Selon Aurelien Jarno : > You're right that it can cause some problems, on my system I need to > load the ds1621 module before the pcf8591 otherwise my ds1621 chip > is recognized as a pcf8591. In case you didn't know that, you can add a line like this in your /etc/modules.conf file: options pcf8591 ignore=0,0x42 where 0 is the bus number and 0x42 the i2c address of your DS1621 chip. Then you can load the driver modules in any order. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
