Really? And I was tempted about replacing my MorphOS 2.0 "massstorage.class" with this new one...
I'm one of those shocked by a pendrive that doesn't work at all in 2.0, but worked perfectly in 1.4.5.
And what would that help? The problems were mostly related to pciusb.device and obviously that is not part of MorphOS for PowerUP. And this specially compiled version of massstorage.class for MorphOS 1.4.5 doesn't use the mount.library of MorphOS 2.0. And that's just one difference.
When I said you shouldn't use this version for 2.0, I had a reason.
