VR Driver Issues after Hard Drive Replacement

[zanebullsye10]

My PC's Hard Drive went caput a few days ago and after getting it replaced I can't seem to set up VR properly. What confuses me is the fact that VR worked swimmingly before with little issues, and yet now the Drivers that I'm missing I can't seem to find anything to do with.

It started with getting Error 208 on SteamVR, which usually just means that the Display for the Headset isn't found. However, after checking the Device Manager, I noticed that unlike before, there were 4 things under "Other Devices" that had the warning symbol next to them, as well as noticing that those four things that seem broken are necessary for VR.

The Devices that seem to not be working are as follows:
- BCM2045A0
- PCI Serial Port
- PCI Simple Communications Controller
- SM Bus Controller

I'm assuming that I won't be able to get VR running until these are fixed, and I can't seem to find many decent suggestions on finding their drivers online. The only fixes I've found are to Uninstall the USB Drivers so they reinstall properly, which didn't seem to work, and to try to install the latest Chipset (whatever that is, I have no clue) which only told me that it was incompatible with my PC.

Does anyone have any kind of suggestions on what I can try to alleviate the issue?

Here you go.

I've tried multiple times, the site keeps telling me I reached the posting limit.

Here, thanks for all the help by the way.

All I can tell you is to try this download from dell for the Broadcom driver:

Well that's annoying. Even the website doesn't help.

Then you need to discuss with dell, as that is not an intel driver and it is provided by dell.

Sadly no good, all Dell told me is to get a new computer. I disagree with that sentiment for the sole reason of the computer was WORKING on Saturday, and this is only occurring because I had to replace the Hard Drive. 

[AlHill]

Ok, let's try this.

In devicce mangler, uninstall the broadcom device, selecting the checkbox to remove the software.

Then, scan for devices and see if it reinstalls the broadcom device for you.

How do I scan for devices?

[AlHill]

Just right click anywhere in the device mangler and select scan....

Just like before Windows says that it gets it "Set up and ready to go," but it still has the warning symbol in the Device Manager next to it that says otherwise.

[AlHill]

Ok, you removed the "other device", correct?

Then, you scanned for new devices, correct?

It should have either re-displayed the other device, or it should have correctly installed it.

If it re-displayed the other device as before, there is not much I can do.

Dell has a support forum.  Perhaps someone there is more familiar with this on their hardware.

You need to install your motherboard’s chipset and device drivers, once that’s done, SteamVR should detect your headset and fix Error 208.

Download These Drivers from the Manufacturer Website

Install in this order:

:keycap_1: Chipset Driver (VERY IMPORTANT)
:keycap_2: Intel Management Engine (MEI)
:keycap_3: Bluetooth Driver
:keycap_4: USB Drivers (if available)

These will automatically fix,

• SM Bus Controller

• PCI Simple Communications Controller

• PCI Serial Port

• BCM2045A0

I have been in the same boat after swapping out a hard drive, it is super frustrating when everything worked fine before. From what you’re seeing in Device Manager, those warning icons usually mean your motherboard/chipset drivers aren’t installed yet. The VR headset itself is fine; Windows just can’t talk to the necessary controllers.

Here’s what I’d try:

Figure out your exact motherboard model – this makes all the difference for getting the right drivers.
Go to the manufacturer’s site (like ASUS, MSI, Dell, HP) and download the chipset drivers, Intel Management Engine, and Bluetooth drivers. That usually fixes the BCM2045A0 and PCI devices.
Install in order – chipset first, then ME interface, then Bluetooth. Reboot after each major install if needed.
Check Device Manager again – those yellow warning symbols should be gone.
Launch SteamVR – once Windows recognizes all devices, VR should detect your headset without errors.

Honestly, this is the most common issue after a fresh Windows install. It’s not broken hardware; it is just missing the system-level drivers that VR depends on. Once you get those installed, things usually snap back to normal.
