The cp210*.c programs are incomprehesible to me. Any ideas of what's the problem? There is only the cp210x driver now in the latest kernel, older kernels had the cp2101 driver, but it was renamed to reflect that it supported more than just the one device type. Perhaps you are having problems with older kernels and your device, if you could verify that the latest kernel.org release works properly, it would be great. thanks, greg k-h -- 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
