Synopsis

Name: MouseInit

Minimum usb8x version: 0.11

Initialize mouse driver

Inputs

  • DE: Address of temporary descriptor buffer
  • B: Flags
    • bit 0: set = allow diagonal keys, reset = disallow
    • bit 1: set = use passthrough callback

Outputs

  • NC: Success

Destroys

  • AF, BC, DE, HL

Notes

Important: The mouse driver inputs changed starting at version 0.11 of usb8x. Be sure to use [[../../GetVersion|GetVersion]] to check that 0.11 of higher is installed before using the mouse driver.

Initializes the USB host but assumes the USB driver has already been initialized with [[../../DriverInit|DriverInit]].

If you indicate to pass callbacks through, the callback address specified in U_CALL_INIT will be used if the U_CALL system is being used. Otherwise pass the callback address in register IX.
