I bought Wi-Fi USB dongle Netgear WNDA3200. It's based on Atheros AR7010+AR9280 chipset and it is supported by ath9k_htc driver.

I'm running Ubuntu 12.04 with kernel 3.2.0-30-generic (x86_64). This device is recognized correctly and lsusb shows:

Bus 008 Device 005: ID 0846:9018 NetGear, Inc. WNDA3200 802.11abgn Wireless Adapter [Atheros AR7010+AR9280]

But dmesg shows error:

usb 8-1: ath9k_htc: Transferred FW: htc_7010.fw, size: 72992
usb 8-1: ath9k_htc: Unable to allocate URBs
ath9k_htc: probe of 8-1:1.0 failed with error -22
usbcore: registered new interface driver ath9k_htc

There are 3 firmware files in my /lib/firmware

ar7010_1_1.fw
ar7010.fw
htc_7010.fw

How to ger rid of error: Unable to allocate URBs?

Thank You.

In Ubuntu 12.10 "Unable to allocate URBs" error disappeared and Netgear WNDA3200 is working fine.
