Takes ages to find the com port and program

[White-Rabbit-Scientific]

I dunno if it should take this long to find the com port and program, but it does seem rather weird. This happens on multiple PCs but not every time.

What target? I was investigating this myself for an older Sparkfun SAMD51 board, and it turns out that the Arduino bootloader has extensions to do fast "chip erase" and upload, but this wasn't being used because the Sparkfun bootloader was identifying itself as "SparkFun"" rather than "Arduino."

Unfortunately, 14 seconds to erase the flash, one "row" at a time, is not a particularly unexpected amount of time.
