Yes, the TL-WR3420 and TL-WR3220 use GPIO 6 to control power to the USB. =
(That info is in the commit message for that change to ar71xx_gpio.c)

Sorry, ignore my changes to TP-WR1043ND{.hints} that's just me playing =
around.  (I've taken the soldering iron to my WR1043ND and added an =
SD-Card socket to the SPI bus, using GPIO 1 as SPI_CS2, that's why the =
pin definitions have changed.  There's no driver for MMC/SD in SPI mode, =
but maybe I can fix that some other time. :-)

> * You also changed the delay to three and commented it out. :-)

Yes, that is intentional:  I'm back to the original iicbb.c code; we =
might want to add the delay hint to it, but it's not strictly necessary.

That is my plan, give me a few days to untangle all the changes and =
package them up nicely.
