There were no errors, however, there is _still_ no /dev/video.
Unplugging and then plugging in the camera gives me this:

Most likely this version of the driver doesn't recognize your
camera. I would look now into the source code, whether the
vendor and product id of your camera can be found.
In similar situations with wlan usb sticks I could add the
missing ids and the stick simply worked. This works very
often, because the driver is made for a chip inside the device,
but these chips are used then by many vendors with their unique
vendor ids. The driver checks whether a device with his chip is
installed by probing for all vendor and product ids it knows.
If a new vendor decides to use this chip, or a vendor makes a
change of the product id, it is invisible for the driver.

Hi Gerald

Good tip. But this Vendor:Product ID is in the newest version of gspca.
From the changelog:
Release 01.00.17
Added basic support vor Pixart PAC7311 based webcams :-), Thomas Kaiser & Joerg
Schummer
make:
0x093a:0x2600, 0x093a:0x2601, 0x093a:0x2603, 0x093a:0x2608, 0x093a:0x260e,
0x093a:0x260f
This was a hard, exhausting and very long journey to get this chip working
The support is not so good: Bad picture quality and not all controls are
working, but we have at least something


Thomas
