|
Interrupt Transfers
|
Used for sending small amounts of bursty data that requires a guaranteed minimum latency. This transfer uses a data pipe.
|
|
|
Bulk Transfers
|
Used for large data transfers that use all available USB bandwidth with no guarantee on transfer speed or latency. This transfer uses a data pipe.
|
|
|
Isochronous Transfers
|
Used for data that requires a guaranteed data delivery rate. Isochronous transfers are capable of this guaranteed delivery time due to their guaranteed latency, guaranteed bus bandwidth, and lack of error correction. Without the error correction, there is no halt in transmission while packets containing errors are resent. This transfer uses a data pipe.
