The most Micro USB to USB converters are not work if you want to use it for OTG converter, because the 4. pin of the micro usb plug is not connected!
The most ebay and computer shop's converters like this!



If you want to use it for working OTG adapter you have to connect the micro usb connector 4. pin to GND (5. pin).
Like this:


I made this mod on my adapter and it works!

First you have to open up the outter cover and carve the plastic around the micro usb pins. You can use multimeter to check the pinout.

After that solder the 4. pin to 5. pin with a piece of wire.


And finally glue back the outter cover.

So if you have not working adapter you can mod it, if you have suffice experience with electronic and proper tools.

Only do with your own risk!

Weird I got one off eBay from Hong Kong and it works without Modding. Can open files off a USB stick. Got it for £1 :)
