R0 | current version of usb library interface |
R1 | Registration handle |
This call should be made by all clients of the library to obtain a registration handle. This is an unsigned 32 bit number used to identify a client. Although this call is not strictly necessary to use some of the functionality of the library it enables users to see all registered modules and prevents the library being quit while drivers are still using it.
