Trial version, get Error 433: A device which does not exist was specified

Hi,

I just installed the trial build for 32 bit Raspberry pi.  I have an ESP32 connected to one of the PI's USB ports.  It has a program that communicates to a terminal window connected to it's USB port.

The install using that curl... command went OK.
When I run the client on my windows 10 it shows the device.  ( A syilabs CP2102x which is the port on the ESP32 )

I can connect to it using vhui42.exe and it looks like it works.
In windows device manager it pops up as COM5.  All looks good so far.

I run putty with a serial interface set to COM5.  Settings the same as when the ESP32 is local to my PC.  When putty tries to connect it responds with  "Error 433: A device which does not exist was specified".

 

Any Ideas?

Use the ESP32 device via virtualhere then on the PC  client open Device Manager View -> By Connection->VirtualHere USB 3 Extensible Host Controller and find the COM port under that then right click on it and select Properties. Does it have a Power Events tab? If so UNcheck allow Windows to turn off this device
