5 UHID allows user-space to implement HID transport drivers. Please see

9 With UHID, a user-space transport driver can create kernel hid-devices for each
10 device connected to the user-space controlled bus. The UHID API defines the I/O
11 events provided from the kernel to user-space and vice versa.
13 There is an example user-space application in ./samples/uhid/uhid-example.c
