-This tablet comes with a mini-AB port with true host/slave functionality. According to the devices specifications it should be an OTG port but if this is the case it's wildly out of spec as it can power up HDU units, internet 3G sticks and other stuff that is typically close to the 500mA limit on standard USB ports. +This tablet comes with a mini-AB port with true host/slave functionality.

The A13 has another USB port that is dedicated do the internal WiFi card.
 There's an article on [[http://en.wikipedia.org/wiki/Usb#Physical_appearance |wikipedia]] that may be useful to those wishing to make their own adapter for the mini-A socket to put the port in HOST mode. There's an article on [[http://en.wikipedia.org/wiki/Usb#Physical_appearance |wikipedia]] that may be useful to those wishing to make their own adapter for the mini-A socket to put the port in HOST mode.
  
-With the stock android on the device I've used successfully all sorts of devices without the use of externally powered hubs, but I cannot say the same with the linux-sunxi kernels (both the 3.0 and 3.4 series) where the only things that seem to work right are keyboards, mice and some storage devices. It's been several months since I reported the problem to the sunxi dev mailing list: I don't think they're interested in fixing it for the general public: it's a pity because this makes it pretty much pointless running custom linux images on this tablet, and probably many other Allwinner SOC based devices.+With the stock android on the device I've used successfully all sorts of devices without the use of externally powered hubs, but at time the linux-sunxi kernels make get broken OTG driver. In any case as of 3.4.75 I was able to get the USB Ethernet cards working on the OTG port.
