hotplug is not a command, it's a kernel sybsystem (well, there can be a 
program called hotplug that serves hotplug events but can also just be a 
simple shell script).

Using dmesg messages is fine if you just want to debug stuff but it's 
really a very bad solution for anything production. (among other things 
it's racy). Learn to use the hotplug sub system. that is what it's for.

If you want, our "Advanced embedded Linux" course has a section on the 
subject and the slides are freely available (OK, you have to get a free 
Scribd registeration because I'm lazy :-) has some slides on how that 
works - http://tuxology.net/courses/advanced-embedded-linux/

Oh, and please DON'T remove the list from CC if I answered you on the 
list. I want other people to enjoy the answers to (this is the whole 
point of mailing lists). This is not a private consulting session :-)

Cheers,
Gilad
