//TODO: Use hotplug or give permission to USB without sudo
/* How to detach a device from the kernel HID driver:
*
* The hid.o or usbhid.ko kernel modules claim a HID device on insertion,
* usually. To be able to use it with libhid, you need to blacklist the
* device (which requires a kernel recompilation), or simply tell libhid to
* detach it for you. hid_open just opens the device, hid_force_open will
* try n times to detach the device before failing.
*
* To open the HID, you need permission to the file in the /proc usbfs
* (which must be mounted -- most distros do that by default):
* mount -t usbfs none /proc/bus/usb
* You can use hotplug to automatically give permissions to the device on
* connection. Please see
* http://cvs.ailab.ch/cgi-bin/viewcvs.cgi/external/libphidgets/hotplug/
* for an example. Try NOT to work as root!
