Every time I set up ModeSDeco I seem to struggle with this. Not complaining about the program , just not great with computers. Could anyone help me by letting me know what the Device number is and how I can find out what it should be? Everything was working fine until the latest Windows 10 update and my re-installing of the Zadig driver. At the moment it is set for Device being 1 in the.bat file but I am getting the 'Device:1 already in use)' and 'Bad File Descriptor' error. Is there anywhere I can look on the PC to see what the Device number should be? At the moment when I look at the device info for the RTL2838 it is Port_#0002.Hub_#0005, not sure if that helps.

Really appreciate any help/advice.

Thanks in anticipation.
