[Perasite]

I've got CM7 installed, it was easy enough to do. I'm trying to get Pershoot installed and I'm running into an issue. When I plug in the USB cable from the Gtab to my computer, it doesn't mount the internal card. The stock rom would pop up a box asking if I wanted to mount the card, but CM7 doesn't seem to. How do I get access to copy files onto the device's internal memory in CM7?
