CC @pawelzadrozniak, will defer to him |
|
As far as I know, all supported controllers on STM32 SoCs are USB 2.0 compliant. |
|
There could be a configuration option to choose between 1.1 and 2.0. |
Only if there is no other way. e.g. if we have a non 2.0 compatible controller |
|
The SAM0 is USB2 so you're good there. I can't think of any reasons to support USB1.1. |

bcdUSB has been previously updated from 1.1 to 2.0 in default device descriptor, but not in DFU class. After USB bus reset performed by dfu-util, alternative descriptor is registered with bcdUSB set to 1.1. This mismatch causes communication failure. DFU descriptor's bcdUSB has been updated to match default one. Relates to zephyrproject-rtos#7570 Signed-off-by: Paweł Zadrożniak <pawel.zadrozniak@nordicsemi.no>

There is suggestion/need to increase bcdUSB to 2.00. Are all supported controllers USB Rev. 2.0 compliant?
?🆗 (STM32F1, STM32F3, STM32F4, STM32L4 USB 2.0 Specification compliant )?🆗 (SAM D21, SAM R21 Family module complies with the Universal Serial Bus (USB) 2.1specification)
