You really are going to have to break out that USB monitor to verify
that this is the data coming across the wire.  Note, there are "cheap"
USB monitors that can be quite handy and that work on Linux:

Or most high-end scopes have a USB mode that you can use to catch stuff
like this (but they are usually harder to use/trigger and only store a
very limited buffer).

good luck!
