RingCube Technologies, the Mountain View company that sells the “MojoPac,” which is a software to store a virtual PC in your pocket via a USB device or iPod, has raised $12 million in a second round of financing.

VentureBeat first wrote about the company here, and later about the MojoPac’s choppy debut. But the company’s chief executive says those problems, related to some original restrictions the company placed on USB drive usage, have been resolved.

The funding comes from Mohr Davidow Ventures and first-round investors New Enterprise Associates (NEA), bringing total investment in the company to $16 million.

RingCube will use the capital to expand into other regions, including South America, Europe, Asia, and the BRIC nations. It will also seek to serve corporate users, allowing employees to carry a virtual private network product on their MojoPac device, so that they can access their corporate networks from other machines. In places like Brazil, China and India, for example, many people use Internet cafes or kiosks, and the MojoPac is a good way to store their data, said chief executive Shan Appajodu.

MojoPac launched in September, and has since seen tens of thousands of users, he said.
