\< [19:34:34] Exception while trying to update firmware: \<IspError(‘Timeout’,)\>  
So I bought a double extruder to put on my TAZ 6. However, I keep running into problems trying to update the firmware. I don’t really know what the issue is, but I keep seeing  
\< [19:22:02] Closing the USB printer connection.  
\< [19:28:56] Closing the USB printer connection.  
\< [19:32:26] Closing the USB printer connection.

I don’t know if these two things are related, but I can’t download any firmware, any time I try I just get “Firmware update failed due to an unknown error”  
I am running the latest version of Cura Lulzbot and windows 10, any help is appreciated.
