ar9170#
ar9170usb is a GPL driver for the Atheros 802.11n USB chipset (AR9170).
This driver is deprecated and it was deleted on Linux 3.0, replaced by carl9170.
See also otus, the driver which ar9170 is based on, and carl9170 which drives same hardware.
caveats#
Before you can use the hardware, you have to get the the right firmware.
device driver#
ar9170 will be part of the 2.6.31 kernel release but new updates (such as AVM Fritz support, and support for the one stage open source firmware) will be available until 2.6.32. You can however get the latest ar9170 driver, as targeted in the wireless-testing development tree by using git to get wireless-testing directly or by using the compat-wireless tarball which will get you only the wireless drivers.
