Part Number: TUSB2046B
Other Parts Discussed in Thread: TUSB2036


I have interfaced USB-HUB "TUSB2046BIRHBR", which has 4 downstream ports.
I need to use only 2 ports, remaining 2 ports I don't want to use in my project.

But when I check "Dmesg" logs unused downstream ports also show.

so how can I disable unused ports in USB-HUB.

whether unused ports (D+ & D-) signals required any pull-up or pull-down resistors to VCC & GND respectively.?

Please give an exact solution to my problem.
