Hi Tony,
I operate also an ASTRA 2200 su. I gave a try to connect to USB, what eventually did a kind of work, when:

- 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 to have connection only via libusb

But I continued to run into problems when doing a couple of scans one after the other (see archives for details). So, I went back to SCSI which works still fine. SCSI driver is loaded during boot, and a small script adds an entry to /proc/scsi/scsi before xsane is called (scanner is usually switched off).

Sorry for not having better news.

Cheers,
Klaus
