[ltp] is there a way to mount an encrypted USB drive?

[linux-thinkpad@linux-thinkpad.org]

The thinkpad BIOS supports hardware encryption, but it only prompts
for passwords on SATA-attached drives.  It does not find USB-attached
HDDs that have hardware encryption, and does not prompt for a
password.  How can these drives be mounted?

There is a TPM project called "trousers", but the documentation is
vague.  Can trousers be used to mount a USB-attached
hardware-encrypted device?
