This seemed to get things working...
#OOPS!
sudo apt-get install fxload
#Get the device bus and id.
lsusb
Bus 002 Device 005: ID 0957:0518 Agilent Technologies, Inc.
#Load firmware
sudo fxload -D /dev/bus/usb/002/005 -t fx2 -I
gpib_firmware-2008-08-10/agilent_82357a/measat_releaseX1.8.hex
#Wait for 3 seconds...
lsusb
Bus 002 Device 006: ID 0957:0518 Agilent Technologies, Inc. #<<<
Notice the id change.
sudo fxload -D /dev/bus/usb/002/006 -t fx2 -I
gpib_firmware-2008-08-10/agilent_82357a/measat_releaseX1.8.hex
sudo gpib_config
#Works!!!
