Good news! The mystery is finally solved.
In further researching my problem, I found several posts on other forums about users experiencing similar issues due to conflicting IRQ assignments. Their solution was to add the following boot-time parameter:
"NOAPIC"
I tried adding this parameter, and miraculously, all of the USB devices came to life! The printer, wireless mouse, PocketPC dock and thumb drive all work perfectly. Hotplugging works too... when I insert the thumb drive, the device is displayed almost immediately within Konqueror.
In my case, the culprit must have been IRQ 11. Now in my startup log, I see these entries, that didn't exist prior:
PCI: Sharing IRQ 11 with 0000:00:1e.3
PCI: Sharing IRQ 11 with 0000:0b:00.2
What's more, although not a USB device, my local network connection is also now working. Perhaps IRQ 11 was being used for both the network and USB controllers.
Thanks to everyone for all of your help!
Best regards,
Bob
