Hi,

Firstly, regarding the overcurrent condition that the VIA PCI card reports with the USB 2 devices, it occurred to me that I might have a power supply problem, so I reconfigured that computer to have only the VIA USB 2 controller card, a video card and one hard disk, and the problem still occurred as before. The power supply claims to be 300 watts.
Secondly, the motherboard has a regular ATX power plug, a four prong "pentium 4 / ahtlon" power plug, and a power plug like ones you see on disk drives. Unplugging the last one still gave the same results. (This was a real shot in the dark anyhow.)
So, it seems less likely that it is a physical power problem in the computer, although I wouldn't say that possibility is completely ruled out yet.
The USB overcurrent thing is no real measurement, but AFAICS the OS device driver normally just accumulates the power values as reported by USB devices in some info structure.
I just fixed up lspci on the sparc64 system I mentioned and there is indeed a Ali controller plugged in:

I'll test accessing the AV220 from that box ASAP - but this most probably means tomorrow morning, since I have to recompile the kernel first and have another priority task on my desk ...
Yours,
