Remember that the GPIF is currently set up to DMA 256 16-bit values.
Perhaps that part needs changing. The magic value is probably buried
in the WaveData table in usrp_gpif.c
I looked over the GPIF stuff with the Cypress tool I do not see any
reference to transfer size in there. I am thinking

What is the source of the data you're transferring over the bus? If
it is com
I've been working on adding USB1.1 (full speed) support to the USRP
software/firmware so I can use it with a TI OSK board. I've been going
back and forth with Matt on some issues and we are getting out of his
area of expertise. Here is summary of progress to date.
After modifying the 8051 code I

I've been working on getting the usrp working with a USB full speed
interface connected to an OMAP starter kit (OSK) board from TI. I'm
not using GNU Radio, but the OSSIE open source SCA. The OSK only has a
USB 11 controller that sends 64 byte packets, not the 512 byte packets
sent by USB2.0 high
