--Apple-Mail=_DE5E0035-3F56-499B-9D34-1D841CC0B373 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=us-ascii Hi, We have a custom Cypress FX2 based data acquisition card connected to a = FreeBSD 9.2 system.=20 Today the device disconnected Oct 9 03:24:11 juskym kernel: ugsio0: at uhub3, port 1, addr 3 = (disconnected) and then some time later we noticed the data acquisition process was = stuck in 'USB config SX lock' (and un-killable). I ran usbconfig and it = also got stuck in the same wchan. I tried rebooting it and got stuck with this on the screen.. usbus0: Controller shutdown complete usbus1: Controller shutdown=20 I have previously run the same hardware on 9.0 (where there was a panic = in devfs triggered if the DAQ card disconncted sometimes) and 9.1 (where = I have not seen any problems). Does anyone have an idea about how I could go about gathering more = information if it happens again?
