What am I doing wrong?
This does not seem right:
ret = hid_interrupt_read(hid, USB_ENDPOINT_OUT+1, (void*)&packet,
sizeof(packet), 1000);
The "_OUT" direction is relative to the PC, so a _read needs to have
an _IN endpoint, and a _write needs a _OUT endpoint.
Given the following section in lsusb, it should probably be
USB_ENDPOINT_IN+1:
Endpoint Descriptor:
bLength 7
bDescriptorType 5
bEndpointAddress 0x81 EP 1 IN
bmAttributes 3
Transfer Type Interrupt
Synch Type None
Usage Type Data
wMaxPacketSize 0x0008 1x 8 bytes
bInterval 1
