<br>Hi:<br><br>I am using hid_interrupt_write() and hid_interrupt_read() to talk to my HID device. But both calls come back with an error saying:<br><br> "could not claim interface 0: Device or resource busy".<br>
<br>But my hid_force_open() issues earlier in the same code (and remains open) was successful. <br>Shouldn't hid_force_open() already claim the required interface so interrupt_write/read can use <br>the claimed interface?
<br><br>Or am I missing a step in between open and write/read so that interface can be used?<br><br>thanks<br><br><br>Mark<br>
