Hi all,<br>
<br>
I'm having a problem with my 3G USB stick (Huawei E220) .<br>
<br>
The kernel I'm using is version 2.6.21 customized for an ARM board. When<br>
I insert the USB stick into the system, normally 3 device show up:<br>
/dev/ttyUSB{0,1,2}. The problem I' having is that some time, only the<br>
first one shows up and I cannot connect to it. When this happens,<br>
normally a reboot will fix it.<br>
<br>
As I said, this sounds like a kernel/driver issue to me. Could somebody<br>
give me some pointers as how to prove/fix it?<br>
