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.
Looks this is the same case even for the Rockchip SoC side as well.
Does the stick work if you plug a hub between the board and stick ?
I have observed the same behavior as before It detects very rarely.
Also, RPi zero (?) might have raw host port on it, without hub .
Worth to try, will check it.
Thanks, Jagan
