Hi, Thanks for the replies. I ended up using a workaround described here: http://www.mail-archive.com/[EMAIL PROTECTED]/msg08209.html
Pieter changed the IBUF_SIZE in scanner.h from 32k to 64k. This seems to have done the trick for me. I looked in the 2.6 kernel code and it remains 32k however. Since this seems to be a fairly isolated problem (probably ohci/scanner weirdness) I don't think I'll pursue a patch or anything, unless this issue is more widespread. Hopefully will be moot once I grab an EHCI board.
