Boot: USB MSC boots intermittently
USB MSC Host boot may fail due to a protocol timing violation present in the ROM USB device enumeration process. USB DFU boot is unaffected.
No workaround is available. Some USB MSC devices may tolerate this protocol violation and function as expected. Due to the internal component variability of broad-market MSC devices, a list of tolerant devices cannot be provided.
