USB 2.0 Controller

  • NET2272 USB 2.0 Peripheral Controller (rev.1a) (557k .pdf) (alternative location: of that URL)
    • The NET2272 supports Microsoft’s Media Transfer Protocol (MTP), which allows playback of WMA and WMV files with Digital Rights Management (DRM).
    • PLX also provides device firmware supporting the USB Mass Storage standard. This means that PCs can recognize these devices without additional Host drivers.
    • Net2272 is a USB-function device, and as a result is a slave to the USB host.
  • It seems the Gp2x F-200 use diferent chip (GL827)to control USB that doesn't support USB networking (or any other gadget drivers).
