This just occurred to me: After a suspend/resume, when the uhci_hcd driver doesn't recognize new devices being plugged in, can you tell if the interrupt count for the driver is changing? If the host controller doesn't share an IRQ, the numbers in /proc/interrupts will tell the story. As another test, what shows up in the debugging file for the controller? Under 2.6.9 that file would be in the /proc/driver/uhci/ directory, but it was recently moved to the debugfs filesystem, and I'm not sure whether that move was done before or after 2.6.10 was released.
