power matters

So... just because something needs 5V does not mean you should charge it from USB.

Yes, I'm talking about zaurus. I noticed that it crashed rather quickly when connected to USB power. (For example in tar/rm test, dies in less than five minutes). So I took multimeter, and there was 4.15..4.5V on USB :-(. With _good_ 5V source, connected by thick cable, zaurus is stable for hours.

I guess it is software problem in the charging code, but...
