We have had exactly the same problem here (and reported it several
times). The mouse is working up to version 1.1.87, but some serial
driver changes in 1.1.88 broke the C&T chip autodetection. The quick and
dirty fix back then was to bypass autodection (i.e. bypass calling
probe_qp) and force installation.
But things became recently even worse, and since 1.3.26 even that fails
to work. Therefore, I'm running 1.3.25...
