How to use both USB ports simultaneously in K66

Hi,

I am working with MK66FN2M0VLQ18 MCU with our own customized board . We are already using USB0 as Host in our design.

As part of future expansion of our product we need two USB ports, both should be Host. K66 MCU has two USB ports(USBHS and USBFS).

My question is can we use both USB as Host simultaneously? If so what are the changes we need to expect in both hardware and software?

No one else has this question

Thanks in advance.

Regards,

Anand.S

Hello,

Hope you are doing well. My name is Sabina and I'll be happy to assist you with the information. First I'd like to make sure I am understanding correctly, you have successfully been using the USB0 as host and would like to implement the HS USB1 as a host at the same time.

Is this correct?

Physically these both have the capacity to work as USB hosts. I will confirm if it is possible to use simultaneously.

Best Regards,

Sabina
