Subject: Re: usb/101775: [libusbhid] [patch] possible error in report descriptor
parsing

I saw this error too (it is an error, see section 6.2.2.7, page 35, of
the USB HID 1.11 specification), but fixing this gave a physical minimum
of 32768 (no minus sign) instead of -32768 (with minus sign) for
"Generic_Desktop.{Rx,Ry,X,Y}" when plugging in an Xbox 360 controller.
/usr/src/sys/dev/usb/uxb360gp_rdesc.h (RELENG_6) shows (line 110):
0x36, 0x00, 0x80, /* PHYSICAL MINIMUM (-32768) */
so -32768 (with minus sign) is the correct value. I could not see any
sign error in the sources of libusbhid or usbhidctl though.
Any clues?
Regards,
Rene
