Just for the record, after compiling a new kernel with fresh 6.0-current source 
the problem appears to be resolved on my Thinkpad T61.

/usr/ src/sys/dev/usb/usb_subr.c is revision 1.131 now. Thanks Martin, jsg@ for 
quick fix.

Yes, I have a similar issue on an X220, but for me it manifests with the
fingerprint reader, a ugen(4) device, and not with two types of umass(4)
devices -- both memory stick and dvd burner work fine.

It appears to me if I revert src/sys/dev/usb/usb_subr.c to r1.128, the
device problem is eliminated, so Martin is in copy for his awareness.
(He may already be aware, of course.)

Same issue, keyboard/mouse doesn't work after upgrading to Sep 18 snapshot. I'm
