HAL: NUCLEO_F411RE - Corrected USB clock frequency Modified the main PLL settings so that the USB clock will run at a proper 48MHz instead of 44.44MHz. Consequently, the core clock will now run at 96MHz instead of 100MHz.

It's ok for me... When I have added this platform, it has been requested to run at maximum frequency (100 MHz) and so the clock for the USB was not correct. Hope people who don't use the USB will not complain to run at lower speed... not a lot but lower... Is there a plan to add in mbed API a function that will allow to change the system clock ? |

In my opinion, any target supported by the USB libraries should be correctly clocked for USB operation. The average developer will have no idea how to manually re-clock the chip in order to get the USB libraries to work. On the other hand, developers that want to boost performance should be able to figure out the clocking system on their own. Maybe even overclock it. |
