Dell XPS 13 clean install & missing driver?

I just received my Dell XPS 13 (2015) QHD and immediately the first thing I did was perform a clean Windows 8.1 install.

I got all the drivers to work except for a device identified as bcm20702a0. Everything I've found online seems to indicate it's some sort of Broadcom bluetooth driver, however Dell's site only has a Broadcom Wireless DW1560 driver. Installing that driver doesn't seem to work.

Has anyone else run into this?

Thanks...

 

For bluetooth, I think I installed this driver: "Intel PROSet/Wireless Bluetooth LEGUI Driver" for the bluetooth to start working.

On a somewhat related note, I also reinstalled Windows and I have a bunch of missing drivers. http://imgur.com/Cc4tHO5

They're related to PCI and ACPI, there are a few more 'unknown devices' towards the bottom. Anyone else get this? I haven't noticed anything not working right but I've barely got the laptop.

 

I tried the Intel PROSet/Wireless Bluetooth LEGUI Driver and BCM20702A0 still shows up in the device manager with an exclamation point. I'm pretty sure before I did a clean install, I looked in the device manager and saw no issues, so I don't believe it to be a hardware issue. This is the only device missing drivers in my device manager.

 

It's Broadcom bluetooth (hence BCM), try this:

Tried those. At the end of the setup I would get an error saying Bluetooth stopped working due to compatibility.

 

Just to provide an update, here's what I did to get this working.

Downloaded Lenovo/Broadcom Bluetooth drivers: http://download.lenovo.com/pccbbs/mobiles/h9bn03ww.exe

1. Extract h8bn03ww.exe
2. Open Device Manager -> Update Drivers -> Select from disk -> Browse to C:\DRIVERS\WIN\COMBT\Win64\bcbtums-win8x64-brcm.inf
3. Select Dell DW1550 BlueTooth 4.0 LE. Driver installs successfully and detects my bluetooth devices!

 

For anyone looking for the exact drivers you need to install w/o having any missing drivers, here's my list.

These links are for Win 8.1/x64.

6. Intel Serial IO Driver
7. Intel Management Engine Components Installer
8. Intel Rapid Storage Technology Driver
9. Realtek CardReader Driver
10. Dell Command Power Manager
11. Intel HD Graphics Driver
12. Broadcom Bluetooth drivers (see my post above on how I got it to work on my machine)

 

Hi !

Anyone tried here to do a clean install, not with the Dell drivers but instead with the generic drivers provided directly by the manufacturer of the different devices ?

I used to do this before, with the help of a website ( http://www.touslesdrivers.com/) which has an incredible database of drivers, and a very neat detection tool, which detect all your hardware and provide you with the generic drivers, but their tool isn't working anymore .....

I loved this website because it was providing updated drivers, for example for wifi or video card long after the manufacturer of the computer stopped to provide updated drivers. Was perfect for old laptops, and very accurate, I never had an unrecognised device with this website.

I planned to do this the old way one day, by searching directly on manufacturers websites, but I haven't got the time to do it yet.

 

Dell may have made optimizations to some drivers to get the most out of the hardware. For example the Realtek audio driver from Dell's website includes an audio manager that makes the sound less shrewd/flat and more vibrant. So you probably wouldn't want to use manufacturer drivers for some things...
