Part Number: TUSB1210EVM
currently, it tries to operate [controller + usb 2.0 camera] .
The states of each jumper are as follows.J1 [open]J2 [open]J3 [2-3]J5 [1-2]J6[1-2]J7[open]J8[open]J9[1-2]J11[open]When configured in this way, the USB protocol analyzer recognizes it as LS communication. How do I configure jumper pins for HS communication?And when J9 is set to [2-3], the clock is not output, and I am curious what the functions of J8 and J11 are.Please understand that the context is strange because I used Google Translator.
For HS operation, configuration registers XcvrSelect and/or TermSelect must be changed by the MCU to enable HS communication. Default setting is FS/LS if not changed by the MCU.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Brian Zhou:
When executing J9 [2-3], Vbus is not output. Is Vbus output only when TUSB1210 and MCU communicate?
In reply to kiyong nam:
J9 is CS, which is nothing to do with Vbus, can you check CPEN ? it should be high to turn on Vbus in host mode
CPEN is in the LOW state.It was set to 1.8v on the reset pin. I purchased two TUSB1210EVMs and tested them under the same conditions, but none of them output Vbus.
