I have a 11th gen Framework Laptop and at some point recently Windows (10) started sending me notifications about a unknown usb device drawing too much power. I tested around a bit with my expansion cards (no other usb devices were plugged in) and this issues comes up when any card is plugged in at any port. I have a usb c, usb a, displayport and hdmi card.
Edit: I also tried connecting a USB hub directly which also resulted in the same notification.
2nd Edit: Now the notification showed up with just the power cable connected
I’d get in contact with support if you haven’t already, I’m sure they’d be happy to help troubleshoot this (just know that responses may be a little slow since they are responding to a lot of questions about the new announcements right now)
