Sony Computer Entertainment America has filed a lawsuit against an online distributor that was planning to sell the new PSJailbreak USB modchip. Sony believes that the device circumvents the PS3’s copy protection as it allows people to back up and play games copied to the system’s (and external) hard drive.

The distributor in question is Zoomba LDC, and they have been accused of copyright infringement, violations of the digital millennium copyright act and trademark infringement. Sony is beginning to clamp down on the device, having recently got a temporary injunction that stops the PSJailbreak being sold in Australia.

However, it looks like the cat is out of the bag as clones of the device have already started to crop up. Inventive folk can even make their own with a teensy board or a few other USB development boards.
