usb: usbtest: Add TEST 29, toggle sync, Clear toggle between bulk writes
Clear Feature Endpoint Halt should reset the data toggle even if the endpoint isn't halted. Host should manage to clear the host side data toggle to keep in sync with the device. Test by sending a "3 data packet URB" before and after clearing the halt. this should create a toggle sequence with two consecutive DATA0 packets. A successful test sequence looks like this ClearFeature(ENDPOINT_HALT) - initial toggle clear DATA0 (max packet sized) DATA1 (max packet sized) DATA0 (zero length packet) ClearFeature(ENDPOINT_HALT) - resets toggle DATA0 (max packet sized), if clear halt fails then toggle is DATA1 DATA1 (max packet sized) DATA0 (zero length packet) Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
