9-Pin USB Motherboard Male Header to Single USB 2.0 Type A Male Cable 7.8inch

needed for dell business pc without wifi, needed for power for the bluetooth on a wifi card

I don't get these OEM's who insist on straying from standards and don't include the usual headers on the motherboard, but whatever... it is what it is. Case in point, the Dell XPS 8930 I use for a HTPC. I added a wifi/bluetooth PCI card and although wifi goes over the PCI bus, the bluetooth needs USB and expects to use a header on the motherboard. Well drat, Dell doesn't add those in usually. This thing came to the rescue... it's goofy to have to route the USB cable out of the case and into one of the rear ports, but it works, and now I have WAY more reliable bluetooth than the flaky one included on the computer (it has a habit of "disappearing" for no reason until you remove power for a few minutes...known issue on this Dell model). So, if you need an internal USB header but don't have one, this will do the trick.

Quality product. Allows one to plug in SD Card readers or other accessories into a standard USB 2 or 3 port if there are not enough USB headers on your motherboard.

I installed a Wi-Fi 6 PCIe card in my HP Slim Desktop S01-pF045xt, and the card has a little Bluetooth header cable that has to be plugged into a USB 2 header on the motherboard to utilize the card’s Bluetooth function. I purchased the Wi-Fi 6 card knowing that I didn’t have a USB 2 header on my motherboard. Losing Bluetooth was a sacrifice I was willing to make for the increased Wi-Fi speed and performance that came with the upgrade to Wi-Fi 6. But thanks to this little cable I didn’t have to sacrifice Bluetooth. I didn’t even have to drill a hole in the back of the computer or remove any slot covers because there was a space in the back of the cabinet that was large enough to put the Bluetooth header cable through. My computer has four USB 2 slots in the back, and they are right under the space that the Bluetooth header cable went through. Bluetooth works great powered by an external USB port using this cable!

The standard USB header contains two channels (so two D+/D- pairs). The product page when I purchased this said only one of those pairs was connected, but when I tested the product I received with a multimeter, *both* pairs were connected. This might increase compatibility for single-channel devices, but if whatever you are connecting to actually uses both USB channels, this cable will short them out, yielding bizarre results at best, system reboots/other serious problems at worst. Still 4 stars because the cable is built well, with heatshrink and glue securing the wire bundle, etc. Just don't trust the product listing when it comes to the pinout description!

Good

Had to use as a work around due to having no unused usb connectors on the motherboard and no easy way to free up one. It worked as easiest way to connect new wifi / bluetooth card (TP-Link WiFi 6E Intel AX210 AXE5400 PCIe WiFi Card) to an outside usb port for bluetooth to work.

Only leaving a bad review because the description is misleading. It says: "Note:Only the bottom 5 pins are wired to the USB connector intended for single USB connection header devices." This is a lie. Both the bottom 5 pins AND the top 4 pins are wired, and they are both shorted together. This difference matters because you might be tricked into thinking that devices that require two USB lanes would still at least half work with this cable, but instead you will just short out the device and get USB errors. If you bought this hoping to use it for such a purpose, you will be out of luck, unless you want to cut open the cable yourself. If you cut open the cable, you can manually cut the black wires shorting the two lanes together. If you want to be real crazy, you can cut open a second USB-A cable and solder its four wires to the black wires and then you can have two functioning lanes.
