4 years ago I think it's: a) an issue with pygatt (and should be raised at their repo) b) an issue with your BT adapter. Does it support BLE?

3 years ago I have a very similar output on Linux Mint. I am using BT v5.0 (HCI, LMP=9.x and VID=0A12 PID=0001) generic/cheap dongle on my desktop computer. Was the original problem solved? Is my best chance to get it to work that I buy a BLED112 dongle? (When I tried to run muselsl on Win7, it clearly said "pygatt.backends.bgapi.exceptions.BGAPIError: Unable to auto-detect BLED112 serial port")
minus@linuxmint:~$ sudo muselsl list
Backend was 'auto' and bluetoothctl was found, using to list muses...
Searching for Muses, this may take up to 10 seconds...

Hello, I keep trying to stream data from the Muse to my desktop but after setting root privileges for hcitool as in the common issues, I get the following error when running the "list" command. I have tried reseting ym bluetooth adapter in every known way and still have no luck.
