Problem with zs211

Hi !

I am trying to install a little no-name webcam.

Plugin it in the USB port shows :

Jun 16 16:04:14 localhost klogd: usb 3-3: new full speed USB device using 
ohci_hcd and address 7
Jun 16 16:04:14 localhost klogd: usb 3-3: device descriptor read/64, error -62
Jun 16 16:04:14 localhost klogd: usb 3-3: device descriptor read/64, error -62
Jun 16 16:04:15 localhost klogd: usb 3-3: new full speed USB device using 
ohci_hcd and address 8
Jun 16 16:04:15 localhost klogd: usb 3-3: device descriptor read/64, error -62
Jun 16 16:04:15 localhost klogd: usb 3-3: device descriptor read/64, error -62
Jun 16 16:04:15 localhost klogd: usb 3-3: new full speed USB device using 
ohci_hcd and address 9
Jun 16 16:04:16 localhost klogd: usb 3-3: device not accepting address 9, 
error -62
Jun 16 16:04:16 localhost klogd: usb 3-3: new full speed USB device using 
ohci_hcd and address 10
Jun 16 16:04:16 localhost klogd: usb 3-3: device not accepting address 10, 
error -62
Jun 16 16:04:16 localhost klogd: hub 3-0:1.0: unable to enumerate USB device 
on port 3

Once only, I got a good message, inserting gspca zc3xx, showing device 
0ac8:307b
and creating a /dev/video0.

Even in this case, I could not open it with a webam program like cheese 
(/dev/video0 was grey).

I tired it on Mandriva 2010 and Ubuntu 10.04

the windows driver is named zs211.

Is there a way to get it working ?

Many thanks

Gerard
