E7450 - Unknown Driver ID INT3420

I have reinstalled Windows 7 Pro x64 on a new E7450. I have not used the recovery partition as I prefer to have a system fresh and clean.

After updating all the drivers from the 7450 download page, I have one more item in the Device Manager that still shows up as Unknown Device. It's hardware ID is INT3420 and I have no idea what it could be. Any ideas and ideally, a download link?

Again it's Windows 7 Pro x64, not Windows 8 or Windows 10. Thanks!

You are using old techniques on a new computer that could cause more problems in the future. Windows and all the drivers and factory software are not installed in pieces on today's computers. Instead a system image is used and the whole installation is a single image file which performs much better. You should use Factory Settings to return the system image. 

That ID number seems to refer to Intel Bluetooth--this web site came up by searching for that ID#

RE: E7450 - Unknown Driver ID INT3420

Thanks for the link, I'll give it a try. I must have missed it on my first pass of the Dell Download/Drivers site!

I never use the system restore disk as I despise all the Dell bloatware and branding that it includes. Once you get a checklist down for a fresh install and download all the drivers, it doesn't take long to get a system up and running from a USB image of the Dell Windows 7 SP1 DVD.

I'd rather have a system running with exactly what I put on it instead of what Dell thinks I should have on it. Nowadays I don't even boot into Windows when I take a Dell laptop it out of the box, I immediately hit F12 and boot to the USB disk and install fresh.

A few months ago I did a day-long comparison of two identical 7450's straight out of the box. After installing the applications that a typical user needs (Office, Acrobat, etc), plus joining to a domain, my fresh system booted faster, opened applications faster, and ran quieter and with lower CPU temps than the Dell factory-installed system. Plus I didn't have the Dell branding nor all the startup stuff, and I've saved 9GB of drive space (not counting the partitions that Dell ships with) over the Dell default image install.

I don't suggest this route is right for everyone, but it works great for me.

By any chance, could it be this driver?

Never heard or thought there should be anything wrong down the line with a computer one had installed on his own (if properly). I must be old-school.

RE: E7450 - Unknown Driver ID INT3420

Thanks for the link. Turns out it was the Intel Power Sharing Manager Device, whatever that is. I just had to extract the CAB file using 7Zip and right click ont he Unknown Device in Device Manager, then Update driver and point it to the location of the extracted CAB file. It figured it out from there.
