USB3 SSD getting USB 2 speeds
New USB3 SSD plugged into blue USB port of rpi4. SSD 100% powered by the USB port. No other USB devices plugged in. Using stock pi power adapter (came with bundle).
lsusb -t ```
/: Bus 02.Port 1: Dev 1, Class=roothub, Driver=xhci_hcd/4p, 5000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 480M |_ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M |__ Port 2: Dev 3, If 0, Class=Mass Storage, Driver=uas, 480M ```
Wondering if port isn’t providing enough power; could that cause a switch to USB2 bus? Any ideas? Thanks.
EDIT:
Found this article discussing the power consumption of my SSD (Crucial X6). Looks like peak consumption is 3 W, but mostly hangs around 2 W. Rpi 4 ports should be able to handle that easily.... so now I'm even more at a loss.
