Synopsis
Name: AutoSetup
Minimum usb8x version: 0.05
Sets up the attached USB device.
Inputs
- DE: Address of callback routine
- HL: Address of temporary buffer for descriptors
Outputs
- NC: Success
Destroys
- AF, BC, DE, HL
Notes
AutoSetup completes the following tasks:
- Checks for an attached device
- Calls HostInit
- Sets configuration
- Sets up pipes
AutoSetup may fail some circumstances, including devices with multiple configurations and/or interfaces. If you are using the U_CALL system, you don't need to set the callback address when calling AutoSetup. The address you set via U_CALL_INIT will be used instead.
Example
ld hl,DriverBuf
U_CALL DriverInit
ld hl,DescriptorBuf
U_CALL AutoSetup
jp c,Error
;Device is now ready to use
;Use GetClass or GetIDs to make sure you have the right device
