Hi All,

I have connected my target ARM7le, with QNX6.5.1.

And to it I have connected a Huawei Modem over USB connection.

I have a USB ECM driver from Huawei, which creates a USB ECM Interface named usb0.

However, I am unable to receive any IP address to it , when I execute dhcp.client on it.

The driver hooks into “io-pkt-v4-hc –d usbecm debug=1”

Inside Huawei modem , there is a 3G SIM card, on which a voice call is possible, but not a data call.

I have re-assured the APN settings to be correct.

According to Huawei,

There is a dhcp server running on the Huawei modem.

And on insertion of their driver, usb0 interface is created, and running dhcp.client acquires public IP from dhcp server running on Huawei modem.

But I am unable to get an IP address on the interface, it’s all 0.0.0.0

Along with this tcpdump output for this interface is empty.

And all my other Ethernet interfaces disappear from target after insertion of the ecm driver.

I don’ understand what the problem is.

Huawei saying that this works at their end, and they are helping me to debug this up-front.

But I just wanted to know if anybody has any ideas on this, so that it could be accelerated.
