6. Module loading
=================
To use the driver, it is necessary to load the "et61x251" 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".

"usbcore" and, depending on the USB host controller you have, "ehci-hcd",
"uhci-hcd" or "ohci-hcd".
Loading can be done as shown below:
