First, I'm using a PSP 3000 on 6.20 PRO-B6 CFW. Ok so a couple of days ago I couldn't get my PC to see the contents of my Memory Stick trough the PSP's USB, but at least it recognized it was connected and I could still charge it trough USB and use Remotejoylite. (Didn't bother me much at this point since I could transfer files by the my Pro Duo reader on my PC.) But then today, my PC fails to recognize the PSP at all. So I can't charge it trough USB or use Remotejoylite. I've already ruled out it being the USB cable's problem since I have 2 of these and none of them work. (While both working with my PS3 controller.) I've also tried different USB slots all over my PC and none work. Can anyone help me out on what they believe the problem could be?
