Update: New USB circuit board finally arrived. After removing battery & doing Flea power release then disconnecting CMOS battery cable & repeating the power release again, I was able to uninstall the faulty circuit board then installed the new one. Next I booted into BIOS to reset to optimal defaults then after a quick reboot, both of the USB ports on new circuit board are functioning properly once again.
Hello community!  So I had purchased a new USB circuit board for my 2019 Alienware m17 R2 laptop because it has the Wireless Network card attached to it that I need to replace. Unfortunately the card is factory soldered onto the board hence the reason I'm needing the whole USB circuit board. Very easy to disassemble too. The one I purchased sadly wasn't the same part number as mine so I had to returned it for a refund with no time table when the right one would be available. No worries because the Wireless Card I'm replacing still worked, just wasn't getting the usual "full" Wi-Fi signal. I normally use Ethernet so no big deal...so I carefully re-assembled the circuit board back inside my laptop, connected the wire that goes to the board, reinstalled the battery, reconnected the laptop battery to main motherboard, put back cover on then turned on laptop. From there I'm prompted to go into BIOS to set default settings again and after rebooting I was back in business. Or so I thought. The Wi-Fi still works as it did before but neither of the two USB ports that are also attached to that circuit board work now...even after uninstalling/reinstalling all the USB drivers. So I have no idea why the ports are no longer working and I would really appreciate if anyone here in this very nice and helpful Dell Alienware Community could help me fix this issue. I've also attached a picture of what the circuit board looks like as well. Thank you all in advance for any solutions you may have in regards to this discussion. Have a good day.    [IMAGE]
