X18SE goes into EMEGENCY MODE after unplugging USB cable from computer

[gflash01]

I updated from Ethos 1.5.7 to Ethos 1.5.8 today. After ejecting the drives in Ethos, I unplugged the USB cable, and the transmitter went into EMEGENCY MODE and was beeping. Power cycling the transmitter cleared the error. Now whenever I remove the USB cable after backing up my model files, the transmitter goes into EMERGHENCY MODE. I have tried this on two different computers and the behavior is the same. It does not appear to have impacted the performance of the radio, I did a range check prior to flying and flew two flights successfully.

The same thing happened to me with my x18!
