Support for USB devices seems to be limited comparing to other available emulators. Although PS2 side of USB subsystem seems to be fully implemented. IOP emulator in SPU handle USB HW registers addresses and generate interrupt for PPU which later handle RW to mentioned registers in similar fashion to ps2_emu/ps2_gxemu. PS2 side of things can be disabled/enabled using one byte, when disabled USB writes are ignored, and USB reads return 0. Initial state is unknown. Emulator seems to accept HID controllers and use them as DS3.

#PLAYSTATION(R)3 Controller (Vendor ID 0x54C, Product ID 0x268),

  0x06 - External interrupt enable (48 bit in MSR) with param 0x8000, otherwise do nothing.
      This sc is more like restore 48th bit of MSR, but many times emu use it to enable bit without using old state.
      Also, emulator panic LV1 if syscall is called while external interrupts are already enabled.
