The last time I saw this, was when I learned that the libusb callbacks
needed to be defined w/ a different calling convention. If you got UHD
from this installer then I don't know the problem:

If I read your message right, then it seems that the interaction between
PPPOE and UHD may be the culprit. But it wasnt consistent between find
and probe? but I would expect them to behave identically.

It may be the act of opening up a socket on that interface for broadcast.

Windows is that nosey neighbor who always manages to get into your house
at those awkward moments; even though you know you locked the door.
