The ASUS WL-520gU runs openWrt and has a USB port which the manufacturer claims is 2 but several users state that it only supports USB 1.1 (Jeff: http://www.mightyohm.com/blog/2008/10/b … -platform/ ). That was from April of this year. There have been many developments since then. Can anyone confirm that USB 2 is available under openWrt for this device now?

Can't comment on WL-520GU device. However, I have customized and compiled my own OpenWRT firmware with ONLY EHCI USB2.0 driver for my WGT634U and it has been up running off an external USB2.0 partition just fine with the EHCI USB2.0 driver.
Thanks for the response. I have USB2 working on NSLU2s, so my question wasn't about openWrt's ability, but of the WL-520GU to deliver on its specs.

I have ONLY flashed my WGT634U with a self-built firmware (ONLY has EHCI driver) from the latest (bleeding edge) OpenWRT SVN trunk. As with theOpenWRT 8.09.x firmware, I believe it comes with OHCI/UHCI drivers along with EHCI driver. If both EHCI and OHCI/UHCI drivers are loaded, perhaps there is a chance the device will be served with the OHCI/UHCI drivers that support upto 11Mbps. I guess if you installed OpenWRT 8.09.x firmware without OHCI/UHCI on your WL-520GU router, perhaps its USB will be a full v2. I sure would like to know this. Can you give that a try and let us know here?
I haven't ordered the router yet, because I will be away for U.S. Thanksgiving and won't be able to test before December. I'll try what you recommend when I get back. I also have a use for this which doesn't require USB 2, so no loss if I am unable to get that feature to work on the first one.
Pretty sure Openwrt supports USB 2 for the 520gu now because I managed to get up to 2MB/s from USB to LAN on my 520gu. With USB 1 you can still get 1.5MB/s, so there's not a big difference between USB 1 and USB 2 speeds for this router anyway because of its weak CPU.
Thanks, playdude. Struggles with USB 2 and other reporting of your 2 MB/s are found here: https://forum.openwrt.org/viewtopic.php … 06&p=2
I use an asus wl-520 gu.
both module usb-ohci and ehci-hcd works fine for me.
some details below. as you can see ehci complains (illegal capability!), but i don't know about it.
Nevertheless it seems to be USB-2.0 for me.

From the Linux kernel HELP menu, here is its excerpt:
The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0
"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
If your USB host controller supports USB 2.0, you will likely want to
configure this Host Controller Driver.
EHCI controllers are packaged with "companion" host controllers (OHCI
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
will connect to EHCI if the device is high speed, otherwise they
connect to a companion controller. If you configure EHCI, you should
probably configure the OHCI (for NEC and some other vendors) USB Host
Controller Driver or UHCI (for Via motherboards) Host Controller
Driver too.
You may want to read <file:Documentation/usb/ehci.txt>.It says that the EHCI controllers is packaged with the companion OHCI/UHCI host controllers. My WGT634U runs ONLY with EHCI drivers and it works just fine with a USB2 HUB, USB2 memory sticks, etc. However, if I plug a Nokia DKU5 USB/serial console cable to my WGT634U USB port, it is not recognized even though I have the pl2303 + cypress_m8 kernels built-in into the Linux kernel. I reckon the OHCI/UHCI drivers on EHCI driver don't work. Anyone?
WL520gu doesn't recognize my usb devices.
OK, I'm forced to ask the forum. I've flashed the WL-520gu a dozen times, and I can't get it to recognize any usb devices. It's probably simple, but I've run out of ideas. I'm trying to install a webcam, but have also tried usb flash and sound.
Under Ubuntu I did
svn checkout svn://svn.openwrt.org/openwrt/trunk ~/kamikaze
to a new directory, and then
make package/symlinks
which put me into menuconfig, where I made my selections, exited, and did
./scripts/feeds install mjpg-streamer
I reran menuconfig to select mjpg-streamer, and compiled. Over and over with different selections. In particular, I enabled kmod-usb-core, kmod-usb-video, kmod-usb2, kmod-video-core, kmod-video-uvc, and mjpg-streamer. The Logitec Quickcam for Notebooks, a UVC webcam recognized in other openWrt configurations, is not recognized, nor are other usb devices.
The good news is that the WL-520gu is very easy to flash. Press the reset button and powerup, and within two seconds it is trying to find a tftp server. I used the ASUS Firmware Restoration utility, and it flashes and reboots within about a minute. I put on a cable to an FTDI serial-to-usb cable and I can watch the process, and then access the openWrt prompt with <Enter>.
I flashed openwrt-brcm47xx-squashfs.trx -- is this the right firmware choice?
"uname -a" gives "Linux OpenWrt 2.6.30.9 #3 Thu Dec 3 17:17:24 EST 2009 mips GNU/Linux" and the openWrt splash text gives: "KAMIKAZE (bleeding edge, r18623)"
My config file and dmesg output are in the following post.
What else do I need?

There is only one usb core and the ohci driver initializes it. If compiling for this config, selecting usb2 should also select ohci. However, it doesn't seem to. I'll try to see why.
In the meantime, you will need to select both usb2 and ohci.

So simple. Thank you very much, sbrown. Webcam was identified, usb storage was identified, usb sound device was identified. With this compile, 884K remains for storage on this 4 meg device.
Now to see why the webcam doesn't work. I put the device id in /etc/modules.d/90-video-uvc. The directory, /webcam_www doesn't seem to have been set up for mjpg_streamer, and that program exits with "init VideoIn failed". But progress--thanks again.
Webcam now working. I reflashed a version of trunk without mjpg-streamer, and installed it with opkg to see if that created the directory "/webcam_www", but it did not. I checked my NSLU2, on which the webcam was working, and saw that the files in that directory were not compiled, but were html, java, and the like, so I used scp to copy the directory from the NSLU2 to my laptop and then to the WL-520gu.
After a reboot, the webcam works--a Logitec Quickcam Deluxe for Notebooks. I tried another UVC webcam, the Rosewill RCM-3201V ($25US from Newegg), and that worked as well.
An ebay "UVC" camera failed with the following:
i: Format............: MJPEG
Unable to set format: Invalid argument
Init v4L2 failed !! exit fatal
i: init_VideoIn failed
I won't spend more than a small amount of time trying to figure out a way to make it work--too bad, it was only $13.

The ebay uvc camera mentioned in the last post (http://cgi.ebay.com/USB-5M-WEBCAM-Camer … 2ea944c1a0) streams, jerkily, with the following command: mjpg_streamer -i "input_uvc.so -d /dev/video0 -y -r 640x480" -o "output_http.so -p 8080 -w /webcam_www"&
The "-y" option is what made it work; the camera doesn't perform MJPEG2 encoding. A pretty low-grade camera for streaming, but better than the Quickcam Deluxe for Notebooks for snapshots.
The discussion might have continued from here.
