That is a very broad subject. Did you look at the book, Linux Device Drivers, third edition? It has numerous chapters that cover this topic (hotplug, usb, driver core, etc.) I recommend starting with that (the book is free online if you do not want to purchase it.) Also the www.linux-usb.org and linux-hotplug.sf.net web sites are good places to start. good luck, greg k-h -- Kernelnewbies: Help each other learn about the Linux kernel.
