I don't see how that would make a difference. I have 2 older HTC phones (Polaris/Excalibur) and neither of them have any issues accessing an SD card when connected. I tried disabling both my firewall and antivirus (ESET NOD32) and STILL am not able to connect my MyTouch 3g 1.2.
This is really starting to aggravate me. Someone surely has some sort of solution for this by now?? I know the SD card itself is working as I have used an older phone to copy some music to it for testing purposes.
Well I got it it work for roughly 10 minutes by reinstalling the PDANet software. As soon as I disconnected I am now back to the same situation as before. I really do not understand what is causing this. None of my older HTC WinMo devices have this problem AT ALL.
