USBLib_SelectInterface (SWI &5635D) — Selects an alternate interface on a device.
| R0 | Device reference |
| R1 | Pointer to waiting template |
| R2 | Interface number |
| R3 | Interface setting required |
This call selects a alternate interface configuration. The waiting structure passed will be modified by the call and must not be used again until the call has been completed. This differs from the request start calls that use the passed waiting handle as a template.
This call is implicitly performed selecting the first interface when the device is started.
