Subject: dxp and saturn vortex on usb2

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.
