You should be able to use one of those sold in MI at Maylong web site cost $25 bucks. Looks like this. Ships for free by UPS Ground takes 2-3 days to get it.
The MID7015 came with an adapter for mini-USB to regular USB. Use most any keyboard with a regular USB plug. I've used a wired Dell and a Logitech wireless. We're shopping for a flexible keyboard (rolls up, silcone like material) for less than $10 at Amazon. Anyone tried one yet?
I purchased two of the 7 inch keyboards with mini USB from Euogo. The Coby 7015 has a telechip TTC8902 in it and that was one of the specs of the keyboard. They offer standard usb and mini usb which ever you choose. I placed my order on Jan 10th and received them on Jan 25th. I know you didn't ask, sorry Anyway, plugs directly into the Coby 7015 since it is mini usb and it works great. Also, here is just some extra info, I measured the case and it is about 8 15/16" h by 5 7/8" w. My Coby does fit nicely in the prongs.(just like our original case) Just know that since the case is longer, once you position the Coby you will have about an inch on each side of the tablet. In closing, it is really nice and looks good. Once I am done, I would fold the case up and throw it in my purse. I hope this information helps anyone interested in this keyboard.

Found maybe the same Euogo keyboard on Amazon too Amazon.com: LEATHER KEYBOARD CASE FOR 7' TABLET OR EPAD: Everything Else Do these have side bars or does the Coby fall out if you tilt it to the side? $25 + 5.50 I think we'll probably try it.
This appears to be the same with standard usb..if it is as the post above mentioned you would probably use the mini to usb adapter that comes with the Coby. Also, it appears to have the three prongs to hold the tablet in place. By the way, my tablet hasn't moved yet. Enjoy yours like me! Sent from my MID7015 using Android Tablet Forum App
I just googled "mini keyboard case" and came up with this: Portable Case Skin Cover With Mini Keyboard For 7 Inch Tablet PC - Protector Sheath(SMQ5852) - US$ 22.99 It's a couple bucks cheaper and down at the bottom, there is a Q&A and specifically about coming with a mini USB (it does). Okay, I'm a bargain shopper...here is is even better w/free shipping: http://www.buyelectronicstore.com/leather-case-usb-keyboard-for-7-inch-tablet-pc-mid-pad_p7071.html Buyer beware...I know absolutely nothing about this second source!!!!
