Following are my observations- a)I find my "dev" i.e. "modem" being created in /sys/class but the directory is empty. Is it that I need to make nodes inside this directory? b)Now should I make the nodes using mknod ? While compiling the driver I *again* encountered the following message. wait_for_sysfs[8956]: either wait_for_sysfs (udev 039) needs an update to handle the device '/class/tty/cum8' properly (class specific file unavailable) or the sysfs-support of your device's driver needs to be fixed, please report to Kay Sievers wrote: >On Wed, 2005-01-05 at 14:36 +0530, shyam wrote: > > >>It would be nice if anybody could tell me how to create a "dev" file in >>my /sys directory. >> >> > >You may look at: > drivers/base/class_simple.c > >how a simple version of class device is doing it, which is needed for >udev to create the /dev node automatically for you.
