One week passed I have bought nokia E7 and from today it keeps on giving me notice that ‘’connect USB cable to device’’. I connected my Nokia E7 with my computer, it says “unsupported USB device. Disconnect device”. Then I tried connecting it to my charger it shows the same notice ''connect USB cable to device''. So I can’t charge the phone. Please help me! I am eagerly waiting for reply to solve it.
