A bug was introduced in 2.6.27 and the fix is queued for 2.6.27.stable.  
The fix takes the form of two patches, which you can find here:

http://mirrors.med.harvard.edu/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/ohci-allow-broken-controllers-to-auto-stop.patch
http://mirrors.med.harvard.edu/linux/kernel/people/gregkh/gregkh-2.6/gregkh-04-usb/usb-ohci-fix-endless-polling-behavior.patch

The second depends on the first, so you have to apply them both.
