Re: Using gpib library with Beiming Technologies S82357

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!!!
