High speed USB printer device communication issue on WINDOWS 11
I encountered an issue that windows 11 keeps enumerating the high speed usb printer based on LPC546 mcu, until the OS switched to full speed mode and the enumeration successed. I used ellisys USB protocol analyzer to capture the enumeration process, the result shows as the picture below. It's wired that the OS suspended the device after getting device ID, and resumed and started over the enumeration multiple times until the OS enumerated in full speed mode.
I tested the same printer on WINDOWS 10, and it worked perfectly in high speed mode.
So, does anyone have encountered the same problem and solution to it, please tell me.
Much appreciate!!
Jason
