I'm running Win10 in Fusion on a Mac. It detects the 552 but not the 476

Hello Steve,

this is a setup we cannot reproduce.

Could you open the device manager ?

Normally, when plugging a board, you should see the update.

Also, when plugging the STM32L476 you should see the LED1 and LED3 active.

Best regards

Jocelyn

SOLVED! When it first failed I change the USB lead. It didn't work with the second lead either. I should have tried a third lead! Now with a third lead everything is fine. Worth nothing that not all USB leads are the same! Thanks STM for your support :)
