Max length USB2 packets are 512 bytes, and that is all that we use.
The FIFOs in the FPGA are each 8192 bytes (16 packets), one for TX and
one for RX. This is limited by the RAM in the FPGA. At full data speed

Regarding BSD ugen(4) support for the USRP, I have a few questions
about desired transfer sizes. With ugen now, and with Linux URBs, the
size of each USB transaction is cont
