Reproducing what was done for the S95 on the sx130 would go a long way to completely solving Alarik's issue.
Hi waterwingz, hope it's not a silly question ? has your splendid work http://chdk.setepontos.com/index.php?topic=7127.120 made any difference to the quoted S95 / sx130 statement ?
The two discussion threads you reference are talking about two different issues. One issue discusses the ability of a CHDK equipped camera to measure USB pulse width. The other is about the ability to sync accurately between cameras. So what I did for one problem does not affect the other.
