My desktop host has an Asus Prime X470-Pro motherboard and USB3.x ports on the rear panel plus two on the front panel.
I have a 7-port USB3.x hub connected to one of the rear ports. The external backup drive, Palm TX sync/charger, and the Nokia phone charger are connected to that hub. But, when I connect the Canon Canoscan LiDE 400 to the hub neither 'scanimage -L' nor 'sane-find-scanner' sees it. Connecting the scanner to a front port results is different: $ scanimage -L device `pixma:04A91912_4301BD' is a CANON CanoScan LiDE 400 multi-function peripheral $ sane-find-scanner ... found USB scanner (vendor=0x04a9 [Canon], product=0x1912 [LiDE 400]) at libusb:001:098 This series of Canon scanners is now supported by sane-1.0.28 which I built from the source code in a clone of sane's github repo. I don't now know which flavor of USB3.x powers the hub and front port and wonder why this would make a difference in sane (and I presume xsane) finding the scanner.
