Comment #16 fixes it on my Dell E5420.

The funny thing is, that normally the error message appears randomly, but when I insert my Nokia CS-17 3G-modem, the error always appeared three times in a row:

I don't know how a device in USB port generates error messages related to a video driver, but it is.
