IP to be found, the DNS fails (disabling me to play online), but I can only get the Live IP to work when the downstairs computer is connected through PPPOE and the two upstairs don't recieve any signals. When connecting the downstairs back to a LAN connection, it fails to connect to the internet. What I'm trying to ask advice for is... how would I go about setting up all my computers to work AND the Xbox Live to work as well.

A friend recently changed ISPs, from Comcast cable to AT&T DSL. She was sent a 2WIRE 2701HG-B DSL modem/wireless router w/ 4-port switch built-in. She also has a Linksys WRT54G v8 wireless router w/ 4-port switch.

I put the 2WIRE modem into bridged mode so we could continue using the Linksys router for wireless connectivity. I made sure to disable the wireless support in the 2WIRE router.

I had run into a problem where the Linksys router wouldn't reestablish the PPPoE connection automatically if it was lost. A firmware upgrade to version 8.00.5 seems to have addressed that problem BUT now when the router is connected, it's getting a strange subnet mask. It might not be strange but it's completely unexpected.

The IP address is aaa.bbb.ccc.ddd and the subnet mask is The default gateway IP address is aaa.bbb.fff.ggg, so the assigned IP address and the default gateway are on two completely different subnets but in the same class B IP network.

All of the important machines are able to connect to the Internet ok so I'm not sure if the above subnet mask is anything I should be concerned with.

Any comments or ideas?

Thanks in advance!


A:Solved: Question about strange PPPoE connection information

The subnet mask of is a valid mask for a PPPoE connection, it denotes that there is only a single allowed address.

Ok guys, here's my problem...

I was on my pc last night, everything was running fine, i was on msn, the internet and downloading music. I then went to refresh my browser and it came up with "Internet explorer cannot display the web page". At first i thought the router had gone down, but then i noticed that i was still on msn. I decided to click on 'Diagnose connection problems' - It came up with:

"xxx" is not set up to establish a connection on port "World Wide Web service (HTTP)" with this computer.

At this time it was late so i decided to leave it until tomorrow, when i tried it again, internet explorer still wouldn't work,but google chrome did, even though it hadn't the night before, msn is also still working fine.

I have googled this problem and tried the suggestions such as turning my firewall off, this did not help, any other help will be greatly appreciated.

I recently started a thread regarding problems on my Compaq Presario not being able to recognize any USB peripheral on any of the US ports. After trying numerous solutions suggested by HP support as well as this forum, I think most software problems can be ruled out. I was about to take the suggestion of 'DAI' and pop in a PCI USB card.

I have just now discover that my floppy is not recognizing a formatted disk. These floppies are pre-formatted and cna be read in another PC. Can I safely assume this is a different and new problem??? or can this be a hint to what is causing the probelem with the USB ports as well.

A:USB port/Floppy connection?

I would say yes, two different problems...

the USB card is a good idea, would get a 2.0 just for the fun of it, will work with any 1.1 device so no problem there.

On the floppy, I am assuming this drive has been reliable in the past, does not have the light on all the time, and has all the cables and such properly attached. If you have been messing around in the case, sometimes it is easy to knock something loose.

Check it out...if everything is copacetic, maybe time for new floppy.

A:Can I bridge a connection with a USB port?

what you are really saying is

modem---(router)----your system---usb.connected.to.nothing
doesn't show the USB. Of course not put something on the other end

---your system---usb.connected.to.something
However, your system needs the Internet Connection Sharing enabled,
the USB connection on your system needs to have an Ethernet feature,
and the other device needs the same kind of USB/Ethernet device.

The USB slots on your systems will not do networking without using a USB/Ethernet adaptor and installing the drivers.

It is a setting that is in your BIOS that came disabled for some reason.

When your computer reboots and you see the text, you will see the computer running diagnostics on your computer (finding hard drives, verifying memory, etc...). On that first page, you have to press F1, DEL, ESC or some other key to enter your BIOS Settings. Once you enter it, you have to go into Port Management or Integrated Peripherals to enable the SERIAL Port.

If you can determine who made your motherboard, we might be able to determine the exact procedure on how to enable this for you.

To use dynamic address again? Just do what you did before except when you get to the TCP/IP Properties select 'obtain IP auto' and 'obtain DNS auto.' And to be sure it's good to then restart the PC.

If you want help with the Static IP show us the following for what you have now. And then show us what you get after changing back to dynamic (or show for another computer that is working now).

