my canon mp280 was working great, and it still prints with CUPS, but the scanner now locks up with the following error messages:

May 19 12:53:17 (none) user.warn kernel: usb 2-2: usbfs: interface 1 claimed by usblp while 'scangearmp' sets config #1
May 19 12:53:17 (none) user.warn kernel: usb 2-2: usbfs: interface 1 claimed by usblp while 'scangearmp' sets config #1
May 19 12:54:20 (none) user.debug kernel: usb 2-2: usbfs: usb_submit_urb returned -121

any ideas??

I set up my MP490 in Lupu with scangearmp from here and checked /var/log/messages. I got the same warnings as you, but the scanner worked fine.

People used to get the locking-up problem if they installed scangearmp without a libusb-1.0 package. It is included in my version above.

rcrsn51 the patron saint of printer/scanners strikes again!

yes installing those packages on a fresh system and it all worked again.

so i rebooted back to my full system and uninstalled those two packages.

this time i made sure they were uninstalled and then immediately rebooted.

presto change-o everything is happy again.

i'm guessing what happened is that the battery went flat after i did the initial install and test, therefore not saving things properly.

wierd evil stuff then happened.

thanks again for fixing my brain so that i was able to fix things myself 8^)

Glad to help.

The libusb-1.0 business is a bit of a mystery. The only USB devices I have seen that require it are Canon scanners. Even the models that will work with SANE (the MP280 apparently doesn't) need libusb-1.0.

There was some discussion about making it a standard part of all Puppies, but nothing happened. I believe that 01micko's spup has it. But he owns an MP490 Wink

IT"S HAPPENED AGAIN!

scangearmp is looking for libusb-0.1 again, specifically, libusb-0.1.so.4, and that symlink is no longer there.

seems every time i reboot my pc i must reinstall the scanner driver!!

Do you have a more conventional machine besides puppeee 504 on an asus EEE PC900 on which to test this?

The scangearmp pet contains libusb-1.0. But it also over-writes a new version of libusb-0.1 for compatibility reasons. It sounds like this latter library is not getting into your savefile.

not sure what you mean by a "more conventional machine"
but it works perfectly on a emachines/win7.

i don't know enough about the layered filesystem inner workings to put forward a theory on why a shared object would not be saved.

maybe something to do with ldd?
