Hi all!

I have an Acer Aspire 5720. And built in a WebCam Crystal Eye.

uname -a
FreeBSD nonamehost1 9.0-BETA2 FreeBSD 9.0-BETA2 #0 r225700: Tue Sep 27
12:30:24 EEST 2011     user@nonamehost1:/usr/obj/usr/src/sys/mk9  amd64

When a booting OS visible line: ugen4.2: <Unknown> at usbus4 (disconnected)
...
ichsmb0: <Intel 82801H (ICH8) SMBus controller> port 0x6000-0x601f mem 0x9b305000-0x9b3050ff irq 19 at device 31.3 on pci0
smbus0: <System Management Bus> on ichsmb0
ugen4.2: <Unknown> at usbus4 (disconnected)
nvidia0: <GeForce 8400M GS> on vgapci0
vgapci0: child nvidia0 requested pci_enable_io
vgapci0: child nvidia0 requested pci_enable_io
...

The device /dev/cuse is present, and /dev/video0 is not present,
hence no video in Skype and other applications which use webcam ...
What do I do that would appear the device /dev/video0?

Thanks!
