Title:
  Via USB and ehci_hcd bug: USB not recognized - IRQ issue

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux-meta” package in Ubuntu:
  Invalid
Status in “linux-source-2.6.17” package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: linux-image-2.6-386

  On Ubuntu Dapper Drake, with all updates applied, USB devices are not
  recognized anymore (they used to when Dapper was freshly released).

  Problem may come from ehci_hcd, as removing this module (modprobe -r
  ehci_hcd) fix the issue, but then USB devices are stuck on 1.1 low
  speed standard.

  Another solution seem to set acpi=noirq at boot time, but didn't fix
  the problem for me (it did for some other people however).

  More googling showed me that this problem is ongoing and has appeared
  in the past as well. Some kernel issue here.

  Here is what happens when I plug a USB device in (dmesg output):

  [17185074.604000] usb 4-1: new high speed USB device using ehci_hcd and address 2
  [17185075.604000] ehci_hcd 0000:00:10.3: Unlink after no-IRQ?  Controller is probably using the wrong IRQ.
  [17185086.148000] usb 4-1: device not accepting address 2, error -110
  [17185086.260000] usb 4-1: new high speed USB device using ehci_hcd and address 3

  
  "Controller is probably using the wrong IRQ" <- There we go: IRQ problem. Still, set acpi=noirq at boot time doesn't fix anything.

  
  Here's my lspci output:
