The [http://www.nxp.com/ NXP] isp1707 is used as the USB PHY chip. [http://www.spinics.net/lists/linux-usb/msg25167.html].
 +
 
 +
There is no published datasheet for this chip.
 +
It may be available under another name.
 +
 
 +
It is not connected in a way which the direction of the USB port can be reversed.
 +
 
 +
This means that host mode is impossible without hardware modifications.
 +
 
 +
Reportedly connecting pin D3 (ID) to D2 (GND) of the chip will allow direction to be switched.
 +
However - this is a challenging rework job, even for those experienced with SMD soldering, and of course will void the warranty!
