Name
Status update Description
by HC
ActualBytes[9:0]
Yes
This field contains the number of bytes that were transferred for this PTD.
CompletionCode[3:0]
Yes
0000 NoError
General Transfer Descriptor (TD) or
isochronous data packet processing
completed with no detected errors.
0001 CRC
The last data packet from the endpoint
contained a Cyclic Redundancy Check
(CRC) error.
0010 BitStuffing
The last data packet from the endpoint
contained a bit stuffing violation.
0011
DataToggleMismatch The last packet from the endpoint had data
toggle Packet ID (PID) that did not match the
expected value.
0100 Stall
TD was moved to the Done queue because
the endpoint returned a STALL PID.
0101 DeviceNot
Responding
The device did not respond to the token (IN)
or did not provide a handshake (OUT).
0110 PIDCheckFailure
The check bits on PID from the endpoint
failed on data PID (IN) or handshake (OUT).
0111 UnexpectedPID
The received PID was not valid when
encountered, or the PID value is not defined.
1000 DataOverrun
The amount of data returned by the endpoint
exceeded either the size of the maximum
data packet allowed from the endpoint (found
in the MaximumPacketSize field of ED) or the
remaining buffer size.
1001 DataUnderrun
The endpoint returned is less than
MaximumPacketSize and that amount was
not sufficient to fill the specified buffer.

1100 BufferOverrun
During an IN, the HC received data from the
endpoint faster than it could be written to the
system memory.
1101 BufferUnderrun
During an OUT, the HC could not retrieve
data from the system memory fast enough to
keep up with the USB data rate.
