I'm not sure how much of this can be laid at the door of "USB", I think it is more specifically trouble with SANE backends.
I had wasted probably weeks trying to get my cannon FB630U to work under 2.6x kernels until some helpful sole suggested I try vuescan. This worked beautifully straight out of the box and produces better results that I had got with the sane backend when it did work under 2.4 I would like to work with open source solutions but there is a limit to how much time I can reasonably spend on a broken driver (and I have already over-stepped that mark by an order of magnitude. ) Emails to the maintainer remain unanswered. Big thanks to the guy who made me aware of vuescan. Regards to all.
