When I hook it up to the computer the PSP says USB mode as if it is connected. When I go to control panle I and then to Portable Media Devices it doesn't detect it there either. I turned off the computer 2 times and it still doesn't detect it even while the PSP says the 2 are connected. The OS is Windows XP and I haven't realy done any changes to it lately. I did have a trojan yesterday but I don't think that was it because the trojan had nothing to do with memory stick drives. I fixed the virus I think. Well, it says it is infected from when I fixed it but it appears to working fine. other than this but like I said I don't think this is beacuse of a viruse because it works with other devices it recognized as removeable device.
Sorry for bad grammar. I am in a rush.
