Thanks for answering and sorry for being unclear.
This is/was on Linux (Lubuntu).
I'm writing a generic library and using a cheap
blue no brand game pad from China to test it.
I can enumerate and find the device but when I
try to open the device I get 13/EACCESS.
If I run my code as root then I can open and
use the device without any problems, so I guess
this access rights problem, not os driver hogging
it ?
I've added the following udev rules:
nyholku@KustinLubuntu:/media/psf/Home/hidapi/linux$ cat
/etc/udev/rules.d/10-myrules.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="0810", ATTRS{idProduct}=="0005",
MODE="0666"
KERNEL=="hidraw*", ATTRS{busnum}=="1", ATTRS{idVendor}=="0810",
ATTRS{idProduct}=="0005", MODE="0666"
Also tried them with 99- prefix, but no joy.
