It is working now. Still waiting for the next hang

hopak-jj) ucm sh dev

Bus 0 (OHA0)
     Root Hub               - 2 port(s)
     1.0.0.0.0.0 -> DNA2    - Western Digital My Passport 2626

I will repeat this when it actually hangs


UCM SHOW EVENTT shows only the normal messages at boot time, but nothing 
at the time of the hang.

SYS$SYSTEM:USB$UCM_DEVICES.DAT: (currently the Western-digital is 
connected, The seagate I used previously gave the same problems)
