FS#3323 - Buffalo WZR-600DHP needs kmod-usb-ohci for USB to work

In both openwrt-15.05.1-ar71xx-generic-wzr-600dhp-squashfs-tftp.bin and openwrt-19.07.3-ar71xx-generic-wzr-600dhp-squashfs-sysupgrade.bin USB did not work. Power was available at the USB port, but plugging in various USB devices did absolutely nothing. I had to install kmod-usb-ohci to make USB start working.

I feel this is a bug because in 19.07.3 kmod-usb-ehci is already installed. So, one might think that required USB modules are there and something is wrong.

I tried both USB 1.1 and 2.0 high speed devices before. The ohci module is required even to use USB 2.0 high speed devices.

Just for other people looking into this:
This is an ar71xx device not supported in ath79 (yet). It's set up in image/ there, and I have no idea how packages are selected there.

Probably this will not be fixed for ar71xx anymore.

As far as I can tell the WZR-600DHP target doesn't exist anymore. All ar71xx targets have been dropped in;a=commit;h=4e4ee4649553ab536225060a27fc320bf54e458c and a new ath79 target hasn't been created for this specific model. Yet WZR-HP-AG300H, which shares the same board apparently, is in ath79. It does have kmod-usb-ohci in;a=blob;f=target/linux/ath79/image/;hb=17e64b9447959858c5c85f7f6c98264775585711#l341 (ie. it is not affected by the same problem).

The WZR-HP-AG300H ath79 firmware did seem to work fine on the WZR-600DHP, but I'm not using it because I'm not clear on what are the differences between the two devices and what might break.

The device would be suitable for porting to ath79 as it seems, just somebody has to do it.

It appears the device is just identical to WZR-HP-AG300H. I've created a PR to include WZR-600DHP as separate device in ath79 master:

Would you build and test?
