If you mean a device node, that is a logical file in /dev, you will not find any for the scanner. 1) For the scanner. First of all, make sure your scanner is supported ! I switched from canon to epson because canon scanners were not very welle supported. Then, you have to emerge sane-backends with the usb useflag set. Figure out which backend your scanner use on the sane website (sane-project.org, if memory serves). Then, in the config file of the backend, set the usb id : usb product id device id For example, I added use 0x4b8 0x110 to /etc/sane.d/epson.conf for sane to detect my epson 1650. If your scanner is always plugged, you'll need to emerge coldplug and rc-update add coldplug default. You might have permission problems at that stage. Check the permissions on /proc/bus/usb/001/007. You must have rw rights to be able to use the scanner. 2) For the CD burner. It seems your cd-burner uses the usb-storage driver. It should then appear as /dev/sdX, provided you configured your kernel correctly. It should be useable at that address. You can do an lsscsi to figure out what to tell cdrecord, but any GUI (k3b...) should be able to detect and use your burner. I hope this helps, -- Jonathan -- gentoo-user@gentoo.org mailing list

Hello,
I want to use linux for dvd writing and scanning.
Both my scanner (Canon) and my dvd writer (BenQ) are usb devices.
How can I know which device files these devices use? Or how can I
configure a device file for these devices?
I strongly recommend udev rules to create symlinks. The problem is
that mass storage devices (harddrives, CDs, DVDs, flash drives, etc) are
assigned the next available device name. If you have 2 or more such
devices, their entries in /dev depend on the order they're plugged in.
udev rules allow you to create English symlinks that will always be the
same, and will point to the correct /dev entry, regardless of order of
plugging in. I'll run through what I did. You can follow along with
your DVDRW.

1) You must either login or su as root to do all the following.
2) *WITHOUT* the device plugged in, execute the command fdisk -l.
Here's my output...
[m3000][root][~] fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes

/dev/sda61705 19457 142600941 83 Linux
3) Connect the device, insert media if required, and wait 60 seconds
for the necessary hand-shaking.
4) *WITH* the device plugged in, execute the command fdisk -l.
Here's my output...
[m3000][root][~] fdisk -l
Disk /dev/sda: 160.0 GB, 160041885696 bytes

5) Look for new devices (*NOT* partitions). Disk /dev/sdb is my
new device... *THIS TIME*. If I unplug it, plug in one or more other
USB devices, and plug it in again, it'll be a different device. To
work around that hassle, we need a udev rule that creates a consistent
symlink.
6) Use the command udevinfo -a -p /sys/block/??? x.txt to get udev
info for your device. Note that this variant only works for block
devices. Replace the ??? with the device name in /dev. It should be
something like sda or sdb, etc. Mine was sdb, so...
[m3000][root][~] udevinfo -a -p /sys/block/sdb x.txt
7) This will include a lot of output. It'll have the main USB bus, the
USB ports, and also the device itself. Here's the important part for my
shirtpocket USB drive...
ID==2-2
BUS==usb
DRIVER==usb
SYSFS{configuration}==
SYSFS{serial}==1E0009C22E4B
SYSFS{product}==LaCie Hard Drive USB
SYSFS{manufacturer}==LaCie
SYSFS{maxchild}==0
SYSFS{version}== 2.00
SYSFS{devnum}==2
SYSFS{speed}==480
SYSFS{bMaxPacketSize0}==64
SYSFS{bNumConfigurations}==1
SYSFS{bDeviceProtocol}==00
SYSFS{bDeviceSubClass}==00
SYSFS{bDeviceClass}==00
SYSFS{bcdDevice}==
SYSFS{idProduct}==0341
SYSFS{idVendor}==059f
SYSFS{bMaxPower}== 2mA
SYSFS{bmAttributes}==c0
SYSFS{bConfigurationValue}==1
SYSFS{bNumInterfaces}== 1
Use any combination of the above keys that is unique enough *FOR YOUR
NEEDS* to generate a udev rule. If you've got 3 kids with identical
model mp3 players, and only one will connect at any time, then BUS, and
SYSFS{idProduct}, and SYSFS{idVendor} should be sufficient to identify
the device. If two or more will be connected simultaneously, you'll
need to key in on SYSFS{serial} to differentiate between them. Note;
you *MUST* copy the keys *EXACTLY*, including leading and trailing
spaces. I suggest cut-and-paste.
In addition to identifying the device on the system, you also have to
tell udev what the device will be called, and also what symlink to use
for it. Here is my rule for the above device; yours will obviously be
