Bug Description
USB devices (such as USB flash storage, USB mouse, etc) worked in kernel version 2.6.31-20 and prior (perhaps Ubuntu 10.04 kernel?), but stopped working in 2.6.35-22 and thereafter.
When a device is plugged in, it is indicated via dmesg of the device being detected, but nothing afterwards (no errors and so on).
For example, plugging in a USB device under a non-working kernel version (dmesg):
[ 144.156079] usb 1-4: new high speed USB device using ehci_hcd and address 2
And under the kernel version that USB devices work properly:
[ 134.640072] usb 1-4: new high speed USB device using ehci_hcd and address 2
[ 134.894173] usb 1-4: configuration #1 chosen from 1 choice

I've finally found a pattern to this bug as it seemed fairly sporadic.
It appears that USB will work on 2.6.35-22 and after ONLY if a USB device is plugged in at boot (such as at GRUB menu; or before being turned on)
Whereas on 2.6.31-20 and prior, USB will work regardless if a device is plugged in at boot or not.
