Hi, I'm writing an UIO driver for a plain PC/104 board (ISA bus). After insmod I don't see an entry of uio0 in /dev and also no entries in /sys/class. There are no error messages at module load. The same happens after loading the module uio.ko and uio_pdrv.ko ... no entries at all, no error messages. In the attachment is the kernel part of the driver. What could be the problem? --Armin
