I tried the new code and it works better. But I still don't
get the disk itself. Any ideas?

umass0 at uhub0 port 1 configuration 1 interface 0
umass0: ASAHI PENTAX PENTAX OPTIO 430, rev 1.00/10.00, addr 2
umass0: using ATAPI over CBI with CCI
atapibus0 at umass0 channel 0: 2 targets

So there is no "sd0 at atapibus0" visible. Here is my old mail:
