Hey,
I tried my camera logitech quickcam e2500 (046d:089d) with ekiga and its working. As i had read in a thread, i installed libv4l and then used the instruction:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so

However its still not working with gridflow , infact when i select and device #0 to#7 in #camera it causes PD to crash. Now what?

Sisil.
