Linux driver WLAN
The WLAN chip of the AGCO WLAN / Bluetooth – Module, AW-GH321, is controlled
by the following linux-drivers:
- libertas
- libertas_spi
When the driver detects the WLAN chip, first the firmware must be uploaded. The
current version of firmware is fw 9.70.3p37. The corresponding files (spi8686.bin and
spi8686_helper.bin) must be situated in the filesystem in /lib/firmware/libertas.
When set up, linux will bring up an eth-device. Now the standard-linux items can be
used for communications.

controlled by the following linux-drivers:
- standard USB driver
- NXP-ISP1760 driver (USB hub)
- Generic Bluetooth USB driver ver 0.4
The device is enumerated by the standard- and ISP1760-USB drivers. All following
accesses to this chip are done with standard-linux-tools for USB (e.g. hcitool) via the
Generic Bluetooth USB driver ver 0.4.
