Message-ID: <4CCE1C11.6050807@lwfinger.net> (raw)
With the current mainline pull (get describe shows v2.6.36-9871-g3985c7c), my
logs are spammed with

[ 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

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
