[arch-general] Epson USB scanner / new problem

I have a new problem with a usb scanner - testing repo - fully updated + kde + initscripts (not yet converted to systemd). This was working fine when last tried 3-4 weeks ago The scanner is not being initialized correctly somehow, daemon log shows this upon plugging scanner into USB port: Oct 8 12:05:10 wise kernel: [ 2319.943018] usb 1-1: usbfs: interface 0 claimed by usbfs while 'iscan' sets config #1 Oct 8 12:05:14 wise kernel: [ 2324.094930] usb 1-1: usbfs: interface 0 claimed by usbfs while 'iscan' sets config #1 It is epson v300 - and I'm using the iscan tools from AUR. Any suggestions? thanks.
