Looks a lot like an issue that occurs only on my ryzen desktop, and not
on my Intel laptop, any ideas?

Title:
  CSR Bluetooth driver: Insufficient performance compared to WIndows
  driver

Status in linux package in Ubuntu:
  Confirmed

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

   Manufacturer: Cambridge Silicon Radio (10)

  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
