Issue 59: USB Device Controller: DMA does not work
Reported by w, Apr 3, 2010
The USB Device Controller currently uses only PIO. Therefore Ethernet over USB is damn slow. When DMA is enabled in jz4740_udc.c USB does not work at all. I don't know why. Sadly g_file_storage gadget seems only to work when DMA is available which would be a nice feature on Ben.
