There is a typing mistake: "After an USB thumb drive id pluged in" should be 
corrected as "After an USB thumb drive is plugged in". Very sorry for the 
mistake. 

Btw, I have started looking at umass.c and will have a look at later at 
usb.c of /usr/src/sys/dev/usb/. 

Any help is still very much appreciated. 

Best regards
