RTL8192cu: not work on linux-2.6.35

[Brilliantov Kirill Vladimirovich]

Hello!
I work with board on FreeScale iMX287 CPU and use linux-2.6.35.
For use WiFi USB Trendnet TEW-648UBM I download driver 
(rtl8188C_8192C_usb_linux_v4.0.2_9000.20130911.tar.gz) from Realtek site 
and build it.

Unfortunately wireless-tools can't work with interface wlan0:
~ # iwconfig --version
iwconfig  Wireless-Tools version 29
           Compatible with Wireless Extension v11 to v22.

Kernel    Currently compiled with Wireless Extension v22.
~ # iwconfig wlan0
wlan0     no wireless extensions.
~ # iwlist wlan0 scan
wlan0     Interface doesn't support scanning.

Yes, this chip supported in latest linux, unfortunately now I can't run 
new linux on board.

Can you help run rtl8192cu on linux-2.6.35?
Thank you and excuse me for my bad english.

Sorry, but there is no way that any of us can support a Realtek vendor driver. 
In addition, I have never tested any of the non-mac80211 drivers for the 
RTL8188CU or RTL8192CU devices.

You have the latest vendor driver that I know about.

Do you found any solution for this problem right now. I have totally the
same Problem and didn't find anything.

This Problem happens with a Netgear WNA1000M and only with some of this
WLAN-Sticks (I tested more then 1000).

That driver was not added to the kernel until 2.6.37, thus I would not expect it 
to work with 2.6.35. If you cannot upgrade to a newer kernel, then you should be 
able to get one from Realtek.com, or from 
http://github.com/lwfinger/rtl8192cu.git. Note that the latter driver is 
directly from Realtek, and is provided only as a service. I take no 
responsibility for any bugs or failures to build.
