Unknown Device Issue Overview:
Device type: Other devices. Manufacturer: Unknown. Location: on PCI Express Root Complex. No idea what this device might be or if it's related to my performance issues. Should have made a list before upgrading. Now (again, too little too late), I check Dell's website - for drivers. They have no plans to support Latitude E4310 with Windows 10. Latitude E5470 with Win10 64bit has an unknown device: ACPI VENDELL&DEVABC6 ACPI DELLABC6.DELLABC6. That would be the Dell WLAN Radio Switch Driver www.dell.com. It has Windows 7 64 bit Professional installed on it. All the devices installed properly except one unknown device that I have not been able to find a suitable driver. Even after using the the Dell support software I have not been able to find a driver.
As long as there is a device not working on Windows 10, not recognized or incompatible, you may notice this device displays as unknown device with a yellow exclamation in Windows 10 Device Manager.
For instance, after you plugged in the USB device, your USB mouse or keyboard doesn’t work at all and when you check it in Device Manager, there are one or more unknown devices showing under Other devices branch in Device Manager.
In short, this unknown device Windows 10 issue comes up due to mainly two aspects, the one is that Windows 10 can’t detect the hardware, not to mention to find the driver for the device, and the other one lies in that the device driver is incompatible with Windows 10.

On a recent Windows 7 deployment project, I was working on integrating the device drivers for a Dell Latitude E6400 laptop and came across the dreaded ‘unknown device’. First, let me take a step back and explain the approach I use when it comes to managing device drivers. I usually try to keep driver packages to a minimum since I typically work with customers that have locations spread all over the place, connected by very slow links and no local distribution points (think Nomad).
One of the first things I do when working on the drivers for a new hardware model is apply the base Windows 7 image without any extra drivers. This allows me to keep the driver package as small as possible by using the Microsoft drivers that are included with Windows 7 when possible. I usually make an exception for certain drivers – network drivers being one of them, where I use the drivers provided by the OEM (in this case, Dell).
After applying my base Windows 7 image, I see two device bangs – one for Broadcom USH and the other for the ‘Unknown device’:
Now usually identifying devices on Dell systems is pretty easy since they are pretty good about their driver downloads on their support site. However, every now and then there may be a driver that you need that is buried in one of the Rxxxxx packs and filed under a category that you would not guess in a million years. One method of locating the driver is to download the driver CAB file (look under the Systems Management section), expand the CAB file and let plug and play figure it out.
This method works just fine for the Broadcom USH device shown above and will work with ‘most’ other devices that show up with missing drivers. The exception in this case is the ‘Unknown device’. The reason for this is because the driver for this device is not included in the CAB file. Part of the reason is that Dell does not have a Windows 7 driver for this device (USBVID_413C&PID_8149&REV_0100). However, if you look under the Windows Vista device drivers under the Network section, you will see a device listed called Wireless 410 UWB – that is the driver that you want to download and use. Once the device driver is loaded, you will see it identified as Dell Wireless 410 Wireless USB Device and Dell Wireless 410 Wireless USB Host Wire Adapter.
