Notes

AutoSetup completes the following tasks:

• Checks for an attached device
• Calls HostInit
• Sets configuration
• Sets up pipes

AutoSetup may fail in 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
