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.)
