I suspect I am doing something wrong in the code with register/unregister_chrdev(), but I have been over that code a million times. It looks fine. Now: insmod the device, OK rmmod the device, OK Check /proc/devices , device # is present insmod the device again, fails with ERROR: could not insert module ./foobar.ko: Device or resource busy On Fri, Dec 27, 2013 at 6:59 PM, <Valdis.Kletnieks@vt.edu> wrote:

I have checked that and the problem persists.
I see insmod and rmmod - but no lsmod output. Not ls, lsmod. Different command.
