Hi Mauricio,
The problem seems tied to the alternate setting. It must be the #3
while the lastest versions of gspca compute a "best" one. May you apply
the following patch to gspca-2.13.6?

(Theodore, this webcam may work in mass storage mode with ID 04fc:0171.
In webcam mode with ID 04fc:1528, it offers 3 interfaces: interface 0
contains only an interrupt endpoint, interface 1 is the webcam with
only isochronous endpoints and interface 2 contains bulk in, bulk out
and interrupt in endpoints - I don't know how to use the interfaces 0
and 2, but sure the interface 2 could be used to access the camera
images)
