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
[ 101.760094] hub 4-0:1.0: unable to enumerate USB device on port 5
[ 102.000128] hub 2-0:1.0: unable to enumerate USB device on port 5
[ 102.212187] hub 4-0:1.0: unable to enumerate USB device on port 5
[ 102.452196] 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

finger@larrylap:~/wireless-testing> lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 0409:005a NEC Corp. HighSpeed Hub
Bus 001 Device 003: ID 04f2:b016 Chicony Electronics Co., Ltd VGA 30fps UVC Webcam

Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

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
