USB modem works only after reinserting twice.

I  have a strange issue with my Arch Linux setup and ZTE WCDMA modem. I recently bought this modem and trying to connect to internet through wvdial. I initially thought that modem is not being detected under Arch Linux (as it was working fine under Ubuntu and Fedora). Later on I understood that the vendor/ product id is changing when I reinsert the modem. For example, When I insert the modem immedietly after boot, the following is shown as vendor/ product id and modem does not connect to internet:-

[sundar@arch ~]$ sudo lsusb
.
.
Bus 001 Device 008: ID 19d2:fff5 ZTE WCDMA Technologies MSM 

Then I have to remove and reinsert the modem. This time device indicator (kde) and dolphin will show as another partition and vendor/ product id will change to following:-

Bus 001 Device 007: ID 19d2:fff1 ZTE WCDMA Technologies MSM 

And without any issue modem will connect to the internet through wvdial. How do I over come this issue and connect to internet directly without removing modem?
