USB Meltdown or is it just Vista ?

[timb]

Alright... I'm perplexed ! I have a somewhat unique set up that was running
fine up until a few days ago... I use a Microsoft "Enterainment Desktop
7000" keyboard and mouse (bluetooth) along with a Targus USB numeric key pad
(the MS keyboard doesn't have # keys)...

Along with vista loosing it's mind with regard to "sleep mode"... the "5"
key on the key pad seems stuck... ahhh... but it's not... it started with
the system sounding off with the repeated "clicking" noise from the
motherboard speaker... like the old buffer overflow when a keyboard key
would stick... if i click "start" in vista, the # 5 is filling in the "start
search" field... disconnect the key pad and it goes away... plug it back in
and fires right back up again...

Now... I've reinstalled the Nvidia chipset drivers, done a couple system
restores to previous "ok" states, reinstalled the video drivers, tried it at
both the default and overclocked settings below, tried all my USB devices in
different USB ports, did a virus and spyware scan, and tested the key pad on
a different vista 32-bit ultimate machine (it worked perfectly)...

SO... short of doing a clean install of vista (spits on the ground), might
it be a USB controller problem ? Any way of diagnosing that ? Anyway of
configuring the bios to manage voltages, etc. to the controller, etc. ????

I'm perplexed... any ideas would be most welcomed... system specs below...

thanks... m

It could be the Bluetooth keyboard. Have you changed the batteries in it
(don't trust the battery status indicator)? Checked it for a sticking key?
Tried a different keyboard?

Highly doubtful that this is a USB controller problem.

Sounds more like a keypad driver problem. What driver is loaded for this
keypad (version, date, provider)?

What are the hardwareIDs of the Targus keypad?

Start --> run --> devmgmt.msc --> device properties --> details -->
hardwareIDs

The 5 key doesn't have to be physically stuck down to be "stuck". Depends
on how the keyboard is constructed. The membrane below the key could be
deformed, someone could have spilled liquid on it at some point, etc..

Thanks everyone... I'll try and answer all the questions in this reply...

The drivers are standard Microsoft 6.0.6001.1800 6/21/2006...there were no
Targus drivers
The hardware ID's are:

HID\VID_05A4&PID_9862&REV_0110&MI_00
HID\VID_05A4&PID_9862&MI_00
HID_DEVICE_SYSTEM_KEYBOARD
HID_DEVICE_UP:0001_U:0006
HID_DEVICE

I did change the batteries in the bluetooth keyboard, tried it on another
machine (OK), re-installed it's drivers (MS too), tried a non-wireless
keyboard and mouse(no problems), checked for sticking keys on the keyboard,
pulled the # 5 key off the key pad and cleaned it out... and there hasn't
been any "spills" and nothings sticking when it (the keypad) was tested on
another machine...

Keep thinkin... and again thanks and HNY !
