install ricoh webcam

Hi I’m new to Linux and openSUSE, and I want to get the webcam on my Sony laptop to work. I found this r5u870 driver on YaST and installed it, and now lsusb shows

Ricoh Co., Ltd Visual Communication Camera VGP-VCC6 [R5U870]

but still the system cannot find any webcam nor does the applications. What should I do next after I install the driver?
