USB / digital camera problems in 9.2
 

I have tried two digital cameras which both worked fine under 9.1 and they both don't work under 9.2.
I can get thumbnails with a powershot G5, but can't download the images. (Not with the konqueror interface and also not with digikam)
Dmesg says things like
usb 2-1: new full speed USB device using address 5

A Nikon D70 didn't work either.
I think this is a kernel problem, does anyone know a solution?
