Not me, as I don't have an USB printer, so can't talk for two usb 
printers even!
However, I'm not supprised, as I don't see how printer driver can pass 
USB transport 
which printer device (/dev/printer/usb/*) it should open...
I think Dano updated USB transport addon offer a better support... 

I guess instead if these hardcoded transport=5Faddress sub-menus in the 
Add Printer setup dialog, we may have some mechanism letting each 
transport addon display and handle his own configure view...

But, being R5-compatible is great already here.

Did you post this crash report to our build system guru, Ingo=3F

It don't, sorry:

$ pwd
/boot/home/Desktop/openbeos/current/src/add-ons/print/transports 
$ jam Serial\ Port
[...]
MkDir1 ../../../../objects/x86.R1/add-ons/print/transports/serial=5Fport
C++ ../../../../objects/x86.R1/add-ons/print/transports/serial=5Fport/
print=5Ftransport.o
/boot/home/Desktop/openbeos/current/src/add-ons/print/transports/
serial=5Fport/print=5Ftransport.cpp:38: TransportAddOn.h: No such file or 
directory
[...]

Same for "USB Port" target

I search this TransportAddOn.h in our CVS and in CVS history, without 
any success.
Guess someone forgot to commit his local headers/private/print/
TransportAddOn.h :-)

BTW, "transport" add-on may not be only a print concept, may I suggest 
we rename it
into PrintTransportAddOn.[cpp|h] instead=3F. 
I volunteer to do it, as soon as I get my hand on your TransportAddOn.h 
(or, if you want, I can write one from scratch...).
