Something doesn't look right here, and I don't have time to fully  
investigate right now.

Basically, it should not be sending a report ID if there are no  
report IDs defined in the HID report descriptor (note that it says  
"length: 6" but you passed in an array of 5 bytes).

For the hid_interrupt_read error, you may need to set the USB_DEBUG  
environment variable to something non-zero.
