hmm, ok, i have tried it with ubuntu 9.10 live CD and it works! great ;o)
so i have tried run this live CD from computer where device is normally
connected and problem is back... :o(
so IMHO this looks like HW problem?

ok first mail with attached log i have send directly to you, so sorry for
mistake ;o)
so here is different part:
first 89lines are same:
[sanei_debug] Setting debug level of hpljm1005 to 255.
[sanei_debug] Setting debug level of sanei_usb to 255.
[sanei_usb] sanei_usb_init: marking existing devi
i forgot to write that i have disable CONFIG_USB_SUSPEND in my kernel too...
ok, i have tried to comment out calls
sanei_usb_claim_interface and sanei_usb_release_interface with patch below
but it didnt help, device usb reinit still occurs in dmesg (as in my first post)
any other suggestions or ides?
thanks for your patience
patch:
diff -r -u sane-backends-1.0.20-orig/
ok, thanks
here is kernel version:

hi all
i have device HP LaserJet M1005 MFP, scanning is working with "hpljm1005"
backend.
but there is one issue: utility "scanimage" works only every second run
in kernel log i see:
[40719.182679] usb 1-5: default language 0x0409
[40719.183156] usb 1-5: udev 12, busnum 1, minor = 11
[40719.1831
Try getting some more debug output:
SANE_DEBUG_SANEI_USB=255 SANE_DEBUG_HPLJM1005=255 scanimage 2>1.log
then repeat with a different log file, and lets see if anything funny shows up.

Scanimage itself does not send any usb packets, this is the domain of
the backend. The hpljm backend does call sanei_usb_claim_interface and
sanei_usb_release_interface, even though this has already been done by
sanei_usb. But, I'm not sure that would be the cause of the problem,
or why it has not
perhaps related to kernel usb suspend settings to save power? What
kernel version is this? Perhaps you can try to disable power
management for this device (use the 'on' setting):
