Ok, let's try this: 1. Connect your device and don't worry about recognition or not 2. Open device manager and wait or scan until you see the mobile connections under networking 3. Uninstall ALL of them (any number) 4. Once you are done, disconnect your device and keep it disconnected 5. Uninstall WMDC and all variations of the device manager like sync and this and that 6. When you are done, go to the C:\Windows\Inf and remove winmobil.inf and winmobil.pnf files if they are still there and in safe mode command prompt, delete INFCACHE.1 (it won't let you do it in windows but you can try) 7. now reboot all fresh and don't open any application preferrably, especially outlook or any other application you are sycing with and install the WMDC latest version that you got 8. when done, REBOOT first BEFORE you connect your device 9. when up and running, open the application you want to sync with, like outlook or whatever and then minimize it and connect your device (ALWAYS VIA USB ON THE FIRST PAIRING) and make sure that your WMDC setting is set to allow USB, uncheck the bluetooth option right now, then select automatic and then check the two connection and authentication ones. 10. let it detect and then you "MIGHT" have to disconnect and reconnect or your might be able to pair right away. A few notes: Make sure your firewall has ActiveSync ports open or allows them, or it wonm't work. Also make sure if you are on a private network 192.168.1.x that you have DHCP enabled because when you connect your device you actually get a network adapter put in your network connections section that tries to get an IP. WMDC uses TCPIP for syncing unlike the ancestor ActiveSync and that will eventually become the only way. This will need an ip and if no DHCP then it will fail. Although it is supposed to fall back on old cable protocol if no ip, sometimes it does not which blows. good luck.
