+	This allows to write I/O drivers in user-space and feed the data from
+	the device into the kernel. The kernel parses the HID reports, loads the

+	This driver cannot be used to parse HID-reports in user-space and write
+	special HID-drivers. You should use hidraw for that.
+	Instead, this driver allows to write the transport-layer driver in
+	user-space like USB-HID and Bluetooth-HID do in kernel-space.
