Tablet USB problem

    Hi. I have an 7" Touchmate e-Tab TM-MID780 tablet with android 4.0.3. The problem is the USB port doesnt detect anything except for the mice that came with it. Now, I cannot connect a flash drive, a 3g dongle or anything that goes into the USB port for that matter, even though the box says it supports all of them.
    Is there anything I can change or modify or add an app to overcome this problem. I'd truly appreciate your help guys.

    Is your USB flash drive formatted as FAT or FAT32? It won't work with NTFS formatted drives. And what make and model is your USB 3G/4G modem? It should support certain Huawei and ZTE modems, like the Huawei E220 and 1750. It should state in the tablet's instructions, as to what is and isn't supported.

    Thank you. Yes I did the factory reset but to no success. All my Flash Drives are FAT 32. The Dongles are Huawei EC152 (Tata Photon+) and ZTE 3G dongle (Reliance 3G).
    The thing is the microSD slot in the tablet detects the microSD card. But if I put the same card in any of the dongles' MicroSD slot it doesn't detect at all. Says "USB device has been unmounted". Do you think there's a problem with the USB port? But again the mice that came with it works fine.
