To solve the problem, do as follows:
1. Remove the data card and re-insert it.
2. If the problem persists, make sure that the drive is installed by following the
normal installation procedure. If the drive is installed manually, ensure that
autorun.exe is the first program to be run. If the installation fails to meet the
requirements, uninstall and then reinstall the Mobile Partner.
After I access or search the 2G network, the USB channel is blocked.
What should I do in this situation?
Remove the data card and then re-insert it or use another USB port.
