Greetings! I just registered for this forum so I could post a bit more info, in hopes of leading a few more people to this thread via Google searches and such... I ran into this same problem -- new flash drives prompted for administrator credentials to install. (Actually, they seemed to function anyway, but still gave the scary admin dialog.) I followed many false trails trying to resolve this: permissions on the USBSTOR.INF file, PartMgr.sys upper filter registry entries, etc. There were lots of theories on the InterWeb about what could cause this, but not many answers. Eventually I traced it as JJA did, to an error in setupapi.log about an unsigned version of SysSetup.dll. I guess nLite created a modified version of this file, as well as sfcfiles.dll, to change some behavior during the initial installation of Windows. I didn't see any backups of the original versions of these files, but admittedly I wouldn't have known where to look. Copying clean dlls from a vanilla XP machine fixed it right up. I used nLite v1.3.5 with an XP Pro SP2-slipstreamed-on-SP1 disc as the source. I didn't change anything outside of the nLite GUI options. Despite this problem, I must say that nLite is one fantastic utility. I was able to install XP on a slew of PCs with Intel DP35DP motherboards that need SATA drivers and have no floppy controller to load it with F6 during setup. Ironically, the boards come with a floppy containing the drivers! Thanks for your hard work, and keeping up with the moving target that is Microsoft! -Warren. Wondras, Just a quick question: How were you able to find that nLite modified the sfcfiles.dll as well? Thanks, Fromthewoods

I'm assuming when you say you are copying the syssetup.dll file from the CD you mean the file syssetup.dl_ in the I386 folder. This file on the CD (at least mine) is 321KB. The syssetup.dll file under C:\Windows\System32 is 961KB. I don't think you can just copy the file and rename it and put it in the proper folder. The file size is different. Try copying it from a working system. Thanks, Fromthewoods

Hi JJA and nuhi, First off let me say nLite is a great tool and I've been using it for a few months now. I ran into this USB driver issue as well recently and thanks to JJA's work, replacing the syssetup.dll from a non-nlite'd system gets rid of this issue. As JJA mentioned above, I looked in the setupapi.log and noticed the same error regarding this .dll. nuhi: I am using a Windows XP SP 2 Volume Licensed edition hologrammed CD to create my nlite session. Once I rip all the files to my drive I use the nLite normally and create a bootable ISO. I burn it with Nero 7 and boot off the CD and install Windows normally. I have recreated my nlite'd session many times using my original CD from Microsoft and I still get this issue. Even just adding a couple of drivers to support ICH8 SATA controllers still affects this .dll. I am not sure what happens but it probably needs some attention. Please let me know if you need any more information. Thanks fromthewoods
