If there are USB 2.0 certified cables then they would be like Cat 5e and USB 1.1 certified would be like Cat 5.
So far as Cat 5 and Cat 5e will both run 100mbps, so both will run USB 2.0 but at 5e is higher quality and more future compatible...maybe anyway.
I have not read anything anywhere to say that it won't work.
