I brought a HDE keyboard:
Connects to your 7" tablet via USB 2.0 A-Type Male Adapter. Please make sure your tablet has a USB Type A Female to accept this plug type. Also, your device must have a USB host in order for the keyboard to function. Please consult the manufacturer of your tablet for those details.
for my Kindle Fire 1st Generation. I got the adapter to connect the A female to USB micro on the Kindle. Of course I didn't read all the through on this one, because I now need to have a host USB connection in order for the keyboard to work with the Kindle.
Any advice or do I have to ditch the keyboard and mark it as a bad deal?
