FreeBSD 7.2 USB stack info needed

[Sagara Wijetunga]

Hi FreeBSD community 

After an USB thumb drive id pluged in, the devd prints following line: 

+umass0 vendor=0x0781 product=0x5406 devclass=0x00 devsubclass=0x00 
release=0x0200 sernum="087663165D8139E6" intclass=0x08 intsubclass=0x06 at 
port=0 interface=0 vendor=0x0781 product=0x5406 devclass=0x00 
devsubclass=0x00 release=0x0200 sernum="087663165D8139E6" intclass=0x08 
intsubclass=0x06 on uhub4 


1. Could I know which exact program print above line on /dev/devctl ? 

2. I want to print another line with "daN" as the device-name, where N is 0 
to 9, with minimum vendor and product ids once the allocated device-name is 
known for USB Mass Storage devices. Your additional ideas/feedback/help is 
most welcomed. 

Kind regards
Sagara
