Re: [Xen-users] Passing a USB printer to a Linux DomU

[Thomas Jensen <tom.jensen@xxxxxxxxxxxxxxxxxxxxxx>]

There is actually a pretty decent explanation of how to do USB  
printing on the OpenVZ site.  I figured that the differences for  
passthrough can't be that different.  That How To really focuses on  
the issue you are referring to about entries in the /dev directory.
It was one of the first places I looked when I encountered my problem.

I have the following entry in the /dev directory:

lrwxrwxrwx 1 root   root           7 Feb 10 23:19 usblp0 -> usb/lp0

ls -l /dev/usb shows:

crw-rw---- 1 root lp 180, 0 Feb 10 23:19 lp0

Further more, my USB printer is on the fourth device as a result of lsusb:

Bus 005 Device 001: ID 0000:0000
Bus 004 Device 002: ID 03f0:6204 Hewlett-Packard DeskJet 5150c
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

A ls -l /dev/bus/usb/004 shows:

crw-rw-r-- 1 root root 189, 384 Feb 10 23:19 001
crw-rw---- 1 lp   lp   189, 385 Feb 11 12:17 002

I did not manually create any of these entries in the /dev directory.   
I presume they are all created as a result of the pci passthrough.   
Furthermore, my printer is displayed in the output of lpinfo -v:
network socket
network beh
direct usb://hp/deskjet%205100?serial=MY3AN4J3337A
direct hp:/usb/deskjet_5100?serial=MY3AN4J3337A
direct hpfax
network http
network ipp
network lpd
direct scsi

Any other suggestions?  It appears that it is very close to working as  
anticipated.
