It will only be possible to compile-test the driver, nothing more. For real testing, other steps would have to be taken before.

There are multiple reasons, more or less technical. This is an older ARM926-based platform. The hardware has some architectural quirks that require patches to other drivers first, like the pl190 VIC driver, the amba-clcd driver, the generic USB OHCI driver etc. The current kernel is based on stable 2.6.39.4 kernel, but following the mainline development more closely is necessary. Russell King and all the others are doing a great job to consolidate the whole ARM architecture, but that means following a lot of changes in all places at a quick pace. I know that it's possible to get the job done if somebody really wanted. > thanks, > greg k-h Best regards Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
