[Bug 318085] Re: Unable to enumerate usb device

[disco_stew]

I would like to second Bryan Hoyt's comments that this bug is very real
and not the same as other bugs that sound similar (not a device problem,
kernel problem, boot problem, etc.). I have been experiencing the
*exact* same symptoms:

1) Plug in usb key.
2) Key does not automount, but I/O light flashes intermittently.
3) Flood of "high speed USB device using ehci_hcd and address X" and "unable to enumerate USB device on port X" messages when checking dmesg.
4) Wait between 15-60 minutes and key is mounted (although sometimes never).

It is worth noting that this has only been affecting me for the past 1-2
months, before which I never had any usb connectivity problems.

I do not wish to cripple my system by dropping down to "full speed" usb
transfer rates, so I hope somebody has a real solution.
