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.
