Dear all, I am trying to develop a driver for the net2280 successor (USB 3380 from PLX). I'm fairly new to Linux driver development, so apologies for my ignorance. With some small modifications I was able to re-use the existing net2280 driver. However, when using usbtest with gadget zero I have the following behavior: $ ./testusb -s 512 -t 1 -c 2 hangs $ ./testusb -s 1024 -t 1 -c 2 succeeds, if gadget zero buflen is 1024 Is this the intended behavior? Any writes/reads falling short of the gadget zero buffer length, cause testusb to hang (USB activity LED on the net3380 is on, during this time though). A single read/write (testusb ... -c 1) succeeds regardless of the size (matching or not matching the zero buffer length). Thanks, Thomas. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
