Hi Terry, Can you tell if there is some resource
being consumed? Memory, files open, etc? Can you send me a copy of the
initial error messages? Unfortunately I don’t have a USB 2.0 Saturn I
can test with. I did verify recently that on Linux it is
not possible to restart the IOC without power-cycling the USB 2.0 Saturn. This
does not happen on Windows, and it does not happen on Linux with the USB 1.0 or
parallel port versions of the Saturn. Mark From:
[email protected] [mailto:[email protected]] On Behalf Of Terry Cornall Hi. I’m running two saturn-vortex spectrometers
connected via usb2 to Centos 5 linux IOCs which are running the dxp2-8-1
packages with epics 3.14.8.2. I have libusb 0.1.12-5.1 It all works initially, (after a bit of a tussle with
usb permissions) but the usb on both appears to fall over after about 20 hours
of continuous running and the xerxes.c errors start, apparently about not being
able to contact the vortex anymore. (failed to locate detChan 0 and
so-on) To fix it, I power-cycle the vortex and restart Epics.
Just re-plugging the usb doesn’t do it. Has anyone else seen this sort of thing and have any
suggestions about how to cure it? I’m sorry I’m short on detail,
still looking. Thanks.
