im using the starter set of sos-solutions (raspberry rfxcom and so on) for about a year now with no problems.
but when i came back from work i descovered that my system did not work anymore.
the rfxcom's red light is flashing continously.....but when connected to the rfxmngr on my laptop it works fine.
last night i saw in the log files some error with the usb.
in the hardware section in domoticz the rfxcom is still there but with no Seriële poort i can choose.the active box is not checked anymore but that does not change a thing.
all the wireless devices are gone in domoticz

so what i have tried is:
-connect rfxcom to laptop-->works fine
-replaced the software on the sd card of the raspberry with a backup i made-->same result
-tried a different power supply on the raspberry-->same result
-i googled how to check the raspberry's usb ports (with putty)and came up with this command : lsusb -t
this is the result:
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc_otg/1p, 480M
|__ Port 1: Dev 2, If 0, Class=hub, Driver=hub/5p, 480M
|__ Port 1: Dev 3, If 0, Class=vend., Driver=smsc95xx, 480M
according to the site this means there is nothing connected to the raspberry.....
can i solve this problem and how?????
and how can it die suddenly??
