Hi,
I installed the latest iscan packages from download.ebz.epson.net and can not
get my (RX500) scanner to work. The backend works as much as providing the
device name through sane_get_devices(), but sane_open() exits the application.
Adding SANE_DEBUG_EPKOWA=16 does nothing.
I also have a

I got a bug-report about failure to open an Epson network scanner with

The scanning works OK with Skanlite if started with the device-name as a
parameter, but if the device parameter is omitted and the device selection
dialog is used, the opening of the device fails.