Start, Run, CMD, OK to open a command prompt:

I have a loose eSATA port connection on an HP Pavilion dv7-2043cl. It is a combination eSATA/USB port that can be used either as an eSATA or USB port. When connected, I can wiggle the eSATA cable connection end - there's too much play there. The eSATA connection will intermittently lose and regain contact. I am connecting to a Seagate BlackArmor WS 110 external HDD. When I use the port for a USB connection, it is fine.

I read an old post in this forum about a loose USB port connection, where the solution was to open the laptop and re-solder the port. What I am wondering is, if the same can be done for my problem.

The fact that the USB connection is ok casts some doubt for me. I am not familiar with the physical build/structure of this port and wonder if this combination port is that much more complicated than a USB port and requires more than a simple solder.

I am not adept at nor technically experienced in tinkering with computer hardware and parts, but this appears to be a simple and inexpensive fix ... I hope. The laptop is still under warranty, but short of shipping it to HP, which would probably mean at least a month w/o it, I was hoping that there'd be an easy solution.
Any help on this will be greatly appreciated.

A:How to determine which COM port represent a USB connection?

USB connections do not have com port numbers assigned to them unless its a usb-serial adapter which then it will assign a virtual com port #. Instead they have an address assigned to them. A simple way that I would do it would be if your running windows 7 is to go to devices and printer by clicking start-then click devices and printers. Find the device that you want to lookup. Right click and go to properties. Once at the properties, go to Hardware tab then click properties again. Once there up top you should see General, Driver, and Details. Click on the Details tab and drop the list down till you see Address. That number is the USB number that it's plugged into.

My location does not give me the best WiFi signal so I decided to connect my CAT6 cable instead. The notebook connector is not the typical design with a tough to move door to get the RJ45 connector into. It has lateral movement once in as well as up/down if the cable is moves. Connection can break as well also unless I hold the  cable pushing in only then will it connect at 1GB othewise 100MB only. I can tell the width of the opening is too wide so the cable end can moveand the wire contacts don't have a lot of travel room. The connector has to be right in tight to make a good enough connection.  I have this cable run through my house to my router some cables may be a silight bit different EG A CAT 5 connector. This appears to be a very poor design and all to keep the round curve of the case.  Its the hardest one to use on any notebook I have used and seen. (I have seen a lot over 30 years working with them)

I used the AVG free 2011 tune up program on my PC as my windows xp system was running very slowly. Performance of the PC has improved greatly but I find that I cannot now connect my m1040 olympus camera to the usb port. It is saying unrecognisable device.

Note that I am still able to connect a stick to the usb port and I can also connect my Canon camera and everything works OK.

I can also connect the Olympus camera to the USB port on my Apple computer so the camera must be working.

I do not use Olympus software in the PC but I have always in the past connected the Olympus camera to the USB port, and my computer picked it up as another disk drive.

The problem seems to have arisen after the tune up took place. Any idea what caused the problem and how get my Olympus camera to be recognised.

That's one reason why you should avoid registry cleaner/booster/optimizer/tuneup type programs like the plague. Besides the fact that they do little-to-nothing to improve speed and performance, they tend to break programs and damage the operating system.

When AVG 2011(10.0) was released to replace AVG 9 and decided to add a tuneup feature(which includes a registry cleaner), I stopped using it.

I suggest that you use System Restore to revert your computer back to a date and time prior to when you used it.

I have a new computer and was trying to connect a photo printer. which didn't work. After that I was unable to print anything from my Quickbooks program. I was getting a message that read: There is a problem connecting your currently selected printer HP 5600 series on USB001,you may need to change the port assignment from the windows printer settings or reinstall the printer driver software. I am able to print from my email but not from Quickbooks. I tried changing ports from printer settings but that didn't work. I also tried installing the original software & it wouldn't install. Don't know whatelse to do. Any sugestions would be great.

I'm using Alcatel Speedtouch 530 ADSL Modem and I have ADSL 4096/256 connection. This modem has two options. It can be connected using USB or Ethernet port. I recently upgraded my ADSL Connection from 2048/256 to 4096/256.
My internet provider' s stuff advised me to use its Ethernet for better connection speed. (I believe that it doesn't matter).
So, should I connect it to the Ethernet port or keep it connected to the USB?

A:ADSL connection through Ethernet or USB port?

For one computer connected it doesn't matter. If you later decide to add a router to connect two or more computers, then you need to use ethernet.
