Hello,

I have a script to work my scanner. Haven't used the scanner in about two months, and a perm's issue appeared tonight as I tried to use it.

What's odd is, this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.

Error in console:
libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied.
libusb requires write access to USB device nodes.

my sript runs:
scanimage \
--device $MODEL \
--resolution=$RESOLUTION \
-x 5104 -y 6840 \

my groups:
uid=1000(fogie) gid=100(users) groups=100(users),7(lp),11(floppy),12(mail),15(man),17(audio),18(video),19(cdrom),20(games),21(sloca te),83(plugdev),84(power),86(netdev),93(scanner)

Even a simple:
scanimage -Lv

in console gives this on a separate --current pc as well.

any ideas?

thank you.

This seems to be a small bug in libusb1, according to http://libusb.6.n5.nabble.com/libusb...ux-td7545.html

As per this, the error messages are totally correct (most devices in /dev/bus/usb are root:root owned, hence a normal user has no write access), but not meant for the default debug level.

Just wanted to update this thread as being solved as the patch from ppr:kut seems to have been incorporated into Slackware --current, and so far so good. Thanks for sending this off to Mr. V and getting this fixed
