HWS EX working again

Nutsinee, Dave:

we had two problems in getting h1hwsex running again: It was running a new kernel which is missing the frame grabber driver, and the fiber was plugged into the wrong port on the card.

h1hwsex by default runs a later kernel (3.19.0-78-generic) than h1hwsey (3.19.0-49-generic). The '78' kernel is missing the edt kernel object needed to drive the frame grabber card. For a quick fix for today, I rebooted h1hwsex while standing in front of its console at EX and interrupted the boot to force a boot to the 3.19.0-49-generic kernel (it is under the U14 advanced options on the boot screen, using the non-recovery version of the '49') kernel.

The fiber/transceiver was plugged into the right hand side of the card in h1hwsex. When I moved it to the left, the code detected the camera. I went to EY and verified that the transceiver is also on the left port of the card in h1hwsey
