USB problem


S

Steve T

Running XP-SP3 with all updates current. I have a WACOM tablet, driver is
latest version; plugged into a USB port in rear of DELL PC. I'll boot up and
get error message,"USB device not recognized...". I check Device Manager and
no flags are showing. I simply plug into another USB port and I get message
that "Human Interface Device found" and my tablet now works. The next day I
boot up and the same error message pops up and the fix is to reverse what I
did the previous day, just plug back into yesterday's "bad USB port". Any
ideas what I am chasing here? Thank you, Steve T.

This Almost sounds like a voltage issue
(or even a cold solder joint but it switching is odd that's for sure.)

How many things do you have plugged into your USB Ports?
If you have an Extension that is NOT powered you may be trying to draw too
much voltage.

If you have daisy chained many devices even 1 or 2 more it may be drawing
too much power.

To test remove the un needed devices upon power up and see if that solves
it.
If it works then try getting a "POWERED" USB 2.0 port extension and see If
that solves the issue.

Can you also try a different USB cable for the Device?

I don't know what exactly your problem could be, and the following are
just some leads to tools and suggestions.

*******

Implicit in what you're saying here, is unplugging it and plugging it
into the *same* port, isn't getting the device recognized. That you
have to change ports for it to work.

To test Russ's theory that the issue is electrical, try unplugging it
for two minutes (sufficient time for a Polyfuse to recrystallize), then
plug it into the *same* port. If it malfunctions on the same port again,
the implication would be it is a software problem.

In terms of overcurrent protection on a port, on a desktop it is likely
to be implemented in pairs. The connectors on a "stack of two" USB ports
are likely connected to the same Polyfuse. Moving the USB cable from one
port in a "stack of two", to the other, should not materially affect the
electrical powering situation, and if there was an overcurrent problem, the
misbehavior should continue once you move from one port in the stack
to the other. All my motherboards here are fused in such a way. Laptops
seem to be different, in that a laptop may use a silicon device for
controlling overcurrent, and a small 8 pin DIP cuts off the current.
Laptops should be much more precise about overcurrent, as a result.
And the laptop policing of current flow, should be separate for each
port.

I haven't tried looking through the registry for it, but USB
devices are remembered from one usage to another. For example, if
the USB device has a serial number, then Windows can give a more consistent
response to the device, as it would recognize it had been used before.
If a device doesn't have a serial number, then each plug-in causes
re-installation (perhaps using built-in software stacks such as
HID or USB Mass Storage).

You can look in the file "setupapi.log" and see installation activity
at work.

You can also use UVCView, to look at the config data coming from the device.
I doubt that is going to help in this case, because all you're going to
see, is no endpoints set up for the failed case, and endpoints set up
in the success case. (UVCView is a Microsoft program, no longer offered
for download. The copies on archive.org were also removed, presumably
at Microsoft's request.)

That leaves some kind of registry issue. There are some
troubleshooting suggestions here, for various sets of
symptoms.

ya I was thinking It might be integrated.
Hmmm

Do you have a friend you can test it out on?
(See if it behaves the same for them?)

also you might try uninstalling the device drivers
completely and re installing them.
(Also see if the manufacture has new software for it.)

Today, it booted up the PC and the tablet was lit up thus no error messages.
Later, after awakening the PC; the error message returned regarding "USB
device not recognized..." I unplugged USB and plugged back into same port
and tablet was back on. I uninstalled software for tablet, rebooted and
noted that power light was not on tablet. During install of software for
tablet, it indicated that there was a problem as there was no tablet found
(plugged in entire time). I unplugged cable, re-inserted into same location
and Install proceeded. Now I'm waiting to see what happens next. Next time
it screws up I'll unplug for two minutes and see what happens.
