With the current mainline pull (get describe shows v2.6.36-9871-g3985c7c), my
logs are spammed with

[  101.308220] hub 4-0:1.0: unable to enumerate USB device on port 5
[  101.548357] hub 2-0:1.0: unable to enumerate USB device on port 5

[  102.664131] hub 4-0:1.0: unable to enumerate USB device on port 5

The USB devices on my system are

I had this problem in the past when ohci_hcd was being loaded before ehci_hcd,
but that is not the case now as is shown by lsmod:

mbcache                 7798  1 ext3
ohci_hcd               22322  0
sd_mod                 29184  4
ehci_hcd               37829  0
usbcore               158887  4 r8712u,ohci_hcd,ehci_hcd
