usb turns off, machine wont

[Ingber]

I am running XP prof. SP2 on an old machine that was working fine with this
setup. Something changed some months ago such that:

After working fine, the USB 1 port shuts down at an apparently random time.
I can continue with a PS2 mouse when the USB mouse shuts down, but using a
camera or scanner is not possible without a restart. Device manager always
reports that it is working fine.

After the occurrence of a USB shutdown it is not possible to exit windows
normally to a power down. The Windows shut down cycle seems to be going on
but the power does not ever get cut. If I wait till the disk drive light
stops blinking with any frequency, a manual shutdown using the front power
switch will work and a normal boot will occur on the next bootup without a
disk scan. The shutdown is quite normal if the USB shutdown has not yet
occurred.

I have not been able to find this particular problem described and solved.
Any suggestions?

If it's the mouse that's causing the problem, stop using a USB mouse.
Personally, I NEVER EVER use USB mouse or keyboard. PS/2 uses a dedicated
bus...so there is no chance of conflict. Make sure you have all of the
laitest software and drivers installed for all USB devices....

and be sure to get rid of USB mouse and/or keyboard!!!!

Thanks, but the mouse does not seem to be the source of the problem. I have
uninstalled, reinstalled and updated drivers for just about everything.

Take the cover off the computer; when this happens measure the voltage
of the USB pins on the mother board and see if your getting any...

I had a mother board once that had two USB connectors on the MB but
only one work'd.

Well, in that case it may be a hardware problem. You can now buy a 4 port
USB PCI card for next to nothing...if you do buy one, make sure it supports
USB2.0

Has absolutely NOTHING to do with using a USB mouse/keyboard!!! (enuf
exclamatin marks?). Windoze is a toy operating system that seems to just
breakdown like this for no apparent reason. It is not a stable o/s. XP
users just have to learn to live with the Windoze eXPerience - part of
which is needing to reboot to get things somewhat stable for a period of
time.

The box with the two USB connections is soldered to the MB with no access to
the back of the board when both sides of the tower box are removed. The MB
is screwed to a backing plate. All connections on the rear of the board
would have to be pulled and the MB unscrewed and pulled out of the box. If
I can't find another the solution I might have to try this, restart the
machine with the MB hanging out and wait for the failure. Both the
connectors lose power when there is a failure.

I guess the obvious answer would be - are you using an optical mouse
and does the led go out when this happens - if so it's a voltage
problem. If not maybe not.

Not true, as I mention'd I had one that had power one that never
work'd. both series of pins right next to each other.

Why don't you learn what you are talking about before you spout such drivel?
The only time I ever shutdown or reboot any of my systems is for
installation of patches--in other words not more than once per month two
days after Patch Tuesday (OK, so I'm paranoid and test all patches before
system-wide deployment).

I am a Linux fan myself (I prefer Debian distros), but you do nothing to
help promote alternative OSes with your useless rhetoric.

Try actually helping people or offer alternatives and people will take you
seriously. Spouting off useless "windoze" bs simply gets you ignored by
people who may be interested in trying one of the more user friendly
distros.

For users wanting more info on Debian, go to http://www.debian.org/

If you aren't comfortable with making the jump all at once, download a
version of Knoppix which boots from cd, play with it and learn your way
around KDE and Linux based apps.

Not true, as I mention'd I had one that had power one that never
work'd. both series of pins right next to each other.

I meant that in my case both connectors lose power and/or connectivity. The
light in the optical mouse does go off. However, in the case of a camera
and my scanner, plugged into the other connection, there is no connectivity
either. I do not know whether these devices use the power at all. The
scanner has external power, of course. There is no indication of any USB
device when looking in "my computer" after the port shuts down.

Start | Run <type in> devmgmt.msc <enter>

Under USB find your mouse, under power it should show voltage supplied
but I've never look'd when there was none

I also noticed a power management option to allow the computer to shut
this device down - might want to uncheck that one..

and go down the list of USB devices and see what's shown

- might keep the power shown so when you lose it you can view it.

Thanks. The only power indications are under the USB hub, not the mouse.
The two devices are listed with the amps required (not supplied) and the
display does not change when the port goes off. I have also tried every
permutation of power management - allowing (or not) to bring out of standby;
allow (or not) to save power. Nothing has helped in the past.
It might yet be a hardware problem. Perhaps the suggestion to install a card
with some ports would finesse the problem, but it would be nice to really
solve it.

 

[mikeyhsd]

under Device Manager | Device Management | USB devices and the properties , disable under POWER tab the ability to disable usb port to save power.
