Possibly yes. That IDC connector is basically just the same electrical connections but just in a compact connector for motherboard connection use. Just look at this image taken from this Amazon listing for a, StarTech USB A to USB Motherboard 4-Pin Header F/F 2.0 Cable, 6" (USBMBADAPT):

Note the exposed wires as well as the text on the motherboard header connector. That’s your big clue! So basically if you wanted to clip off the connectors on your device and wire them to a male USB that could be done as long as you match data and power wires correctly.

And if you are afraid of doing that yourself, you could purchase this: “Adapter Cable, USB 2.0, IDC 5 Male (single row) to USB A Male”:

And as the description for the product states:

Used to connect devices designed to plug into USB motherboard header pins to an external USB 2.0 connector

That’s actually a neat tool because you can now use the device as you wish without having to mangle the cable; just plug the female IDC connector into the male IDC connector and bingo! You have a USB device.

But since your device has 10 connectors you would need two of those cables to make that reader fully work. It could be that one connector has certain media reader slots and the other handles others; so maybe scoring one cable and experimenting might be the way to go.

EDIT: An addition, but here is a cool image of how someone was able to use one of those male male IDC motherboard header connector cables to connect to a USB flash drive with a broken connector. This shows clearly what all 5 connectors are: 2 are data, 2 are power and 1 is for the grounding/shielding.

Any recommendations for a 9-pin joystick to USB adaptor?
I rewired the micro switches in an old 9-pin speedking through one of those zero-delay usb encoders. Zipsticks are small, so you would have to do it externally. Then again, you may not want to hack a perfectly good joystick up? More on reddit.com

USB 2.0 case cable mismatch with motherboard
Sound like the cable from your H9 case is correct. The USB 2.0 header always has the bottom right most pin missing/blocked. Looking at the images for the your stealth x870, the headers on the back of the motherboard should have the bottom right pin missing. More on reddit.com

Can a DB9 connector be used as a usb connector
For LS/FS it does not matter, it will work. For HS, it depends on how you wire things up to the connectors. If you plan on also using standard cables, then it may be unstable. If the cable will be actual USB cable just terminated to a different connector, it will likely be fine. And absolutely no for anything USB3. Given that it is a keyboard, it will likely be FS.
