I recently had reason to reinstall the OS, etc, onto my Vista configured PC. Everything installed great until I tried to set up my Mobile PDA (HTC, XDA, Trion) via USB. Vista could not find the drivers, searched everywhere. Now when I plug the PDA in, the PC will not even see the PDA + memory card at all, looking through Device Manager also does not reveal it even as unknown device. I have possibly found Vista drivers for this PDA but without seeing the device in any form how can I get it to install them? Using another XP PC identifies the PDA straight away. Oh yes, before the reinstallation it did work to a certain degree. Any help please!!
