Epson USB scanner permissions in 9.2

I fear we may have done this in the three weeks I've been away, but, extensive googling hasn't got me where I'm going yet: Epson Perfection 2450 Photo scanner, problem free with 2.4 kernel series, problems with 9.1, partly resolved with kind help of many, partic Kastus and Sid. Now different prob, maybe easier? Kooka works absolutely fine as root, so I am assuming not much is broken and thus not posting scads of logs. But will not work as user. Over what should I shake a rubber chicken to allow users to scan, or is it the full horror again searching through 25,000 nameless files? Cheers Fergus
