Hi Harald,
I think we have some success in examining the code within the Orite
IC301 ipcam, whose drivers are distributed in binary only form, which,
from this appearsto violate GPL.
We have discovered various things, like busybox is being used,
unattributed, along with this lot attached below....
The file referred to as W99683.c is a low level devicedriver fora
WinBond camera chip.
Now what do I do ?
