Hello,
I'm trying to use a USB Wifi module on a linux 2.6.33 kernel using
powerpc architecture. The Wifi module is a UNEX DNUA-81 based on an
AR9170 from Atheros.
My problem is that the firmware provided by Atheros can't get uploaded
into the device.
I have tested the same driver and firmware on an X86 platform, it works
fine.
Please find at the end of the message, an extract of what dmesg after
plugging the device.
For what I understand, the driver wants to use the ep_00 device to
transmit the firmware, but this device isn't initialized when it try to
begin the transfer. Is this correct ?
Any idea on how to solve this ?
Regards Sebastien
