I did it:

ugen1.2: <GF-500 EZZE-E800GF> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON

  bLength = 0x0012
  bDescriptorType = 0x0001
  bcdUSB = 0x0110
  bDeviceClass = 0x0000
  bDeviceSubClass = 0x0000
  bDeviceProtocol = 0x0000
  bMaxPacketSize0 = 0x0008
  idVendor = 0x0e8d
  idProduct = 0x0002
  bcdDevice = 0x0001
  iManufacturer = 0x0002  <EZZE-E800GF>
  iProduct = 0x0003  <GF-500 >
  iSerialNumber = 0x0004  <53923610014483f>
  bNumConfigurations = 0x0001

And I created attached patch but nothing different happened,
when I plug usb in, the same result.

Thanks
