It's a bootloader, and not SA1110 :). (ARM920T from Samsung) Though I do plan on porting that usbnet driver to this board when I finish on the other elements of the kernel. > Are you doing synchronous transfers? Synchronous..., do you mean isochronus? (Or something like that, where you schedule it to happen at certain times or something like that) No, just bulk transfers. > You should be able to just dump big data segments into the URB, and > it will crank out.

A bulk transfer can only take as much data as the fifo on the device side can take. In my case it's 64bytes. I will review the USB spec though tomorrow. (I was hoping for a- hey bozo, do it this way :) Probably I'll just go with what I have for now unless someone has a quick solution, I'll retrace back and look at it after the baseline port is done.
