Samsung Galaxy Tab 8.9 Can Not Connect to Kies via USB

I have a very frustrated experience with Samsung Kies. I could not connect my samsung galaxy tab 8.9 to Kies, it will only stay at connecting.

I have double confirmed this:

1. Device is not rooted
2. USB debuging OFF
3. Reinstall driver
4. Turn wifi off, take out Memory card ( even i don't have) and ... bla bla bla

Finally, this solve my "connecting" problem by just disable the pattern unlock function.

Then, i got another ERROR, which is "cannot start service on the device. please disconnect then reconnect the device". It make me mad, and the only solution worked is, FACTORY RESET my tablet.

I really wish Samsung can invest more on their software (Kies and firmware update).
