Subject: likely kernel/driver problem with 3G USB stick
Date: Tue, 01 Mar 2011 16:10:43 +0000	[thread overview]
Message-ID: <4D6D1A83.7000907@gmx.com> (raw)

Hi all,

I'm having a problem with my 3G USB stick (Huawei E220) .

The kernel I'm using is version 2.6.21 customized for an ARM board. When 
I insert the USB stick into the system, normally 3 device show up: 
/dev/ttyUSB{0,1,2}. The problem I' having is that some time, only the 
first one shows up and I cannot connect to it. When this happens, 
normally a reboot will fix it.

As I said, this sounds like a kernel/driver issue to me. Could somebody 
give me some pointers as how to prove/fix it?


Thanks,
