Issues with measurements: 2207

Hi, I recently purchased a Picoscope 2207.
There seems to be something wrong with the measurements.
When measuring a standard USB bus, the output on the screen looks like a sin wave (goes negative as well).
Voltage is also close to 12volt.
I don't understand this.
I am using the PP821 probes.
