Here how it goes
Ok I will help ya since I too recently bought a dell truemobile 350 bluetooth card from bal.....
1. install card
2. boot windows...
3.after windows installs the "windows bluetooth drivers" go to your device manager (right click on my computer, go to properties, then hardware, then hardware)
4. Remove all bluetooth drivers should be 2 entries I believe.
5. go to C:\Windows\Inf (you may need to enable show hidden files)
6. change the name of the following files from " Bth.inf " file to " Bth.inf.old " and " Bth.pnf " file to " Bth.pnf.old "
7. Restart
8. Install the newest dell drivers (the 11-XX... whatever file you have)
9. Go to control panel remove the dell bluetooth drivers from the add/remove programs list
10. download the widcomm drivers from here
http://www.megaupload.com/?d=BJ0NDHW6
11. Download Patch after you have downloaded the above file from here
http://www.megaupload.com/ru/?d=HKH6KNHJ
12. add the files from the patch to the same directory as in the widcomm drivers.
13. install widcomm drivers.
14. Reboot
15. Enjoy
Note I have done this and it works but I myself had too many drop outs from my 2200b/g wireless card with the widcomm drivers so I switched back to the newest dell drivers and have had no drop outs since.
P.S. Thanks bal for you help with getting my new 9300 up and running I will be seeing ya soon to get that 7800GTX...Gonna Be Freakin' Sweet!!!
