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.
