Hello,
My USB printer, an HP Photosmart P1115, is desperately seen by FreeBSD
as a ugen device, i can't get it to be seen as an ulpt device. Any help
would be much appreciated, i have been trying various tricks without
success. And my wife will only shift from Linux if she can print on
FreeBSD, which is a good motivation :).
My kernel is stock 4.8-STABLE, it has in particular the following
options for USB:
# USB support
options USB_DEBUG
device uhci # UHCI PCI->USB interface
device ohci # OHCI PCI->USB interface
device usb # USB Bus (required)
device ugen # Generic
device uhid # "Human Interface Devices"
device ukbd # Keyboard
device ulpt # Printer
Here are my USB devices, my printer is seen....
drakkar# usbdevs
addr 1: UHCI root hub, VIA
addr 2: Standard USB Hub, Atmel
addr 3: product 0x08b0, Logitech
addr 4: photosmart 1115, hp # Yes!
... but unfortunately as as ugen:
drakkar# dmesg | grep ugen
ugen0: Logitech product 0x08b0, rev 1.10/0.00, addr 3
ugen1: hp photosmart 1115, rev 1.10/1.00, addr 4 # Sigh
I went further, and installed udesc_dump:
drakkar# udesc_dump /dev/ugen1

...now i am puzzled, because for what i know, the interface
Class/SubClass/Protocol for my printer should be enough to be matched by
ulpt.c:
bInterfaceClass 07
bInterfaceSubClass 01
bInterfaceProtocol 03
My kernel is compiled with USB_DEBUG, and the following sysctl flags are
set on:
hw.usb.debug=1
hw.usb.ulpt.debug=1
...but nothing much showed up in /var/log/messages, as i would have
expected.
Oh, and usbd_enable="YES" is set in my rc.conf.
So i am completely blocked. I found two other users blocked with USB
printers detection in the mailing lists. Have we all missed something?
Or have we all stumbled on the same bug in the USB layer?
Thank you in advance for any help,
Xavier de Labouret
