MSC incorrect enumeration when pc booting #92

Open telix001 opened 4 years ago

telix001 commented 4 years ago

When I connect the Feather M0 Express board (only the bootloader is programmed) to the computer's USB port before turning on the power, and then turn on the computer, the msc enumeration does not work correctly.... Operating system startup takes a very long time. The uf2 disk is not detected correctly..

and correct enumeration when the system is already running and I connect M0 Exprress to the usb port:
