I strongly disagree with you. While each and every SD card should conform to the standard, a driver for a host controller should be as forgiving as possible. If the driver cannot cope with cards sold today, the user has a bad experience. I code drivers for people and not for standards. Remember, this is only a timeout. Lengthen the timeout will have no consequences for cards which behave. best regards ? i. A. Wolfgang M?es -- Auerswald GmbH & Co.
