Title: Send DFU_ABORT command to USB device Control EP
Post by: cgopalg on February 06, 2014, 12:46:28 am

Hi,

I want to send DFU_ABORT command to my USB device for Control End Point via WinUSB Control Transer API.
However I got the error semaphore timeout from WinUSB API though my device received the DFU_ABORT command.

Can someone help me on the above? Why error is returned by WinUSB API?
Is there any other means to send the DFU_ABORT command to my USB Device?

Does you device successfully complete the status phase? What do you see on the bus?

Hi,

Thanks, the status phase was not complete. Now it is OK.
