I have a Lexmark Z52 usb printer. To get it going I put the following into /etc/udev/udev.rules:
# USB Lexmark Z52 printer to be called lp_Z52
BUS="usb", SYSFS_product="Lexmark Z52", NAME="lp_Z52", SYMLINK="usblp0"
But hotplug/udev ignored it and started:
crw-rw---- 1 root lp 180, 0 2004-01-08 17:46 /dev/lp0
with no symlink.
I got the "product" label from:
asterix:udev> cd /sys
asterix:sys> find . -type f | xargs grep Z52 2>/dev/null
./devices/pci0000:00/0000:00:02.0/usb1/1-1/product:Lexmark Z52
To be very sure of what was in the string:
asterix:sys> s=$(find . -type f | xargs grep Z52 2>/dev/null); s=${s}"XX"; echo $s
./devices/pci0000:00/0000:00:02.0/usb1/1-1/product:Lexmark Z52XX
asterix:sys> echo ${s##*:}
Lexmark Z52XX
asterix:sys> echo ${s##*:} | od -t x1
0000000 4c 65 78 6d 61 72 6b 20 5a 35 32 58 58 0a
0000016
asterix:sys>
Should my rule with SYSFS_product have worked?
Is my syntax wrong?
Where am I misunderstanding?
Newbies like me could use heaps more rule examples.
TIA,
Bob Barry

You may try the extras/udevinfo/udevinfo program.
This is quite new, so I want to know if this can help.
Change into the directory and type "make me" to build it.
Then execute "./udevinfo /sys/class/video4linux/video0" and it will print
all possible attributes in the key format for a rule.
looking at class device '/sys/class/video4linux/video0':
SYSFS_dev="81:0"
SYSFS_name="OV511 USB Camera"
SYSFS_custom_id="21"
SYSFS_model="Creative Labs WebCam 3"
SYSFS_bridge="OV511+"
SYSFS_sensor="OV7620"
SYSFS_brightness="97"
SYSFS_saturation="192"
SYSFS_contrast="86"
SYSFS_hue="128"
SYSFS_exposure="0"
...
Good luck,
Kay

I tried the udevinfo of udev-014. It has no man; no help for
--help, -h, or no args; it does not seem to accept wild cards;
it does not take arguments from standard input
("find ... | xargs udevinfo" does not work); and "udevinfo -a"
does not list "all", as would be useful.
I finally got an
"all dev" listing with:
for d in $(find /sys -type f -name dev | sed 's~/dev$~~')
do
./udevinfo $d
done
The list is attached. My printer is there, but all that's offered are
cryptic numbers:
SYSFS_detach_state="0"
SYSFS_bInterfaceNumber="00"
SYSFS_bAlternateSetting=" 0"
SYSFS_bNumEndpoints="02"
SYSFS_bInterfaceClass="07"
SYSFS_bInterfaceSubClass="01"
SYSFS_bInterfaceProtocol="02"
SYSFS_iInterface="00"
There's no sign of the "product" I'd found, or of "name" or "model".
Am I missing something, or misconfigured?
TIA,
Bob Barry

Sorry, udevinfo accepts only one sysfs path for one specific device,
not a list what xargs expects.
There are no options besides this one argument.
"./udevinfo /sys/class/usb/lp0" should work, but it seems that it
doesn't get the information you looking for.
I don't have any usb printer, what does:
"tree /sys/class/usb"
"tree /sys/devices/pci0000:00/0000:00:02.0/usb1"
print on your machine?
thanks,
Kay

No, you are correct. The "problem" is that usb drivers are bound to usb
interfaces (which is the directory you see above). What you really want
to compare using udev to is the usb device directory, which is one above
this directory. I know about this problem and am working on fixing it
in udev.
Sorry about this...

I don't have tree. I replaced fileutils and others with coreutils; perhaps
there was an oversight. Will have to hunt for it.
But I battled on with /proc, /sys, and find. I found where the files are,
but udevinfo (and presumably udev itself) rejects that path. It's all in
the attached file - please have a look.
Thanks,
Bob

Greg and Kay -
Thank you both for answering all my questions of this thread in the
most comprehensive possible way: udev-015 is installed and
working beautifully. My usb printer rule now works, and udevinfo
is really useful now.
Kay -
A few small observations about udevinfo:
- when I run udevinfo -h, the "-V" line displayed is:
-V print udev version
it should be
-V print udevinfo version
'cuz that's what it gives when I run udevinfo -V
- I'd suggest a default "all" option for query, to show
the entire database entry of the specified node,
as is shown by udevinfo -d
- the man page does not mention the -a option
- for newbies, a few example command lines
would be useful
Best Regards,
Bob
