This one's a doozy.......
abit IP35Pro motherboard (http://www.uabit.com/index.php?option=com_content&task=view&id=110&Itemid=2
Intel Core2 Duo CPU, 2.20GHz
Main Memory = 2GB RAM
Motherboard has 4 backplane USB Ports plus two additional front panel ones as well.
All MB drivers provided by abit installed and operational in XP.
Windows Vista Business upgraded from Clean Windows XP Pro.
Prior to the upgrade to Vista Business, Windows XP Pro worked flawlessly with ALL USB devices. USB Flash Drives, USB Camera, USB anything.
Upgraded to Vista Business.
After upgrade completed, activated, validated, tested and DNA samples provided to M$, the following devices were operational on the USB ports:
HP PSC2355 All-In-One printer with integrated flash card reader (5 types, plus additional USB connection) - Printer operational 100%, however, system wants to install drivers for "Unknown Device" every time the system starts up.
USB Bluetooth keyboard and mouse (MX5000 Laser by Logitech) - 100% operational.
First time I plugged my Imation 1gb Flip-Flash drive into the front panel USB Port, I got a ton of errors, all around "Windows needs to install a driver for you hardware"
I googled, yahoo'd and asked Jeeves and did everything I could come up with from those and we're at the following point:
Whenever I insert an card into my multi-format card reader on the Printer, or when ever I insert a flash drive, I get a "Safely remove Hardware" icon in the systray and that shows a USB Mass Storage Device, however, no drives show up in My Computer at all. I get no hits, no runs, no errors at all, just an additional "Unknown Device" added to my Device Manager for each different type of device I connect.
Anyone got any ideas on this? I'm at the end of my rope and I'm about ready to flush M$ down the drain.
