[sane-devel] Nikon Coolscan V ED: Error during device I/O

[Sebastian Niehaus]

Hi,

I try to use a Nikon Coolscan 5 ED using Debian 9.3 AKA Stretch.


Scanner ought to be supported with the coolscan3 backend.

"scanimage -L" needs very long to list the scanner.
"scanimage -T" reports "Error during device I/O"



Scanner "disappears" after one "scanimage -L" or any other request to do
anything else meaning it is not displayed by doing "scanimage -L"
another time.


Full session as root (to make sore it's not a matter of permissions)


***@radioactive:~# sane-find-scanner -q
found USB scanner (vendor=0x04b0 [Nikon], product=0x4001 [LS-50 ED]) at
libusb:001:027
***@radioactive:~# sane-find-scanner -L
unknown option: -L, try -h for help
***@radioactive:~# scanimage -L
device `coolscan3:usb:libusb:001:027' is a Nikon LS-50 ED film scanner
***@radioactive:~# scanimage -T
scanimage: no SANE devices found

[power cycling the scanner]

***@radioactive:~# scanimage -T
scanimage: open of device coolscan3:usb:libusb:001:028 failed: Error
during device I/O
***@radioactive:~#



Any ideas what could be wrong? Any information you might need in addition?


Thank you very much!

Hi,

You did not tell us what version of sane-backends you are running.
Assuming that it is 1.0.27, there is an environment variable that may
help. Try running

Sane is 1.0.14 (which seems to be identical for all debian releases form
oldoldstable to unstable. However the backend seems to be version 1.1.0
(see debug log below...)

SANE_USB_WORKAROUND=1 scanmage -L
repeatedly, and see if the scanner is listed every time.

The scanner is listed only for the first try and not the second one.

After reading the man page I tried the debug environment variable:



***@radioactive:~ $ SANE_DEBUG_COOLSCAN3=128 scanimage -L

[coolscan3] sane_coolscan3_exit

This was the first try, so I did a second one immediatly afterwards:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
[coolscan3] sane_coolscan3_exit



I have no idea what this could mean. Any hints for me? Anything I can do
to find out why I fail to use the scanner?

Sane is 1.0.14 (which seems to be identical for all debian releases form

(see debug log below...)

"libsane-common" which includes the coolscan3 driver is version 1.0.25

Hmm. I am running Debian. sid, buster and stretch have 1.0.25:

https://packages.debian.org/sid/libsane

jessie has 1.0.24 and wheezy 1.0.22.
