Maybe to many protocols enabled?? I thought the manual advise is only the ones needed..
And maybe to many other devices connected to your RPI?

Enabled protocols is no reason for this problem.
In most cases it is a bad power delivered by the RPI to the USB.

Try another USB cable, use a powered USB hub or use the RFXtrxLAN.
The RFXtrxLAN (LAN or Wifi version) has his own power supply and can be located on the best location for 433 receive and transmit.
