The machine locked solid before it printed the probe line for the Atmel hub. Trying to drop to the debugger did nothing, no response to Caps-Lock keys, and so on. > It's having problems with the connected hub device.=20 > Is this 100% reproduceable or just from time to time? I only tried booting with ACPI disabled once. Without the line hint.acpi.0.disabled=3D"1" in /boot/device.hints, the system boots fine, but plugging in USB devices does nothing -- my original message, at http://lists.freebsd.org/pipermail/freebsd-current/2004-April/025164.ht= ml has more details. With that line (following a suggestion to disable ACPI) the system hangs at boot. > Does the hub really have it's own power supply as it claims? Yes. The hub is integrated in to the monitor. Note, however, that I'm seeing problems with devices plugged in to the motherboard's USB ports, *and* the hub's USB ports. > Please retry with a USB_DEBUG kernel - in case of a broken device the > probing may take serveral minutes - maybe we should give some output > without USB_DEBUG too in this case. Will do.
