Doesn't work with the Raspberry Pi Debug Probe

[CyanBlob]

I've got a Raspberry Pi Debug Probe and I cannot seem to read any data from it using mio-serial (or Tokio-serial) on Windows. I haven't been able to test any other OSes at the moment. The example code and my code both work as expected with a generic FTDI-based USB to serial converter. The Pi Debug Probe also works just fine with serial monitoring tools such as Tera Term.

Is this limitation expected? If not, what can I do to help get Pi Debug Probe support added?

Thanks!
