My son wants to be able to use a keyboard with his phone on occasions so I purchased a couple of micro to female USB cables and plugged in the adaptor. I can see the adaptor has been detected by the phone but no go from the keyboard. Plug a standard keyboard in and works fine, even the led backlights work which surprised me, god knows what that would do to the battery life mind you So any tips on how to get this working? just checked the batteries which is the first thing I should have done but they are fine. The keyboard also works in my lounge pc but strangely not my main pc, that already has a wireless mouse so not sure if that's why but I'm not bothered about that anyway.
