OK, I used nlite to inject the USB3 Drivers, and then I edited TXTSETUP.SIF adding these manually [BootBusExtenders.Load] nusb3hub = nusb3hub.sys nusb3xhc = nusb3xhc.sys [BootBusExtenders] nusb3xhc = "Renesas Electronics USB 3.0 Host Controller",files.none,nusb3xhc nusb3hub = "Renesas Electronics USB 3.0 Root Hub",files.none,nusb3hub Seems to be working now, it's seeing my USB So one last question, does anyone know what to add to a TXTSETUP.OEM file so that it will add those lines to BootbusExtenders automatically? heres my revised TXTSETUP.OEM [Disks] disk1="RENESAS USB3 Installation Disk",\nusb3xhc.inf,\ disk2="RENESAS USB3 HUB Installation Disk",\nusb3hub.inf,\ [Defaults] SCSI=nusb3xhcx86 [SCSI] nusb3xhcx86="Renesas USB3 Driver x86" nusb3hubx86="Renesas USB3 HUB Driver x86" [Files.SCSI.nusb3xhcx86] driver=disk1,nusb3xhc.sys,nusb3xhc inf=disk1,nusb3xhc.inf catalog=disk1,nusb3xhc.cat [Files.SCSI.nusb3hubx86] driver=disk1,nusb3hub.sys,nusb3hub inf=disk1,nusb3hub.inf catalog=disk1,nusb3hub.cat [HardwareIds.SCSI.nusb3xhcx86] id="PCI\VEN_1033&DEV_0194&REV_03","nusb3xhc" id="PCI\VEN_1033&DEV_0194&REV_04","nusb3xhc" [HardwareIds.SCSI.nusb3hubx86] id="NUSB3\ROOT_HUB30","nusb3hub" id="NUSB3\CLASS_09&SUBCLASS_00&PROT_00","nusb3hub" id="NUSB3\CLASS_09&SUBCLASS_00&PROT_01","nusb3hub" id="NUSB3\CLASS_09&SUBCLASS_00&PROT_02","nusb3hub" id="NUSB3\CLASS_09&SUBCLASS_00&PROT_03","nusb3hub" [Config.nusb3xhc] value = Interrupt Management\MessageSignaledInterruptProperties,MSISupported,1,0x00010001,1 value = "", ErrorControl, REG_DWORD, 1 value = "", Group, REG_SZ, "Boot Bus Extender" value = "", Start, REG_DWORD, 0 value = "", Type, REG_DWORD, 1 [Config.nusb3hub] value = "EventMessageFile",0x00020000,"%11%\iologmsg.dll;%12%\nusb3hub.sys" value = "TypesSupported",0x00010001,7 value = "", ErrorControl, REG_DWORD, 1 value = "", Group, REG_SZ, "Boot Bus Extender" value = "", Start, REG_DWORD, 0 value = "", Type, REG_DWORD, 1 just wondering what to add to it so it will add the lines to BootbusExtenders Automatically Thanks for the help
