Hi (Tiss the Glory we steer)

Purchased a Microbit on 18 October 20  
Unable to communicate through a USB cable using Ubuntu 20.04 and the Screen Application.  
Updated the Firmware to 0253  
The Terminal program just hangs no Logs info.

I used the Microbit Purchased on 21 August 20 with the same setup as above and that produces the expected REPL prompt and works Ok.

Any ideas ? I am 90% sure its the board. Can you send me Another one?  
Unfortunately I am not on the Internet at Home so only check email once per week !! I could Phone in with more details if required.
