If it isn't then > maybe we should blacklist it unconditionally? Without the libusb based proprietary stack, the device is unusable under linux. If i correctly understand, libusb need a driver to be present in the first place, (even a useless generic-usb) to be able to grab the device. If we unconditionally blacklist the device and the ebeam driver isn't loaded (not compiled for example), no way for libusb (and the stack) to handle the device. As stated before, i'm not comfortable with the risk of breaking other hypothetical support, even proprietary. -- Yann Cantin A4FEB47F -- -- 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/
