It should work with the bcmxcp driver. But there is something that
is missing.

Command Acknowledge block may be sent in response to any block request
if the data response is not implemented or temporarily unavailable.

And that situation is not handled by the driver at the moment.
It only take care of that when it knows it would get a command
acknowledge. 

Looks like the PW9315 PW9150 and Prestige9 use a slight different
protocol. 

The driver that may work is the genericups driver using contact 
closure. But this is hard to setup as you need the right cable
and the settings for the driver.

It depends on the fact that it is left in xcp mode. And to get it out of
that you need to send 0xFA or 0XFF to it. But it need to be sent in
the right way Like this 0xAB 0x01 0xFA 0xXX, (where 0xXX is the 
checksum ) this would bring it back to main menu.

One thing to try is to run it in terminal mode instead of printer mode.
