15:13 <ayaka> naobsd, does the usb work in your firefly rk3288 board with the mainline kernel?

15:13 <ayaka> I have reset the hub manually and confirmed with multimeter

15:13 <ayaka> but it still doesn't work, I doubt whether the driver works well

15:28 <ayaka> anyway I don't wait the usb to be ready, just send the patch first

15:53 <mmind00> ayaka: usb ports in some constellations have issues with usb devices plugged in at runtime ... dwc2 has a bunch of different issues, this being one of them ... there were patches from dianders on the lists addressing some shortcomings, but I don't think they went in yet

16:09 <dianders> ayaka, mmind00: feel free to take up the torch. I think Rob Herring didn't like my solution. https://patchwork.kernel.org/patch/7529101/ and https://patchwork.kernel.org/patch/7529081/

16:09 <dianders> (of course, I didn't like my solution either, but couldn't find one that was better)

16:48 <ayaka> dianders, mmind00 thanks, in this case, I can no more doubt about I do something wrong in dts

16:49 <ayaka> just donate time to fix the usb problem in usb driver
