Module

A simplified and internal development version of SceUsbSerial:

  • Does not check SceSblACMgrForDriver for processes capabilities.
  • Does not check sceIdStorageLookupForDriver(0x112, 0, /*s_data_81003184*/ "", 0x40); (might be Driver name similarly to PSP IdStorage)

This module exists only in Non-secure world. The SELF can be found in os0:kd/usbdev_serial.skprx.
