Gentlemen,
I'm new to bitcoin mining and bought a new r-box 110-130 just 2 days ago. I downloaded and installed the usb driver using zadig, and installed cgminer 4.8.0 and just started mining!
The problem is hashing speed is hardly reaching 2 G ( yes .. with average of 0.75 G).
The cgminer.conf shows as the following:
{
"pools" : [
   {
      "url" : "stratum+tcp://eu-stratum.btcguild.com:3333",
      "user" : "Osama3agag_1",
      "pass" : "12345"
   },
   {
      "url" : "stratum+tcp://stratum.bitcoin.cz:3333",
      "user" : "Osama3agag.worker1",
      "pass" : "54321"
   },
   {
      "url" : "stratum+tcp://stratum.btcguild.com:3333",
      "user" : "Osama3agag_1",
      "pass" : "12345"
   }

}

and the result is:


Any ideas will be highly appreciated.
Thanking you in advance.
