This is on an X64 Ubuntu 20.04 machine.
Any help would be appreciated.
Thank you,

Things to check:
Are you using a USB3-compatible cable---like the one shipped with the B205?
How old is your computer? Very-early USB3 controllers were flakey in
this regard.
Are you going through a USB hub, or direct to the computer? Some hubs
are, again,
flakey in this regard.
Are you running in a VM, or on "bare metal"? USB support in VMs
continues to be sub-optimal.
Can you try backing-out to UHD4.5 or even 4.4?
