i have been having trouble trying to use media sync with my bb 8300 curve. When i connect my phone to desktop manager it syncs connects the whole bit, when i try to use the media sync it tells me that i cannot recognise my device. I have removed and formatted my media card, i have tried to reinstall device software with no luck, can someone please advise me if there is a solution to said problem thanx crackberry forums!
I had the same problem. I set the phone not to use Mass Storage Mode because I never could get it figured out. There's a setting under Options->Media Card to set "Auto Enable Mass Storage Mode When Connected" to No.
I bought my Curve used, so I'm figuring that there's something wrong with the USB port.
