Error code list USB Status Tests : DW-43

Hi RigoAguilar:

What issues are you experiencing with your Bluetooth connectivity, and have you run the Bluetooth troubleshooter built in to your Windows OS (e.g., Settings | Update and Security | Troubleshoot | Additional Troubleshooters | Bluetooth)?  Additional troubleshooting steps are outlined in the Dell support article Bluetooth Not Working? Solve Pairing and Detection Issues.

See my 22-Apr-2025 post in KeokiXPS's PCI Bus : Driver Error about these "for information only" Dxxx and Wxxx analytical notations that sometimes appear when SupportAssist runs a hardware diagnostic, which are not true error codes (and in your case, probably unrelated to your Bluetooth problem).  As suggested in that post, run a proper F12 ePSA (enhanced Pre-boot System Assessment) Quick Test hardware diagnostic from your BIOS as instructed in the video How to Run Dell ePSA, followed by Advanced Diagnostic Tests of your PCIe Bus, USB Devices, and Bluetooth (if offered**). If any of these ePSA scans generates an error code post back with your results.  If your ePSA scans don't detect a problem then it should be safe to ignore the DW-43 notations from SupportAssist.

** NOTE: The advanced ePSA diagnostics for my Inspiron 5584 BIOS do NOT include a separate test for Bluetooth.

If you require further assistance with your Bluetooth connectivity please let us know the following:

Has your Dell service warranty expired yet?

What is your Windows OS [open a Run dialog box (Windows key + R) and enter winver to find the version and OS build number] and BIOS version.  To find your current BIOS version open a Run dialog box, enter msinfo32 to open your System Information, and look for the field named "BIOS Version / Date" in the summary.

What is the make / model and current driver version of your Bluetooth device listed in Device Manager, and does the General Tab of the device properties show "This device is working properly"? Does your current Bluetooth driver version match the driver version recommended on your Alienware Aurora R12 support page*** at https://www.dell.com/support/product-details/en-us/product/alienware-aurora-r12-desktop/drivers?  From my Inspiron 15 5584, which has a Qualcomm QCA9377 Bluetooth device:

***NOTE:  To find the recommended hardware drivers that match your system components click the blue "Identify Device" button on your Alienware Aurora R12 support page, enter your unique Service Tag, and select the "This Device" tab on the Drivers & Downloads page.

@lmacri​ Hi, my bluetooth was not discoverable. I ran the Bluetooth troubleshooter and it did not find a Bluetooth peripheral on my desktop. But it came with bluetooth🤷‍♂️.

When I would go to Device Manager, Bluetooth did not even show up on the list until I chose "Drivers by type" on the View menu. The weird thing is that there was an error, some "unknown USB device" on the Device Manager list for USB serial port controllers. 

My Dell service warranty has expired 😢

I have updated all my drivers, including my bios through Support Assist. This problem still persisted.

Anyways, I want to let you know that today I decided to open my Alienware Desktop to see if my wlan was seated properly. Everything looked good. I even unscrewed the retaining screw for my wlan and removed it. Everything looked good. (Notice the emphasis😅) I put everything back together, and lo and behold, my Bluetooth was working again. I guess my WLAN needed to adjust the contacts on the card with the PCI port, or my WLAN card may be bugging out. Either way, I'm going to save another card in my Amazon cart in case this happens again.
