However you explained before,
the 4.5W is “at least” power of USB3 i.e the any USB3 port must supply a minimum of 4.5W, thus a port with 7.5W is still within spec, deliberately making laptops cut power when current is at 0.9000000000001A is doing more harm than good, a USB port shouldn’t be a “policing” devices IMO. Just my 2 cents.
Regardless, Framework should mark the power ratings alongside the data speed on the picture of ports, a 10Gbps 4.5W is still different than a 10Gpbs 7.5W port
I lsusb -t
on my FL13 and I got this
$ lsusb -t

Where’s USB4 40Gbps, I only got 10Gbps and 480Mbps, or simply because lsusb -t
is inaccurate?
