Ok, I was hoping COMP_SUCCESS event->len in case 2 and 3 would show the same value as the previous COMP_SHORT_TX event->len >>> >>> The other thing I thought of was to somehow always initialize the URB >>> actual length to the transfer buffer length from the very beginning, >>> and only update it if a COMP_SHORT_TX event is received.

I already started implementing a testpatch, will send it shortly If you'd like to test it with your device and hso driver. -Mathias -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
