I am receiving this error "Netbotz daemon.err root: nbPPP: Missing nbSerialPortDev for nbSerialPort_0" in the appliance log of my Netbotz 500 Wallbotz.
It was working perfectly and all of a sudden i was not receiving any SMS' and looked at the appliance log and saw this error.
I have rebooted, power cycled the unit a few times to no avail. I also managed to restore from a previous working backup and yet no luck. I have disconnected the modem and reconnected but nothing.
Modem status is "unknown" - i feel this could be the end for my Multi-Tech MultiModemGPRS modem. any ideas before i start looking for other modems ?
See below error;
Netbotz daemon.err root: nbPPP: Missing nbSerialPortDev for nbSerialPort_0
FYI - i feel i have posted this issue before but cannot find the initial query but the issue resolved itself back then... (apologies for my ignorance)
Any help is greatly appreciated.

I had this problem on three Netbotz appliances, in all cases it turned out to be the 5m USB extender cable. Replacing the cables fixed the issue.

Thank you Dominic.
I will try my utmost to get another cable and hopefully this solves the issue, what puzzles me is I dont have an extender cable, its a normal USB cable (connects to a HUB) and what looks like a printer port that connects to the modem
Will sowp it out and hope for the best.
Your help is appreciated - thank you!
