Hi @georgeoomment,
If you are happy to just be able to charge your tablet so that you can use it, it may be easier to purchase a wireless charger, (http://www.amazon.com/gp/product/B0041RRORA/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B0041RRORA&linkCode=as2&tag=thedigdig-20) than to find a replacement daughterboard (on which the USB connector is mounted) which is compatible with your particular model Nexus 7 2nd gen tablet or to replace the USB port connector itself. You will of course not have USB connectivity, but at least your tablet can be charged and be used.
