Part Number: TUSB4041I

My customer is using  TUSB4041i part in a tablet. project . We would like to know is it possible to control the speed of individual ports?

We want to put 2 ports into FS(full-speed) mode to provide good bandwidth to other ports.

 

Please let me know if its possible and how .

    It isn't compliant to limit the capability on a downstream per port basis because you have a single HUB instance and the descriptors would inform of the capabilities of the USB Hub as a whole (not for each downstream port individually) and all downstream port must be able to support the reported maximum speed as per the USB specification.

    Thanks
