6. Module loading
=================
To use the driver, it is necessary to load the "zc0301" module into memory
-after every other module required: "videodev", "usbcore" and, depending on
-the USB host controller you have, "ehci-hcd", "uhci-hcd" or "ohci-hcd".
+after every other module required: "videodev", "v4l2_common", "compat_ioctl32",
+"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
+"uhci-hcd" or "ohci-hcd".
Loading can be done as shown below:
