Scanner works, and does not

Hello All, An "interesting" scanner issue. I have been reading up on Debian bug reports, and there is similarities, but also differences. I am using Debian Buster, I think it is up to date, I can scan with Simple Scan, but not with scanimage from the command line. I have found the scanner with lsusb, the permissions look right, and looking at other bits, I cannot see any obvious fault. I have not had to add myself to the scanner group in the past, and it appears that may not fix the issue from reading. I would appreciate comments and suggestions. Regards, Mark Trickett
