When I connect my PreSonus USB AudioBox 96 to my Ubuntu 18.04LTS desktop via USB2.0 port,
dmesg shows the following errors in a loop:

I suspect the failure is at this line of the linux kernel.
The interface is intermittently available as an input source in alsamixer. It will be available for a few seconds, then disappear, reappear, etc. The device works fine on my Windows machine.
Does anyone have any advice for how to debug/resolve this issue?
I've included the output of lsusb -v below.
