It does show up in dmesg, however. Then, slowly over time, I get a repeating sequence of three error messages. If I unplug the device, it panics in uhci_device_ctrl_start with a null dereference. It looks like xfer->pipe is null. The system fails to sync and doesn't make a crash dump, but I'm guessing the real problem occurs earlier anyway. What can I do? --------------070209070808050001080607 Content-Type: text/plain; name="umass-errors" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="umass-errors" Copyright (c) 1992-2004 The FreeBSD Project.
