HTC Wildfire Plugin for debugging not working in UBUNTU

Question

I got this following devices :

1. I got my Ubuntu 64 bits PC
2. I got my Wildfire (not S, but normal Wildfire)

In my phone, I have turned on:

1. USB debugging mode
2. Also in the charging mode

However, ECLIPSE didn't find my device in their DEVICE section. So, I am wondering for the ideas ! :)

Thank you !
