Connection is immediately lost

Hi, I just tried to connect, and the switch seemingly recognizes a new controller, but as soon as I try to send a command, connection is lost:

cmd >> [14:33:04] joycontrol.transport read::105 ERROR - No data received.

After that I get a NotConnectedError (which is to be expected I guess after losing connection):

cmd >> a

I did the --noplugin=input from #8. The readme states that I could also do this via USB, how would I accomplish that? If I disable bluetooth completely and connect my computer to the switch via USB, the script no longer works.

Thanks in advance!

Edit: forgot to mention, I am on Ubuntu 19.10 on a Thinkpad T480s

I was able to get my hands on a Raspberry and it works there, so the problem is probably due to the bluetooth on my notebook! I would still be interested in how to accomplish this via USB.
Thanks in advance!

Quick question: What version of Switch os, raspbian and bluez are you running on the pi and on the Laptop what version of bluez? (run apt-cache policy bluez for bluez version, should be in the range 5.5X)

Also if you really want USB, there are a few projects:

• https://github.com/progmem/Switch-Fightstick for I believe a Teenzy or really anything capable of running LUFA
• https://github.com/shinyquagsire23/Switch-Fightstick for a Arduino Uno R3
• https://github.com/Poohl/gadfetfs-Switch-Fightstick for anything running Linux and a USB device controller
  Note however these are not based on the Pro-Controller and thus have no NFC, Gyro, (maybe Rumble) etc...
