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.
