This VID:PID is probably used in many PowerCOM devices, to give older  
RS-232 designs USB connectivity. A neat solutions, as long as there  
are drivers to create a /dev/ttyUSBx port on the host. But of course  
it won't tell you anything about the underlying serial protocol that  
is used. Powercom seems to have used both 'megatec' and what we now  
call 'powercom'.

Someone posted a usbsnoop log file to this list (for the same ULT33046  
type) on Jan 2nd this year. This very much looked like the protocol  
that is used by the 'powercom' driver, so I think this should be the  
correct one.
