The Line 6 Updater application and drivers may be downloaded here: http://line6.com/software/

OK, I am new to this Line6 setup, but where on that page does it say "drivers".

 

The video "Line 6 AMPLIFi 75, 150, & FX100 - How to Update Firmware" is for bluetooth update, which repotedly is flakey and does not work.

Not impressed so far.

While it's true that Line6 recommend updating via computer/USB rather than Bluetooth, the latter can work. I have purchased both a Amplifi FX 100 and an Amplifi 30, and have used Bluetooth to load the latest firmware to each without a hitch.
