Hi, using the '-c' option clears the buffer contents after printing
them once. Therefore subsequent 'dmesg -c' will output nothing unless
some kernel activity has take place.

*1  dont use '-c' , "dmesg > boot.txt" ,    will work fine.
*2 su is required for dmesg -c but not for dmesg (witout any options)
*3 covered by 1&2 above.
Also you can have a look at /var/log/kern.log for all the kernel messages.
Run a $ tail -f /var/log/kern.log  then watch the messages fly past as
you plug your devices .

HTH,
Jasbir.
