[LAU] sound with Scarlett 3rd Gen device?

[Iain Mott]

On the way to a solution:

The Scarlett is a USB 2.0 device. The USB ports on my laptop are 3.0. I 
tried the Scarlet on my desktop, first using the blue port (USB 3.0) and 
had no success. Later trying a non-coloured port (2.0?)and not before 
re-configuring the Scarlett in Windows (ie. simple connecting it), I got 
audio in and out to work. There are some audio glitches at both 
conservative and short latencies in Jack, but i'll worry about that later.

Can someone suggest please what I can do to get the USB 3.0 ports on the 
laptop to work with the USB 2.0 Scarlett? I checked the Bios and there 
doesn't seem to be a way to downgrade any of the ports. A software 
solution? I'm running Ubuntu 19.04.

Thanks,

Iain
