Rfxcom stops working

[ubee]

I have a Domoticz configuration (v3.5877) on Rasp 2 with a RFXCom433 attached(firmware version Ext/1006). It has worked fine for a while with a few temp sensors (Viking) and Nexa switches. Occasionally I miss temperature readings from one sensor due to bad coverage, but I can live with that.

However the last few days RFXCom I have run into problems. Rfxcom stops. Or at least no temp data is received and I can't control any Nexa switch either. The log does not give any info. No lines labeled Rfxcom. Sometimes I can get things working again by re-enabling the Rfxcom HW device on the HW tab. Doing so I can see in the log how the Rfxcom module is initiated and temp readings start to come in. However, yesterday RFXcom stopped again, and this time re-enabling the HW module didn't help either. Nothing showed up in the log, but after reboot everything is fine again.

It seems the FTDI USB interface is locked. In most cases this is due to a spike on the power or a bad RPI power supply.
Possible solutions:
Do not run the USB cable along power lines,
Use a good quality power supply,
Connect the RFXtrx to a powered USB hub (with a good quality power supply).
