This won’t solve the main problem here, but I’ve just uploaded a new version of the EggBot driver (2.6.4) which reverts to the older pyserial version, so that you should not need to copy the serial version from the 2.5.0 release. Please install this version for further tests.
Also, when you try to establish contact with the EBB, please use the “Check EBB version” manual command, for consistency.
With 2.6.4 installed, try to contact the EggBot with the USB cable unplugged. Does it still freeze, or give you the “not found” message?
