Hi Alexander,

you start this thread on the mailing list, so keep it there ;)

I can't tell you how it is with hiddev, but the report ID 16 has six
bytes and the report ID 17 has 19 bytes. Count for yourself.

	Usage Page (Undefined)
	Usage (0x01)
	Collection (Application)
	  Report ID (16)
	  Report Size (8)
	  Report Count (6)
	  Logical Minimum (0)
	  Logical Maximum (65535)
	  Usage (0x01)
	  Input (0x0000)
	  Usage (0x01)
	  Output (0x0000)
	End Collection

	Usage Page (Undefined)
	Usage (0x02)
	Collection (Application)
	  Report ID (17)
	  Report Size (8)
	  Report Count (19)
	  Logical Minimum (0)
	  Logical Maximum (65535)
	  Usage (0x02)
	  Input (0x0000)
	  Usage (0x02)
	  Output (0x0000)
	End Collection

With what kind of code?

Trust me that it is better to check it in detail. You always have to
know why you are doing some things this way and I don't know it right
now.
