Dell OptiPlex 7050 Internal USB Header
I have an OptiPl;eax 7050 sff. Recently bought a combo wifi6-Bluetooth PCI-e. The BT functionality requires powering on so connected the 9-pin cable to the 13-pin onboard USB header. Having used every trick in the book I cannot for the life of me get the BT powered up through the 13-opin usb header despite various sources on google confirm it should be ok to align the 9-pin correctly inserted to the mobo header USB. I have also tested the card with my dual linux (on the same machine). The BT is simply not visible to the Linux either.
This is definitely not the question of driver etc.
Please help as I have run out of option.
Many thanks.
Rgds,
Bina

does your mobo has a silk screen that looks like this next to the INT USB header?

Many thanks indeed for your reply. I have exactly the same but without the QR sticker. I am attaching the photo.

it says BT so it should work. the top 9 pins match the USB 2.0 pinout. test your card in another pc to verify BT works.

<Profanity is never allowed. DELL-Admin>
Yes thats why I am pulling my hair out! Just to go the extra mile for you I installed the combo card on two other desktop Dell computer. An Optiples 4020 sff and XPS 8100 (15 years old). On both computers the OS instantly sees the card though they needed drivers installed but visibility in device manager. Also I dual boot in to my Linux Mint and with no additional drivers the WiFi and BT are operational. That being said on the same pc when I boot into Win10 (22H2) the WiFi works but BT does not exist no matter what. Anyway thanks for your time. I have given up on the thing. Have a nice weekend mate.
