It seems as though after getting Rasplex running off a USB stick, I can no longer connect to the device via SSH.
I'm trying to add some skins but its impossible as it keeps giving me Connection Refused. This doesn't happen on my other RPI that's booting directly off my SD Card
The solution I found was to add "ssh" to the end of the boot line of the cmdline.txt file
I use 2.1 on a usb stick. I forget which posting its in, but it was given by one of the lead developers. I just verified that I couuld ssh in now. Since I rarely need to.
