I have a bit of a problem with generating a HID descriptor. I want to use simple reports with ID1 for input and ID2 for output with 64 bytes of data.
I realized that
I've got my custom HID device detected by Windows 7 with this (built by guess and stealing from examples):
{
0x05, 0x01, // USAGE_PAGE (Generic Desktop)
0x09, 0x00, // USAGE (Undefined)
0xa1, 0x01, // COLLECTION (Application)
0x15, 0x00, // LOGICAL_MINIMUM (0)
0x26, 0xff, 0x00, // LOGICAL_MAXIMUM (255)
0x85, 0x01, // REPORT_ID (1)
0x75, 0x08, // REPORT_SIZE (8)
0x95, 0x40, // REPORT_COUNT (64)
0x09, 0x00, // USAGE (Undefined)
0x81, 0x82, // INPUT (Data,Var,Abs,Vol) - to the host
0x85, 0x02, // REPORT_ID (2)
0x75, 0x08, // REPORT_SIZE (8)
0x95, 0x40, // REPORT_COUNT (64)
0x09, 0x00, // USAGE (Undefined)
0x91, 0x82, // OUTPUT (Data,Var,Abs,Vol) - from the host
0xc0 // END_COLLECTION
}; /* CustomHID_ReportDescriptor */
I'm not sure if it will work properly though. We will see.
