Hello I cannot make work the parameter use_dma_chaining with g_mass_storage and a usb3380 device. The initial enumeration works, but after a couple of frames the enumeration is restarted. If I compare usbmon with and without the parameter I can see that the device fails to reply to the host.
While going through the code I realized that there is only on scathe gather descriptor per endpoint and I wonder how can you make work a dma_chain with only one descriptor!. I think the driver is expecting a special pattern of execution or maybe (probably) I am not understanding the code right. Can somebody confirm that this parameter works on a net2280, and if not, can I remove the obsolete code, so no other person loses some hours and gray hair :) ?
