Hi all,

I'm loading the firmware_v4 as John suggested, however when I connect
the
usb dongle it crashes:

Linux video capture interface: v2.00
em28xx v4l2 driver version 0.0.1 loaded
usbcore: registered new interface driver em28xx

em28xx: device is attached to a USB 2.0 bus
em28xx: you're using the experimental/unstable tree from mcentral.de
em28xx: there's also a stable tree available but which is limited to
em28xx: linux <=2.6.19.2
em28xx: it's fine to use this driver but keep in mind that it will move

It seems that it's not even loading the firmware, does any body know any
idea in how to solve this issue?
