[libhid-discuss] setting output problems

[Hans-Christoph Steiner]

Hey,

I am trying to get my code to output properly and having trouble.  I  
was hoping someone could show me some simple example code just to  
send an output report.  So here are the paths reported from libhid:

   path: 0x00010005.0x00010030; type: 0x90
   path: 0x00010005.0x00010031; type: 0x90
   path: 0x00010005.0x00010032; type: 0x90
   path: 0x00010005.0x00010033; type: 0x90
   path: 0x00010005.0x00010034; type: 0x90
   path: 0x00010005.0x00010035; type: 0x90
   path: 0x00010005.0x00010036; type: 0x90
   path: 0x00010005.0x00010037; type: 0x90

Apple USB Prober says that they each have a Report Size of 16 and  
there is a report count of 8.  Here's the code I tried, it doesn't  
give errors, it just doesn't seem to work:

int path[] = {0x00010005, 0x00010030};
unsigned int const depth = 2;  // number of 32bit chunks in the path
unsigned char const SEND_PACKET_LEN = 2; // number of bytes in packet
char const PACKET[] = { 0x00, 0x00 }; // the data to write
//char const PACKET[] = { 0xff, 0xff }; // the data to write

if ( !hid_is_opened(x->x_hidinterface) )
{
	printf("[usbhid] device not open, can't set data");
	return;
}

x->x_hid_return = hid_set_output_report(x->x_hidinterface,
					path, depth, PACKET,
					SEND_PACKET_LEN);
