Hi Sirs,
Sorry to bother you.
Currently testing USB HUB has encountered some problems,
We want to connect the TUSB2046BVFRG4 HUB on the PMB via USB via Xhci on the PC, and then use the xhci tool to make the hub output the package to the downstream (upstream is PC), but it has not been successful.
We would like to know how to test the USB 2.0 signal (currently, the downstream has 4 DEVICEs).
Step1
Step 2
We have tried to remove the Rpu 1.5k but it still can’t send out the test pattern..
