Hi Charles,
I operate the same type of scanner. Honestly, scsi interface works better with Linux (sane/xsane) as the USB interface. But due to comfort reasons I operate the scanner connected via USB (easier connect/disconnect) whithout real impact on functionality. The lesson I learned is:
- switch quality calibration off
- use only libusb, I have deleted scanner.o from /lib/modules or did compile the kernel without scanner support for USB at another machine to have connection only via libusb.

Cheers,
Klaus
