I have a IIsi and I spent some long hours trying to fix the egret driver
about a year ago. In the end it did my head in. BSD and 2.2 kernels
apparently work, though ISTR 2.2 is unreliable. With the benefit of all of
that source code and a lot of experimentation involving systematically
reading and writing registers and sniffing ADB traffic I still coudn't
figure it out. One day, if I get my hands on a logic analyzer, I might
revisit the egret chip, and overcome my aversion to that particular
undocumented bundle of joy.
