Actualmente estoy trabajando en Debian Stretch (inestable) Kernel 4.9.0-3-amd64 (última versión).
Tengo problemas al usar un ni usb gpib. Primero, mi instalación (que funcionó en mi kernel anterior) es la que se recomienda aquí:https://www.cl.cam.ac.uk/~osc22/tutorials/gpib_usb_linux.html
Estos son dmesglos momentos al conectar el dispositivo:
[73264.867644] usb 3-1.3: USB disconnect, device number 8
[73271.234223] usb 3-1.3: new high-speed USB device number 9 using ehci-pci
[73271.344584] usb 3-1.3: New USB device found, idVendor=3923, idProduct=709b

[73271.344840] ni_usb_gpib: probe succeeded for path: usb-0000:00:1a.0-1.3
Luego modprobe ni_usb_gpibfunciona sin devolver ningún problema.
Pero la ejecución gpib_configdevuelve:
failed to bring board online
failed to configure board
main: Resource temporarily unavailable
Aquí están los relacionados dmesg:
[73665.645045] ni_usb_gpib: attach

[73665.655167] gpib: interface attach failed
Luego, intenté cargar el firmware manualmente, como lsusbapareció:
Bus 003 Device 009: ID 3923:709b National Instruments Corp. GPIB-USB-HS
Lo intenté:
fxload -D /dev/bus/usb/003/009 -I gpib_firmware-2008-08-10/ni_gpib_usb_b/niusbb_firmware.hex -s gpib_firmware-2008-08-10/ni_gpib_usb_b/niusbb_loader.hex
El firmware se ha encontrado aquí:http://linux-gpib.sourceforge.net/firmware/
Aquí está la respuesta:
