I have Epson ES-400 and have a similar issue.
Clean Windows 11 install on a new Asus Z690 motherboard.
Trying different USB ports didn't help.
When the computer is turned on, and I want to scan something, it says scanner is not found.
I have to go to Windows Settings, delete the scanner, power cycle the scanner.
Windows rediscovers the scanner, and it works.
The problem happens again after computer is shut down.
No help from Epson support.
