[libhid-discuss] Broken pipe yet again

[alfredo alvarez]

Here is the output from a run of my program it includes the error i also wanted to mention that the program ( firmaware) actually gets detected by my machine and runs with the normal windows driver fine. but when i try to use it to get a report i can't. If it is the firmware anywhere i can get a working example or someone i can talk to ?

Can you send the exact error message?

Note that depending on what error code you are seeing, it may be a  
problem with the firmware (e.g. it does not support the transfer in  
hid_get_input_report().)
