As far as I know, the driver is precisely made for people who build a board according to Simon Vogl's schematics. If you provide details about the failures, we might try to help. > Finally I'm using direct parallel port access and everything works > fine with the i2c-pport driver :-) Great. Couldn't you do the same with more simple parallel-ports adapters, such as i2c-philips-par, i2c-elv or i2c-velleman? These have been ported to Linux 2.6 already, and are supported by my unified driver too, while i2c-pport hasn't been ported and isn't part of the unified driver. Actually I wonder if I will port and/or integrate the i2c-pport logic in Linux 2.6, because in most cases, the additional complexity shouldn't be required. But if you really need it, I'll think of it. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
