I have OEM 7 inch Allwinner A10 based tablet with miniUSB connector.
When I plug in usb device, it *may* mount it then after a few second unmounts it, I've tried several flash drives, sometimes I get more or less stable connection then if I move the tablet a little bit, same mount/unmount sequence happens.
There's a similar problem with wifi card (which is based on the same USB controller according to USB Host Controller utility app).
When connected to the PC via the same miniusb port the connection is stable.
Android version 2.3
