[Guest RobertA]

I am having trouble on my notebook with usb devices except for a mouse. Does

anyone know of a utility to lookat/troubleshoot usb devices? Windows says

everything is fine.

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.

Microsoft used to have a utility for download on their web site.

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.

Some information on the parameters seen in UVCView.

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.

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.
