Error codes
Description
no error
PID encoding error; bits 7 to 4 are not the inversion of bits 3 to 0
PID unknown; encoding is valid, but PID does not exist
unexpected packet; packet is not of the type expected (= token, data or
acknowledge), or SETUP token to a non-control endpoint
token CRC error
data CRC error
time-out error
never happens
unexpected End-Of-Packet (EOP)
sent or received NAK
sent stall, a token was received, but the endpoint was stalled
overflow error, the received packet was longer than the available buffer space
bit stuff error
wrong DATA PID; the received DATA PID was not what was expected
