When we run input04 on RHEL 5.11GA and 6.7GA, it still fails. It gives error message like this: input04 0 TINFO : Found uinput dev at /dev/uinput input04 0 TINFO : Unexpected ev type=0 code=0 value=0 input04 1 TFAIL : input04.c:65: Data received /dev/inputX I think that this failure is because kernel sends empty events. i.e If we only send EV_SYN to input device, nothing should be received in /dev/input/eventX. Actually, data is received in /dev/input/eventX. This investigation shows that it may be improved by following patch: 'commit 4369c64c79a2 ("Input: Send events one packet at a time")'. Could tell me the real reason for the case failure. I'm just not familiar enough with the code. Regards, Xiao Yang
