Hi,
On a 12.0-BETA2 system, am seeing lots of this in /var/log/messages:
uhub_reattach_port: giving up port reset - device vanished

There's only two things usb on this machine, a usb3 pci card (which has
nothing plugged into it) and a usb2 wireless key plugged into the usb
system built into the motherboard. It's detected as run0. The device
works fine, doesn't drop packets.
How can I debug this? Should I upgrade to 12-PRERELEASE (or whatever the
latest is) first?
Hi,
There hasn't been any USB changes in this area. Likely you have a broken
or unsupported USB device, which doesn't enumerate properly. I see this
on my computer with a USB bluetooth device, which because it doesn't
receive valid firmware at first boot, becomes in-accessible. Maybe you
can disable some such USB devices in the BIOS.
