Hi,
Has anyone tried to use dwc2 and echi port together with USB disk? look like this is not working with this combination on any Rockchip SoC's
Here are the issues that I've reproduced in RK3328 where the disk connected in EHCI port is detecting but DWC2 is not. Any clue?
I generally avoid using DWC2 as host. RPi 1/2/3 does use it as host, but I think there is a hub between.
The B models of the 1-3 have a hub.
Also, RPi zero (?) might have raw host port on it, without hub .
Correct, the Zeros, Model As, Compute Modules (inc the CM4) in some configurations and the RPi4 via the USB-C (albeit I suspect rarely used as such) all have dwc2 directly connected.
