I have a USB3343 connected to the STM32F407IGH, but it is not operating at USB High Speed.It works with USB Full Speed.Please advise us about the cause.
Hi oleksandr.karbivsky,I suspect that the LPM (Link Power Management) function of USB3343 is affecting it.I suspect that STM32F407 cannot control the LPM (Link Power Management) function.
