Josh thanks for your help.
I have try with "-I and -n" but it still cannot change to modem.

I have the same dongle.
I try switch to modem with usb_modswitch(1.1.3) successfully in ubuntu 10.04.
However, it's fail to change in the embed system: mips and linux2.6.21.

I ask a simple question.
Does usb_modswitch support this device aireplus MCD-800 now? Thanks.

Thank you Josh.
I have try to find "06 1b" in the UsbSnoop.log but I can't find it.
