Why would a userspace driver not work out for this. We already can saturate the USB bus with a userspace program, and since it requires a userspace interaction to do something with the data, I don't really see what a kernel driver could do to help thing out. That being said, perhaps it would fit with the other USB data acquisition drivers that we already have. Feel free to take this up with me off-list if you want to. Hm, wait, in looking at the specs for the device, it uses a usb-to-serial chip that we already support quite well (with the pl2303.ko driver.) So all you need to do is write some userspace software that interacts with the device properly. No new kernel driver is needed at all, as Linux already supports this hardware :) thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
