[OpenWrt-Devel] ralink target, ehci not working, all the devices get detected at ohci controller

[hackru]

Hello,

I'm using fresh openwrt trunk, device is NEXX WT3020H, any device i'm trying to connect gets usb 1.1 speeds, what's wrong?
This thing confuses me most:
Fri May 15 14:48:18 2015 kern.info kernel: [  300.520000] usb 1-1: new high-speed USB device number 2 using ehci-platform
Fri May 15 14:48:18 2015 kern.info kernel: [  300.940000] usb 2-1: new full-speed USB device number 2 using ohci-platform

Looks like some race condition between usb-controllers, maybe i'm wrong. I rebooted router 5 times, always the same result.


Some diagnostics info:
