EXCEPTION_STS (EXCP_STS_0): Read-Only. This field indicates the
exception when the ERROR_GOOD#_STS bit is set. This field should be
ignored if the ERROR_GOOD#_STS bit is 0. 000 No Error. Note: this should
not be seen, since this field should only be checked if there is an erro. 001
Transaction error: indicates the USB2 transaction had an error (CRC, bad
PID, timeout, etc.) 010 HW error. Request was attempted (or in progress)
