Hi,
I am trying to use a SMC2862W-G USB WiFi dongle with the beagleboard. This WiFi dongle uses the ISL3887 chipset, and thus is supported by the p54 drivers included in the Linux kernel. I have read the following websites in order to learn how to port drivers over, including
- http://processors.wiki.ti.com/index.php/TI-Android-GingerBread-2.3.4-DevKit-2.1_PortingGuides#WLan
- http://blog.linuxconsulting.ro/2010/04/porting-wifi-drivers-to-android.html
I have made all the necessary changes to the code, and built the p54usb.ko kernel module to be loaded. Once the Android system is completely started up, I type at the command line: 'insmod p54usb.ko'
Here is the log output that I'm getting:
# ls
p54usb.ko
# insmod
usage: insmod <module.o>
# insmod p54usb.ko

I'm failing to understand what is going wrong here. It seems like the ieee80211 is unable to connect to the device because the usb bus keeps resetting the device. why would this happen? I'm at a loss as to how to proceed in order to get this wifi module working with beagleboard. I have the same problem when I try to turn on wifi from the gui.
I have verified that the wifi dongle is functional by plugging it into my ubuntu machine, it works fine and in fact uses the same firmware and driver that I built with the Android Kernel.
Thanks in advance,
Kiran
