ChangeSet 1.1722.83.6, 2004/06/02 13:25:59-07:00, [EMAIL PROTECTED]
[PATCH] USB: usb retry cleanups
This patch stops changing the reported fault mode in cases where retries of
GET_DESCRIPTOR fail because the device just doesn't have such a descriptor.
Plus, it stops printing messages when retrying.
It also reduces the number of retries; the first retry seems to resolve most
of these firmware problems.
