Upgrade to 9.3: epson 1260 perfection not recognized

After the upgrade from 9.0 to 9.3, that went without a glitch otherwise, my Epson scanner 1260 perfection (usb) is no longer recognized. It *does* show up in the hardware inventory of suseplugger, but *not* in the list produced by /sbin/lsusb nor in /proc/bus/usb. I tried both the epkowa and the plustek driver, but neither can communicate with the scanner. This seems like a hotplug issue. The scanner works in the OS that shall not be named, so it is not a hardware issue. Any ideas? -- Jos van Kan www.josvankan.tk
