I am currently having trouble with Gigabyte GA-6BXD, dual Pentium III motherboard. If I boot a UP kernel (5.0-CURRENT), the PIIX4 USB controller works fine. If I boot a SMP kernel (the only difference from the UP kernel is support for SMP), the kernel seems unable to communicate with the USB device. When I plug a USB keyboard, I get uhci_timeout: ii=0xc0a601c0 uhci_timeout: ii=0xc0a601c0 uhci_timeout: ii=0xc0a601c0 usbd_new_device: addr=2, getting first desc failed uhub_explore: usb_new_device failed, error=TIMEOUT uhub0: device problem, disabling port 1 I vaguely remember someone also reported similar problems with the SMP kernel in the past.... Interesting thing is that I have another SMP box, and its USB works fine. The version is 4.0-STABLE. The USB controller is VIA 83c572.
