Hello, I'm Gerardo from Argentina.
I have an HP Pavilion dv6871us notebook.
Let me know how you did your webcam function and if the same model as mine.

The lsusb throws me this:

gera@hpMurray:~$ lsusb
Bus 007 Device 002: ID 064e:a110 Suyin Corp. <---- This is
Bus 007 Device 001: ID 0000:0000

Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000

Bus 002 Device 001: ID 0000:0000

Try the uvcvideo driver but no walks.

Disculpa porque no se escribir bien en ingles.

Hi guys,
I have the same webcam and works fine (cheese or skype), but my problem is different:
the cam disappear from system and lsusb list until bus 007 device 001 instead the cam, when works, is listed in bus 007 device 003.
Someone can help?
For yzhel, perhaps i solved your question installing the backports kernel 2.6.21-higher num. Try this.
