Hi, decided to join in, have read all of this thread, and have tried most things.
My problem is with my Trust 1200 Graphics tablet, which i have had since december 2003- no problems with it, ever.
But I got a new computer this january... and wahey, look what little message pops up when i connect it! bah.
(Some details...
Acer AMD Athlon 64 X2 Dual Core Processor 3800+ 2.01 GHz, XP Media Center Edition, service pack 2, version 2002. Ask if you need more. Its brand new so i wouldnt think anything would be outta date, has all the updates.)
I tried the unplugging thing (30mins). Nope
Checked BIOS. Nope
Deleted Registry unknown file crap... and it worked!.... for a few seconds anyway, then i think it fixed itself back to unknown device.
Something to note- it workes fine on another, similar computer, no problems at all... so i thought Id try and export the registry files from the pc it works on and copy them into my unknown device registry file.... this time when i plugged it in, it came up 'usb human interface device' but sadly didnt work... it was a longshot, lol!
So yeah... if anyone wants to try that method they should... may work for them... and if anyone has any suggestions for me, yay!
Cheers, penguin
