ap problems on foxboard g20 (embedded arm board)

[Waldemar Brodkorb]

Hi,

I would like to use a Foxboard G20 (http://foxg20.acmesystems.it/doku.php)
as an access point.
I have chosen a prism p54 based usb stick from SMC as wireless card.
On an alix2d board (x86 architecture) everything works fine as
expected. But on the Foxboard my client does not associate 
with the access point. Same kernel version, same driver, same
configuration and the same hostapd version. Seems to be an ARM architecture
specific problem, f.e. on a Lemote Yeelong (MIPS64) based netbook,
the stick works although fine.

On x86 I see following:
# hostapd -v
hostapd v0.7.1
User space daemon for IEEE 802.11 AP management,
IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator

But on the foxboard:

Any idea what could be wrong on the foxboard? How could I further debug this
problem?
