This device to Arduino pro mini

Hi, I want to know is it possible to connect this device to arduino pro mini to have USB connectivity: http://www.ebay.com/itm/350568364250#ht_6408wt_1209

If it is possible to connect them do Arduino mini will require extra power or it will get it from "USB to TTL" device?

Yes - this works, I've used loads of them in projects, It will power the Pro-Mini at 5v(Vcc) or 3.3v

Thanks! This forum is not place for that but i think there are bug on Mirf.cpp. It not works on arduino software 1.0.1, but i have downloaded 0022 version and it worked with it. The issue is on code compiling process.
