gadget-ffs example

[nandra]

Hi,

this is not an issue but general question. I want to check sending data over USB gadget so I used ffs gadget. This case input and output endpoints are created. I wrote small program using libusb1 to sent data to device. What bit puzzled me how to read data from endpoint. I see ffs/ep1 but when run cat ffs/ep1 got nothing. I tried to use simple aio-examples from kernel sources but result is same. Am I missing something? Thanks a lot.
