Hi all
I picked up a cheap bluetooth USB dongle, which refuses to work.
I've found a few posts in the HCL and other places that suggest that it ought to work. When I plug it in a blue LED lights up, and dmesg reports seeing it.
It is seen by hciconfig, but it's marked as DOWN, and refuses to be brought up or reset with an error of "Operation not supported (95)"
This is a T420 Thinkpad, but I've also tried in a Lenovo desktop which is probably about the same age.
I'm running slackware64-14.2 and I've tried the stock kernel (4.4.186) and 5.1.7. I also tested with a couple of alienBOB's live -current bootable DVDs so I could test on clean systems.
I also tried updated the bluez package to the latest git, and from what I've read so far firmware isn't needed for this chip.
It's not blocked in rfkill and I checked the BIOS and enabled all the ports.
hcitool dev and bluetoothctl don't list it at all.
Any ideas what to try?
Here's some bumf:

Thanks for any ideas to try to get this working.
