The register interface of the USB controller works, but no interrupts are happening. With some wrong IRQ programming I got interrupt storms, ended up calling the USB interrupt handler all the time and *that* resulted in a working USB stack :-) In short: once we find out what's happening to the (internal) interrupt steering of the VIA southbridge, we should have USB as well. I still assume we can get it to work... The embedded I/O devices (COM1, LPT, etc) are not working yet. I get all 0xff when reading from the well-known I/O ports. I don't know if that's ever going to work, because I presume it needs a lot of configuration on the VIA. -- Marcel Moolenaar xcllnt@mac.com
