Hi,
We selected LPC54606J256ET180E to develop portable printer, which connects to PC by USB1 in HS mode.
Before, our printer works well in windows7 or windows10, but when connects to windows11, USB1 interface will handshake to windows11 for about 10s, then change to FS mode.
Meanwhile, we test the printer with STM32F723, it is quick to connect in FS mode.
We have checked the LPC5460x Reference Manual, but can't find any option to fix this problem.
Hope you can provide us some tips to fix.
Thanks very much.

Hi jimmyli
Did you test USB1 with one of MCUXpresso SDK USB demo code?

Hi Jennie,
Yes, we have verified with the offical demo, and the phenomenon is the same.
Demo: LPCXpresso54628
SDK: SDK_2_10_0_LPCXpresso54628\boards\lpcxpresso54628\usb_examples\usb_device_printer_virtual_plain_text\bm
Thanks.
Thanks.
I need to check it more internally. Please send me this information:
1. your project application name( scenarios of your application)
2. I don't have a win11 to test. please provide me the problem related screenshot.
Thanks for your cooperation.

Could you please confirm if this is correct one?
