ME | USB and VIA chips...

[Kurt]

I've heard lots of opinions, but why would my umax usb scanner be
"unknown" the device manager after working one day and not the next.
I've applied all the latest patches and upgrades to mb, os and scanner.

I think the culprit is the via chipset used. Btw, I'm on a amd 800 w/
256 mg ram, asus a7v mb.

Thanks for any info.

Hi Kurt -

I have exactly the same problem with my Abit KT7 motherboard - I think it has the same VIA KT133 chipset as your board. My scanner and printer would work for a short while and then hang. They'd appear in device manager, but would stop responding within minutes of booting up.

I had no luck installing VIA 4-in-1 Drivers version 4.25 or 4.26 or the USB Filter Driver version 1.08. Another recommendation I received was to turn off error detection on the USB Hub in Control Panel|System|Device Manager - no joy there, either.

I finally solved my problem by adding a cheap add-on board, providing me with two additional USB ports. My scanner and printer work perfectly with the add-on board. Funny, though, my Logitech USB Optical mouse works fine with the on-board USB ports.... go figure.

An interesting thought: my mouse receives all it's power from the USB port. The printer and scanner do not... could this be a coincidence?

I thought the Abit board, with 4 on-board USB ports would be great... if only I could use them!

Sorry I couldn't be of more help. If you haven't tried the 4-in-1 4.25 drivers (I don't recommend the 4.26 because they're not an official release), the USB Filter Driver 1.08 or disabling USB error detection, you might give it a whirl.
