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

Works fine no issues

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 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.

If you have 2.0 usb headers on your motherboard that do not work, this is what you use as a work around. B550 mobos have issues with usbs as well probably just the 2.0 usbs so I plugged mine into a 3.0 and I don’t get disconnects either.

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!

I needed this adapter to use/power the Bluetooth feature on my Asus WiFi card. My sff dell motherboard didn’t have any internal usb ports. I was able to route the cables thru a small hole already part of the case and connected it to a usb 2.0 slot. Works perfectly!The adapter I received was the 2nd image, with the larger usb.

I ended up not using it but I did test it and it works as expected. Cable quality seems good but I can't attest to durability or long term use.

I ordered this to attach an external 2.5" card reader to a SFF build externally. It did not work, I'm not sure if this is a passive connection or how it can go from 2x USB connections on the 9 pin to 1x on the USB type A side. It seemed kind of odd but there were a lot of good reviews.After plugging in my card reader, the USB port on it had power enough to light up the LED on a flash drive. The flash drive itself was not readable. Plugging the flash drive into the same port on my PC, it worked fine. Plugging a SD Card into the card reader and nothing.I'm not sure if the adapter I received was just defective or if it is something else. I'll be returning this for a refund and just purchasing an external USB card reader.
