I have confirmed this issue with another owner; the sytabex7-2 does not connect to a usb interface from its 2 usb mini ports. Can anyone else confirm? I've tried with and without the power adapter, both usb ports, different mini to a cables, different ports on the compo, tablet power on, off, menu + power at boot, menu + power + screen at boot, enabled USB debugging (which shouldn't matter). no avail. I have also tried with different ius's installed both stock and one from a synet7lp.
