So it looks like it's just a common interference problem with USB 3.0,
sorry for that.
I got confused because on Windows it looks like the USB 3.0 device (hard
disk) I got near the bluetooth adapter is switched off until I open a
file in it, while on Linux it looks like it's always not, so it's not a
bug but an interference.
You can close this, sorry for bothering you

Title:
CSR Bluetooth driver: Insufficient performance compared to WIndows
driver
Status in linux package in Ubuntu:
Invalid
Bug description:
I'm reporting this because I'm pretty sure a class 2 bluetooth adapter
shouldn't be unable to connect at less than 1 meter, when comparing
this to the Windows driver at least...
The bluetooth device is a CSR USB bluetooth 2.1 adapter

the kernel driver in use is `btusb`
the ubuntu version is 19.04
the kernel version is 5.0.0-13-generic
In Windows this adapter work normally, on Ubuntu Linux it's barely
able to connect to any device and maintain a stable connection, it
completely loses the connection unlikely in Windows after more than 40
centimeters
Already tried the 5.1 mainline kernel, it doesn't seem different
Worth noting that I also tried this on my laptop, and here looks like
it works insanely better than my desktop pc...
My desktop PC has a Ryzen 5 1600 CPU, and an MSI b350 mobo
