Guest R. McCarty Posted October 9, 2008 Posted October 9, 2008 Re: Know of a USB Trouble Shooting Utility What kind of trouble ? - Device won't install/detect properly or other type of issue. If certain devices work and others do not it might be an issue with your USB controller. Usually a PC has one for USB 1(.1) and another USB 2.0. It could also be a Hub power overload. Generally Device Manager is a good tool for diagnosing issues. Check for "Unknown" devices or review Bandwidth/Power Consumption on the Controllers & Hubs. If the issue only started very recently, you might consider a System Restore back a few days.

For some reason, they decided to remove it. While web.archive.org has a copy, I discovered that the last byte of the file is missing (0x00 hex), which prevents the tool from running in WinXP. Therefore, the following two links, are copies I found on the net. The MD5SUM matches the old copy I got from Microsoft, and the file info is included below. ******* ftp://ftp.efo.ru/pub/ftdichip/Utilities/UVCView.x86.exe http://www.users.on.net/~fzabkar/USB_IDs/UVCView.x86.exe File size is 167,232 bytes. MD5sum is 93244d84d79314898e62d21cecc4ca5e This is a picture of what the UVCView info looks like. http://www.die.de/blog/content/binary/usbview.png Some information on the parameters seen in UVCView. http://www.beyondlogic.org/usbnutshell/usb5.htm ******* As utilities go, there isn't that much to it. What it shows, is the enumeration info coming from the device. Also, the endpoints that have been set up will be shown. If no endpoints are set up, then you know there is a pretty low level communications failure. This describes the basic process, of how a device is detected, but there is more going on after this, that is not described. There are a number of standardized device classes (like USB Mass Storage), and protocol stacks that go with them, and that is part of the setup as well. http://www.lvr.com/usbcenum.htm UVCView doesn't test anything. There are probably commercial products out there that do some form of testing or protocol monitoring, but anything that costs money, is out of my league :-) I'm just a cheapskate at heart. HTH, Paul
