RFXCOM issues

Hello,

I have an rfxcom usb device (for rts shutters), and i can’t find the problem.

I’m running HA as hassos in ESXI.
within ESXI I linked the hardware to the HA vm.

the shutters/switches work well for a few weeks, until they no longer open/close & on/off.

the only thing that works then is rebooting HA or reconnecting rfxcom usb.

I’ve had this problem for years, but I don’t know if it’s a hardware or software issue.

USB cable from rfxcom already replaced
already replaced the host ESXI is running on
HA + integration recreated
unfortunately the issue keeps coming back

Who can help me further?
rfxcom device defective?
rfxcom not programmed correctly?
firmware outdated?
