Part Number: TUSB2077A

Hi Team,

Customer is using TUSB2077A HUB solution and would like test eye diagram performance, they run USBXHSETT (ver.1.3.6.7) under WIN10 but not able generate test pattern.

the Hub function is ok, customer would like to check if TUSB2077APTR need enable some register to generate test pattern.

I saw another e2e post :https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1031982/faq-tusb8041-tusb8041-how-do-i-force-a-usb-hub-to-send-usb-2-0-high-speed-test-packets-for-eye-diagram-testing

but doesn't see TUSB2077A in the list. would you help us confirm?

Thanks & Regards

Hi Eddie,

The TUSB2077A is a FS hub and does not support HS test packets for eye diagram testing.
