Internal speed signal is not updated in USBDevice. #125
Description
7d7960e introduced externally visible speed signal in USBDevice.
self.speed = Signal(2)
and it's updated from the reset sequencer:
self.speed .eq(reset_sequencer.current_speed),
however, there is also an internal speed signal:
speed = Signal(2, reset=USBSpeed.FULL)
This signal is passed into logic blocks, but is not updated at all.
It stays in its reset value.
IIUC, it should also be assigned to reset_sequencer.current_speed.
I wonder though, do we need two different signals in this case?
Probably better to just use the self.speed everywhere.
