Unable to open USB port device file: Permission denied

I have an up-to-date system (full "pacman -Syu" yesterday), I am in a "lp" group and the printer (Canon Pixma MP270) started to give "Unable to open USB port device file: Permission denied" error, although in the past it worked and still works in Windows. Doesn't anybody have a similar problem?

Re: Unable to open USB port device file: Permission denied

Is CUPS working?  Are you able to access anything @ localhost:631?

After I upgraded this weekend CUPS would not start properly.  And when I ran "rc.d restart cupsd" it failed to start. 

Not sure if this is the same issue as yours, but see here https://bbs.archlinux.org/viewtopic.php?id=148496 and here https://bbs.archlinux.org/viewtopic.php?id=148692.  Seems that printers are breaking all over the place.

I ended up needing to install avahi and inlclude avahi-deamon to my rc.conf to get it fixed.

Good luck!

Thanks for reply.

CUPS worked, I could use CUPS-PDF and localhost:631 was accessible and working.

Today I managed to print again. I did "pacman -Rcsn cups" and reinstalled it again.

My printer is Canon Pixma MP270 and so far it wasn't the best choice for Arch Linux—scanning works fine but it's like throwing a coin when it comes to printing. I've written a simple PKGBUILD for installing its printing driver as a regular package, but I don't know what to set as a license.

pkgname=mp270-printer
pkgver=3.20
pkgrel=1
pkgdesc="Canon Pixma MP270 printer driver"
arch=('i686')
url="http://software.canon-europe.com/products/0010753.asp"
license=('unknown')
depends=('libpng12' 'gtk2' 'popt')
makedepends=('deb2targz')
source=(http://files.canon-europe.com/files/soft37268/software/MP270_debian_driver_pack.tar)
md5sums=('d26c36e2d1799ddc09e644dc7765f0a3')

build() {
	cd $srcdir
	tar xzf cnijfilter-mp270series-$pkgver-1-i386-deb.tar.gz
	cd cnijfilter-mp270series-$pkgver-1-i386-deb/packages
	deb2targz *
	tar xzf cnijfilter-common_$pkgver-1_i386.tar.gz
	tar xzf cnijfilter-mp270series_$pkgver-1_i386.tar.gz

	ln -s /usr/lib/libtiff.so usr/lib/libtiff.so.4
}

package () {
	cd $srcdir/cnijfilter-mp270series-$pkgver-1-i386-deb/packages
	cp -r usr $pkgdir/
}
