Hey guys, I've tried searching for the solution on the web but I can't figure out what the problem is.

As soon as I turn on my Spider IV 75 amp my FBV Express mkII goes out of USB mode (disconnects from the computer and windows can't find it despite beeing plugged in) whitch prevents Line6 monkey to find my amp or FBV. With the amp turned off I can update and work with the FBV Express on the computer but as I said, once the amp is turned on it disconnects from the computer and gets ready to rock instead which prevents me from updating or editing the amp.

What am I doing wrong?
