Hey,
could it be that EHCI is not working correctly? On my desktop I get irq
3 interrupt livelocks when loading EHCI (actually it is on/off
livelocking). On my laptop it seems to load okay, but then transferring
data to my new mp3 player is slow, basically around 1MB/sec. In dmesg,
cam writes something about "Down reving Protocol Version from 2 to 0?",
but I don't know what that means. Does anybody have a working EHCI setup?
Hm, last time I tried, it was pretty slow. Could you try booting with
tunable hw.usb.hack_defer_exploration set to 0 (see [1]). Does this make
any difference?
Regards,
Michael
