Lan Turtle keeps connecting/disconnecting usb device

[DonBigly]

I had been losing remote connection lately, and after visiting the device on-site, I can see on the host system that the usb is being plugged/unplugged every 20-30 seconds or so? The actual device isn't rebooting or shutting down, just the usb connection is being flakey. 

Thoughts?

Just to be clear; the title says "Lan Turtle keeps connecting/disconnecting usb device", what USB device is the LAN Turtle connecting/disconnecting? Or, is the LAN Turtle the "usb device" mentioned. It's rather unclear. My interpretation when reading the text in the post is that it is the LAN Turtle that keeps on connecting/disconnecting. So, if it's the LAN Turtle, then I would probably do two things. 1) Try another USB port on the same machine to which the LAN Turtle is attached. 2) Use the LAN Turtle with another host/machine/computer and see if the problem keeps on showing up. Just to rule out if it's the Turtle that is the problem or the target machine that the Turtle is connected to.

Yea the lan turtle is the usb device (as the "usb ethernet" recognized the system keeps going online/offline). It doesn't power down or anything, it doesn't have a reliable connection as far as being recognized by the host. and the actual ethernet connection seems to lag/pause during these disconnect cycles - which causes it to drop from my c2 instance as well.

So i've been still trying to figure this out and finally was able to access the host machine logs, it seems that on OSX there's some sort of "link quality" check that drops below some threshold and attempts to reconnect I guess? It basically drops and re-establishes the connection, then fails it's "link quality" shortly after and repeats.
