Re: [OpenWrt-Devel] [PATCH] ramips: mt7620 ArcherC20i USB support
USB port of TP-Link Archer C20i does not work with trunk and CC.
This patch adds two nodes (ehci and ohci) to the device tree enabling USB.

Re: [OpenWrt-Devel] [PATCH] ramips mt7620: ArcherC20i USB support and more
Hi,
The patch (actually the entire file) was contributed on the OpenWrt
forum:
https://forum.openwrt.org/viewtopic.php?pid=281794#p281794
My contribution is that I have tested it and that I am trying to submit
it here.
I can confirm that:
1) My ArcherC20i works fine with the patch applied
2) USB works (which it does not do in CC without the patch)
If the changes not related to USB (ehci/ohci) are questionable, I would
be happy to resubmit a patch for just USB. I am sorry about the spaces
and tabs. The clean patch below looks much nicer.
Gunnar T.

Hi,
Why did you replace all tabs with spaces? This makes the patch hard to
review. Please fix and resend.

It has been discussed here:

I have confirmed it works for me too.
Thank you for your work.
