M0S_BL616_example\sipeed\solutions\usbd_cdc_acm_with_uart enumeration issue / missing string descriptors
On my "Sipeed M0S Dock" I have built & flashed the example M0S_BL616_example\sipeed\solutions\usbd_cdc_acm_with_uart There is an issue during enumeration which is not working correctly to retrieve iManufacturer / iProduct & iSerialNumber string descriptors.
Same issue for the 3 string descriptors:
iManufacturer : 0x01 (String Descriptor 1)
*!*ERROR String descriptor not found
iProduct : 0x02 (String Descriptor 2)
*!*ERROR String descriptor not found
iSerialNumber : 0x03 (String Descriptor 3)
*!*ERROR String descriptor not found
The issue is this sample does not work correctly most of the time even when the enumeration does not return an error from the OS... See similar issue https://github.com/sipeed/M0S_BL616_example/issues/3
