Dear Larry and Florian,

I'm sending you this email, because you are marked as maintainers for 
the module r8712u. I had to patch it, in order to let it recognize my 
USB WLAN adapter from Sitecom (WLA-1000). Basically, I had to add the 
following line inside drivers/staging/rtl8712/usb_intf.c (line 89):

     {USB_DEVICE(0x0DF6, 0x005B)},

Would it be possible to have the following included in the next kernel 
version, so that we don't have to patch and recompile the kernel everytime?
I created the patch on kernel 3.1.7. The driver is working fine using 
the latest firmware from Realtek (2.6.6.0.20110401).

The output I have from lsusb is the following:

The following is the output I get from dmesg, after having plugged the 
WLAN adapter in:

That's it. I apologize in case you already received a patch for this.
