After 1 day compiling and patching kernels,searching the net etc. i finally SOLVE the problem with the islim 310:
Go to: http://kyleabaker.com/2010/07/12/mic...x-gspca-patch/
Read how to install this patch and install it(This patch is not only for the LifeCam VX-1000). Reboot u PC after installing!
in this patch in module gspca_pac7302 is added VID(903a) PID(2625) and is used by gspca_main to work with that hw. U can chk this by typing:
#modinfo gspca_pac7302 , after installing patch
and u can see module working in lsmod
GOOD LUCK !
i hope u will find this helpfull
