Hi all
 
I compiled a DarwinFox image from SDK with kernel version 2.6.25.20 to my FoxBoard 832. I tried to make a gprs connection with my mobile phone connected to ttyACM0 and I get strange errors, like this:

ifconfig shows only eth0 and lo. What is the problem?
I also tried with Huawei E220 HSDPA modem with kmod-usb-serial-option package installed, same problem! This mobile phone I used has worked with FoxServe firmware installed. My goal is to get the Huawei E220 modem working. Or some other 3G modem if there are better than E220.
Is E220 a good choice?
