How many USB ports can handle for iMAX6Q custom hardware ?

Dear All,

iMAX6 supports USB 2.0. How many USB 2.0 ports can handle iMAX6Q ? If I connect hub with USB interface are there any limitations for this ?

Regards.

Peter.

Hi Joan,

Thank you for your response.

I need to know how many devices can be used with "One HS host with integrated High Speed PHY" ? If I'm using USB hub. Can I connect 14 devices to usb hub via this host port of iMAX6. How it affect to the data speed and how can we understand its limitations.

Regards,

Peter.
