Hi,
I just checked out the 3.7.10-Kernel driver for the wireless Adapter
EW 7811Un 802.11n, ID 7392:7811 and it doesn't work: The driver gets
loaded but some IRQ-errors show up. Using the original driver doesn't
work either 1) driver needs patching for new kernel-API 2) Patched
Driver gets loaded but USB directly suspends and the device seems to
shut down permanently (ifconfig wlan0 up leads to error). I can't
paste any traces now but perhaps these problems can be confirmed after
all.
thx, I'll try it out in the next days.

To be able to work on the error messages from ehci-hcd, it is likely that we
will need all the messages associated with the initialization of the hub. That
is the reason that I asked that you post the entire dmesg output, starting at
time 0.
What encryption are you using?

This kind of error doesn't seem to show up on the USB 2.0 interface. I
just configured the AP for WPA+TKIP but no change. Now the Adapter
won't connect anymore even I reload the module..pretty random error.
I'll try some other ideas in the next days...

I'm using a i686 Architecture on AMD E2-1800 APU with Radeon(tm) HD
Graphics AuthenticAMD GNU/Linux with linux 3.7.10. CONFIG_USB_DEBUG
was allready set. I've used an USB 3.0 port previously and now
rechecked everything with a USB2.0 port. The result is nearly the
same: first connection succeeds (ping response), doing a manual
reconnect to the AP leads to the same error. I've done several
ifconfig down/ups at the end with no change.

I found some problems today. With the attached patched, my device connects to
WEP, WPA and WPA2 networks.

Without the error traces, there is little I can do.

Please do not drop the Cc to the Linux wireless mailing list unless you are

That error is something in the USB hub driver. What is your architecture?
To get a little more detail, please rebuild your kernel with CONFIG_USB_DEBUG
set and post the full log on some paste site. I will likely need to have the
help of the USB expert on this matter, but we need more details first.

OK, the USB3.0 error is a different matter. You should report that on the USB
mailing list.
You need WPA2-AES/CCMP encryption for it to work. I'm looking into that problem now.
Larry
okay now it gets a little awkward: un/reloading the driver seems to
fix the authentication-problem (ip gets assigned), but no ping
succeeds..
