Bluetooth not discovering some devices

I originally had an issue with my bluetooth device powering on. You can find that issue here: https://bbs.archlinux.org/viewtopic.php?id=279133
Now, I can power on bluetooth and initiate a scan. I have a logitech headset, an HP printer, and an 8bitdo retro controller which I'm trying to attach, however my bluetooth device isn't discovering any of these.
I have a laptop running linux which can discover the 8bitdo just fine, pair, and connect. It also sees the printer, and logitech headset. This while being on the desk on top of my desktop machine tower. My android also sees all of these devices.

What's really strange is there is a device advertising itself as LuPi, which my desktop sees and my phone sees.

So I don't understand. Why might my desktop not be discovering these devices? I cleared all the scan filters, but still no luck.

Just to compare, Here's the output of `sudo dmesg | grep -i blue` for my laptop, and then for my desktop.

And actually, now that I've had a chance to look more closely at these messages, I think this MIGHT be a driver issue? Any idea how to fix this?
