The driver is heavily based on existing Cinergy T2 Hi, it looks like your patch is broken again. As it wasn't a separate attachment, long lines got wrapped by the sending mailer. At least I wasn't able to save it without wrapped lines. Attached is a fixed version that applied and compiled fine for me. Regards, Tino
