recent PCLinuxOS 2009.1 iso and repositary I believe is libusb 0.14

what about things like old eeePC's and older distrib's that do not auto/easily 
update ?

If not tooo painful support for both would be good, i.e. detect version and have a safe fallback ?
This may be outside scope, aim, or too much effort/bloat but if a short text could be displayed briefly along lines of
"libusb < v1 limited safe mode selected" ?
