Give up after 5 errors in UsbConnectionReader
Previously a zero-length read was raised as a sign of error every 5
errors. However this meant reams of errors and invalid messages being
sent if a Connection was active to the device while it was unplugged.
The first invalid message is sufficient, since Connection will reset in
response.
