Bus 002 Device 001: ID 0000:0000
Bus 001 Device 005: ID 0781:5150 SanDisk Corp. SDCZ2 Cruzer Mini Flash Drive (thin)
Bus 001 Device 004: ID 0c0b:5fab Dura Micro, Inc. (Acomdata)
Bus 001 Device 001: ID 0000:0000

but only the SanDisk is being seen and is auto-mounted as
/UNIONFS/dev/ubb1 on /mnt/ubb1 type vfat (ro,nosuid,nodev,umask=000,uid=1000,gid=1000)

It's a 250Gb NTFS external drive...

How do I mount the Acomdata drive.

I did the usb2 boot toggle too!

Stumped..in Calif.
