after starting eclipse my phone (htc desire) disconnects form my pc

My phone(htc desire) loses connection with HTC开发者_JAVA技巧 Sync, version: 2.0.33 on my laptop when I start eclipse galileo. I have windows 7 32 bit.

The followings are what I have done to solve this problem but with no luck:

1. unplug and replug the usb cable.
2. installed the old version of HTC sync
3. uninstalled the old version and installed the newst version of HTC sync.

I'v to log off or restart my laptop to be able to connect the phone with htc sync again but when I start eclipse the connection is lost again!!

any idea what would the problem be?

Thank you.

If you are losing connection to the SD card then there is no issue , this is the default behavior ( well thats is what happens on my pc) . If you want to test applications on your phone just run the app and eclipse will let you chose if you want to run the app on the phone.
