Hi, if you can, you should immediately send it back. It is really bad
device.
According to specification found on Phillips support page, this is
640x480 with interpolated 1280x960 resolution. According the usb dump it
can get 640x480 only in MJPEG format. In RAW-YUV it get max
320x240@5fps. Skype on linux use only RAW format, so if you will be
lucky you will get 5 frame per second. For this price (amazon.de 20€)
you can get better webcam.
UVC device should just work (even on linux). If it is not working, it is
most probably bad.
