Over on MyItForum. I rewrote it in PowerShell and was pretty happy with the results so I thought I would share them. Let me illustrate:. Clear as mud right? These are WMI Path names and are not so readable. Below is the VBScript that I got from here. Echo objUSBDevice. So that means that you can replace this script with the following one-liner Note: I decided to sort and things to make it prettier [and to show off J ].
In the past, people have thrown rocks at WMI for being difficult and obtuse. There is a ton of great information in WMI and now with PowerShell, you have a tool that makes it easy to find and manipulate. Log in to join the discussion. PowerShell Documentation.

Failures are usually caused by buggy applications or broken hardware cameras, USB cables and USB host controllers can be faulty. You should start with trying several applications.
In particular be careful that different webcams might use different video formats, and some of them can be unsupported in some applications. If all applications fail display the same failure, chances are that your hardware is broken or at least buggyor that you're lucky enough to have hit a bug in the UVC driver.
To diagnose the problem, please follow this procedure:. When querying devices for their supported frame rate, MPlayer exits with the following message in its log:. Older MPlayer version had trouble detecting video frame rates for digital video devices such as webcams.
The problem has been fixed in MPlayer 1. In the meantime, you can override the frame rate with:. Beside the obvious reason of false advertising, the actual frame rate depends on exposure time. The longer the webcam exposes a frame, the lower the frame rate will be. If auto-exposure is turned on and the environment is too dark, the webcam can automatically raise the exposure time and thus lower the frame rate.
You can disable auto-exposure and control the exposure time manually through the 'Exposure, Auto' and 'Exposure Absolute ' controls. If your webcam application doesn't offer a way to access those controls, you can use a panel application such as qv4l2 or a command line application such as yavta to control exposure. Starting at kernel v2.
UVC devices that are not in use will be suspended after a delay to save energy this should not be confused with system suspend, where the whole system is suspended. This results in several different symptoms, such as large stream start delays or corrupted video streams. The audio interface of the webcam can also be affected. Starting at kernel v3. If you think your system is affected by the problem, you should update to a v3.
Not all UVC devices are bug-free.

To be fair, most UVC devices are buggy, and some of them are so broken that they will not work with the uvcvideo driver out of the box. They should not have been labelled as UVC-compliant or even been sold, but the harm is done and we need to find a way to cope with it.
That's why quirks have been introduced. When a quasi-UVC device exhibits a UVC non-compliance either because its developers have interpreted the UVC specification incorrectly, or because they forgot to implement parts of the specification that are not used by the Windows driverthe uvcvideo driver needs to handle that device in a special way.
The driver tries to do detect those cases automatically, but needs to be explictly instructed on some cases. Each of those special cases is called a quirk and is identified by a flag. Supported quirks are. Try to set this quirk if the device stalls the minimum and maximum video probe and comit requests.
Try to set this quirk if the device stalls the set video probe and commit requests. Some versions of those cameras advertise UVC compatibility but use proprietary video data encapsulation that needs to be handled specifically.
UVC devices are required to toggle the FID bit at every frame, and the uvcvideo driver uses it by default to detect the start of a new frame. Try to set this quirk if the driver doesn't return any frame to applications after successfully starting the video stream.Linux users can, of course, just use lsusb or usbview.
If you are already root, you can just run lsusb without the sudo. Compare the listings; the device which disappears and then reappears from the listing is the device you want. If you use lsusb -v without this, you get the long form listing for all devices which can be very long indeed and include a lot of irrelevant information.
If you are using a Knoppix or Ubunto Live CD, you need a way to share this information with the outside world. You can run the firefox web browser if your network adapter is working and paste the information into a web form if that is all you need.
Or you can save the info on a usb flash drive or to a windows hard disk partition. If you create a USB flash drive to boot Knoppix or ubunto directions on the netcreate a small FAT32 partition on the flash drive so windows can easily see it. Usbview is a GUI application. It does not provide as much detail as lsusb -v but it provides it in a nice tree format. Incidently, usbview also give you hints as to whether your device is plugged into a slow USB full speed port or a fast USB 2.
It is more detailed than a plain lsusb and more succinct than a lsusb -v. You have to pick the approprate block of information separated by blank lines from the output.
This is the form that it submitted to www. Leading zeros are supressed rather than printing as 4 digit hex. To use, unplug the device. The tail program with these options will just show you the new information as it is added to the file. Here is some sample output: Apr 15 cervantes kernel: [ We provided a brief description of the task and they simply did the job!
Anatoly, Digiweb.Each Logic analyzer contains USB device identification information. If the memory that holds that information fails, the device will start to enumerate as a Cypress development kit with the default Cypress VID and PID for that part. Original Logic. Logic 4. Logic 8. Logic Pro 8. Logic Pro On Windows, open Device Manager and locate the device. Open the device properties and navigate to the details tab. Select "Hardware Ids" from the Property list. On Linux, you can run lsusb. Make sure you have selected the Logic device.
You may want to remove it and reconnect it to verify that the entry correctly disappears and then comes back. If your device no longer identifies properly, please contact support about a replacement.

What is a good way to look up the vendor of the device using this information? My motivation is that I want to deploy an application to my users that will identify all USB devices connected to their systems. It's just one of those things you have to keep an updated list on, although having slightly outdated information wouldn't be terrible, since the most popular vendors have been around forever.
Here's one source you could use that appears to be regularly updated. Try this source it is what I use and it seems to be always up to date and very easy to use pcidatabase and it is an online search so you don't have to look through a list of numbers.04 lsusb and usb devices
This is pretty late and I'm sure you've already solved your problem, but I figured I'd address the other half of your problem that you overlooked quite possibly because you already knew this. But to others out there, device enumeration is another important of the application described here. I am not affiliated with these libraries, but I do suggest them: namely libusbx, libusb Learn more.
