I have a type of hid device. I use the USB Prober tool to see the device's number of Interface is 2, and each interface contains one Endpoint - Interrupt Output.

Now I use WritePipeAsync to write data to device successfully.but i can not read data from device because the device has not Out endpoint.

But the device exactly read and write data in windows os. How could i do?
Thank u!
