Problem with USB v2.0 for CDC Serial Demo Code

I'm having a real problem with the code on cdc-serial-demo. I'm trying to configure the device descriptors on cdcs_usb_config.c specifically on the USB version part. The default is 0x0110 for USB ver1.1 but I want to make it 0x0200 for USB ver2.0. However when i tried this, a "!" symbol on the com port where the USB is connected appears and says
 
The device cannot start.(code 10)
 
So what seems to be the problem for this? Do i need to add additional codes or does the .inf file has something to do with this?
 
Please help me on this guys.
 
Thanks!
