Research direction
No files or tests are named. Start by reproducing the connection in Chrome 75 on macOS with a micro:bit running firmware 0249 or 0254, then inspect the browser console and WebUSB/serial connection path. Done means clicking Serial opens the REPL and flashing completes without the reported bad-response error.
Written by the indexing model from the issue text.
Description
Clicking on Serial should open the REPL, this doesn't appear to be the case, though the micro:bit does say it's connected.
Recording of trying to connect
If I try to flash the device I get
"Error: Bad response for 17 -> 131 Please restart your micro:bit and try again"
Here is the console output
Have tested this with a micro:bit running 0249 and 0254 on Chrome 75 Mac
