mounting USB - Stick, Grafic adapter, Scanner TWAIN

Postby CK-62 on Wed Nov 07, 2007 5:22 am

Hello there,

Can anybody help me out on following:

1.) How to mnt automatically a USB Data Stick in Mint 3.0 KDE (Cassandra) CE and lounch the file manager (An external USB HD works fine while USB Data Sticks don't)?
2.) Is it possible to run Nvidia proprietary driver for Grafics Adapter called "Point of view GF 7300GT", which I think basically comes down to a Nividia chipset/Grafix Adapter GF 7300 GT. How and where would I need to adapt settings if possible (Installing manually & automatically by Envy did not work out sofar, because recognition of adapter failes - actually it is run by VESA settings)?
3.) What file do I have to copy the Firmware USB file to, within Mint 3.0 KDE for running the scanner, with Sane? (I understand this should be /usr/local/share/sane..., Sane is installed but does not show up here)
Scanner is USB Twain Artec e+48 - sane supported)
Lounching Sane shows an "invalid argument" for the scanner connected.

Thanks in advance to anybody helping me!!!

1 should be done automatically, but not opening the filemanager, showing a selection dialog instead (works on my system)

3 Scanner: well, if it is supported, then run kooka to scan. to find the scanner (no copying needed afaik) proceed as shown in the man sane-find-scanner (pasted from the website):


sane-find-scanner - find SCSI and USB scanners and their device files


sane-find-scanner [-h|-?] [-v] [-q] [-p] [-f] [-F filename] [devname]


sane-find-scanner is a command-line tool to find SCSI and USB scanners
and determine their Unix device files. Its primary aim is to make sure
that scanners can be detected by SANE backends.

For SCSI scanners, it checks the default generic SCSI device files
(e.g., /dev/sg0) and /dev/scanner. The test is done by sending a SCSI
inquiry command and looking for a device type of "scanner" or "proces-
sor" (some old HP scanners seem to send "processor"). So sane-find-
scanner will find any SCSI scanner connected to those default device
files even if it isn't supported by any SANE backend.

For USB scanners, first the USB kernel scanner device files (e.g.
/dev/usb/scanner0), /dev/usb/scanner, and /dev/usbscanner) are tested.
The files are opened and the vendor and device ids are determined, if
the operating system supports this feature. Currently USB scanners are
only found this way if they are supported by the Linux scanner module
or the FreeBSD or OpenBSD uscanner driver. After that test, sane-find-
scanner tries to scan for USB devices found by the USB library libusb
(if available). There is no special USB class for scanners, so the
heuristics used to distinguish scanners from other USB devices is not
perfect. sane-find-scanner also tries to find out the type of USB chip
used in the scanner. If detected, it will be printed after the vendor
and product ids. sane-find-scanner will even find USB scanners, that
are not supported by any SANE backend.

sane-find-scanner won't find most parallel port scanners, or scanners
connected to proprietary ports. Some parallel port scanners may be
detected by sane-find-scanner -p. At the time of writing this will
only detect Mustek parallel port scanners.


-h, -? Prints a short usage message.

-v Verbose output. If used once, sane-find-scanner shows every
device name and the test result. If used twice, SCSI inquiry
information and the USB device descriptors are also printed.

-q Be quiet. Print only the devices, no comments.

-p Probe parallel port scanners.

-f Force opening all explicitly given devices as SCSI and USB
devices. That's useful if sane-find-scanner is wrong in deter-
mining the device type.

-F filename
filename is a file that contains USB descriptors in the format
of /proc/bus/usb/devices as used by Linux. sane-find-scanner
tries to identify the chipset(s) of all USB scanners found in
such a file. This option is useful for developers when the out-
put of "cat /proc/bus/usb/devices" is available but the scanner
itself isn't.

devname Test device file "devname". No other devices are checked if
devname is given.


sane-find-scanner -v
Check all SCSI and USB devices for available scanners and print a line
for every device file.

sane-find-scanner /dev/scanner
Look for a (SCSI) scanner only at /dev/scanner and print the result.

sane-find-scanner -p
Probe for parallel port scanners.
