I gave a try to to this patch using your test tool [1] and very old BT
keyboard. I don't have anything else ATM to test with. Is there some BT hid
devices which support setting and getting features?
Shouldn't HIDIOCSFEATURE's bt version have similar wait as HIDIOCGFEATURE to
get report status back from the device? or is there even any status coming back
in successful case? Sorry I'm a newbie with HID and trying to understand how
this should work.
Now it just returns num of send bytes even if the remote device returned some
error. Which one is the expected behavior?
Other problem is that Get report is getting now handshake from set report.
