one thing i have not understood, why it requires to power down when

a USB cable?

why would the phy be powered up for no use ?

After booting, just attach/detach the usb cable, then i have not seen
any issue with power numbers in off mode, RETENTION and active states.

that's because if you boot without cable the phy is left alive,
consuming power for nothing.
