I'm looking at the udev man page, and it looks as though rules like this might work: # The Prolific Technology 2303 (commonly in tandem with SiRF chips) BUS="usb" ACTION="add" SYSFS{vendor}="067b" SYSFS{product}="2303" \ NAME="gps%e" \ HOTPLUG="/usr/bin/gps-probe" # FTDI 8U232AM BUS="usb" ACTION="add" SYSFS{vendor}="0403" SYSFS{product}="6001" \ NAME="gps%e" \ HOTPLUG="/usr/bin/gps-probe" # Cypress M8/CY7C64013 (DeLorme uses these) BUS="usb" ACTION="add" SYSFS{vendor}="1163" SYSFS{product}="0100" \ NAME="gps%e" \ HOTPLUG="/usr/bin/gps-probe" 1. Am I correct that when triggered, these would create a device called /dev/gpsN for some enumerated N? 2. What is the lifetime of that device? Under what circumstances is it removed? -- Eric S.
