Looking at it again, maybe there should be an OP_START to either start the RX or TX depending on it either being an IN or OUT packet? Otherwise, how would you know when to actually begin performing the desired action? What do you think? Brian ___ Dis

Some preliminary questions: How are the operations linked with the transmit sequences? Are operations sent down in bulk, or one at a time? Will the RX chain simply start and return 504-byte length packets until the next TX timestamp is sent down? Could this starve the USB bandwidth? Brian _
