   For sure someone will offer you a better advice.  Try, before connecting usb-3.0, something like this in the terminal emulator:

t='sleep 30'
a='dmesg|tail -n40 > dmesg.txt'
b='journalctl -xe > journalctl.txt'
eval "${t} && ${a} && ${b}"

and connect usb-3.0.  Then see if there anything interesting in those files.

it’s works, but in two o three try

it’s necessary install any driver?

Is there any errors reported in those files?

Especially bad due to that machine is system76’s.  Did you’d tested this USB-3 with the older releases?

not, today update kernel to 5.5.10-200.fc31.x86_64, its works now

not i need connect and disconnect two times

could it be that in this line:

eval "${t} && ${a} && {b}"

is a “$” missing and should read:

eval "${t} && ${a} && ${b}"

???
cause a test with

eval {b}

gives:

bash: {b}: command not found
