Yes, you should be able to reprogram the FBV to send MIDI CC's.
The problem sounds like the FBV will not be recognized.
Please remove all other USB devices (except a mouse/keyboard, and the FBV) while troubleshooting this problem. Completely remove ANY USB hubs, even if not in use, and test the FBV Express Mk II on all of your computer's USB ports.
Try a different USB cable just in case.
If the problem persists, you should test on a different computer to isolate the problem.
Yes, today I've plugged the device in a Windows XP desktop and it worked all ok, from updating the firmware to reprogramming for sending normal MIDI signals. After I returned to my mac, these signals were happily bound by Guitar Rig, so finally I can use the pedalboard.
Monkey and FBV Control still do not recognise the device even after updating the firmware, recalibration and reprogramming. The problem persists.
By the way, I plug it directly in the notebook (it is 2009' Macbook Pro 13"), without hubs and via different cables; though macbook has an internal hub and lots of internal USB devices like a card reader that I can not disable. It can't be the issue of low power (as these USB ports are capable of recharge an iPad), and as we have seen, the device itself works normally. Of course, I might have missed something, like a special setting or update for OS X or Line6 software, so please tell me if there is one.
I had the same problem! But actually I've managed to work it out. I've programmed and updated the device on a PC (Windows 8) and used with Amplitube on the Mac (Snow Leopard).
2 weeks ago I've bought the new Mac Mini!
Turns out the FBV Express doesn't work anymore. It's dead.
Anyone from Line 6 working on this problem?
I read the same problem on a post of 2009...
