unplug replug usb cable connected to modem

[Shilpa Velamuri]

Hi,

Application is talking to Telit LE910 modem over USB using libqmi with the
proxy flag to open device connection.

When i unplug and replug the USB cable connected to modem,

the callback in qmi_device_new () never gets invoked.

I need to kill my process and restart it for things to work.

If i do not unplug the USB and run through the same client release/device
close and reopen sequence, everything works just fine.

Could you help me, by telling me why qmi_device_new() callback never gets
invoked, when USB is unplugged and replugged in.

Thank You
