Hisense Sero 7 Pro: computer doesn't detect it topic

I just got a refurbished Hisense Sero 7 Pro from Newegg. It works fine except when I try to plug it into my computer via USB nothing happens. It doesn't detect it, try to install drivers, nothing. I have gone into the settings and turned on USB Debugging via the developer options. I also tried several diffent cables to no avail My computer does detect my Galaxy Nexus phone with no problem. Can anyone help or am I boned and need to send it back?

[Q] Installing a Nexus 7 rom on the Sero 7 Pro? topic

So, my question is just what the title says. It's probably an incredibly stupid question, but i'm curious nonetheless.

Everyone keeps saying that the Hisense Sero 7 Pro has hardware that's basically identical to the Nexus 7 (grouper), besides the sd card slot, and I was wondering if it's possible to install a rom that's meant for one, on the other.

The main reason I ask is i'd like to install AOKP, PA, or even Ubuntu Touch on my Sero Pro, but I can't find a way to do this.

Even if there are roms that I haven't found yet that work on the Sero, I'm still curious about my original question... :)

Thanks in advance!
