I did 'rmmod pl2302' because I could not find plc2303 module. The drect
result of above two commands, is /dev/ttyUSB0 disappeared.

WvDial<*1>: WvDial: Internet dialer version 1.56

FYI: the product is by Huawei, not by Qualcomm, Inc. Though I am not
sure if they rebranded it, but Huawei is one of the biggest manufacturer
in China and is likely to have their own product/chips.
