TUSB7340 used for AMI BIOS

Other Parts Discussed in Thread: TUSB7340

Dear Sir

I use TUSB7340 with Baytrail platform ,However AMI BIOS have a release note that when user install Win7 OS ,it have to disable XHCI and EHCI ,If disable XHCI ,user can't use TUSB7340's USB port to install Win7 OS by USB CDROM

Have any idea or experience about this issue? Thanks 

Below is AMI BIOS release note :

About Win7 Install Information

Please check those configuration.

I.Token = "CSM_SUPPORT" "=" "1"

II.Check your VBIOS is correct and launch legacy OpROM only

III.Check Usb mode for EHCI and XHCI disable

IV.Setup page Advanced->OS Selection->Windows 7.
