Windows 7: USB Mass Storage Issue Windows 7 x64

Thanks for the welcoming and advice. However, my USB-devices have been working fine on my computer while I was running windows XP so the USB bus should be good enough.

Having run the system file checker and found errors plus not having problems while XP was on only leads back to one thing namely the 7 install itself was incomplete or simply put a bad install to begin with. You may end up needing to perform an upgrade to repair or even full clean install to solve this since we've already covered the other mostly likely other causes.

I had this precise problem and I fixed it by restoring \WINDOWS\INF from a backup.

Was that with the original Fat 32 factory partition or did you reformat it to NTFS before placing any files on it?

For XP and Vista the software installer was always seen when plugging in the first external HD bought here until simply nuking all that off and running it with the native NTFS volume. With the exception of writing GParted or installing a live distro onto flash drives I do the same for those as well.

Sorry it took so long to post this final part.

Well my issue was finally resolved with a complete reload. The SFC scan I ran which I posted earlier did show some bad files. The problem I had was the media I had downloaded also had the same bad files. I was unable to restore the files from the DVD as it told me the store was also corrupt. I borrowed a friends DVD and attempted to perform a repair but was not permitted to do so as it could not validate if I was using bit locker. I suspect this was related to the corrupt files. After reloading my system works great! My USB devices work as expected and mass storage is functioning. I ran an SFC again and it gave me a clean bill of health. I would recommend that anyone with this issue run SFC and rule that out first.

Thanks for all who helped me out!

Sorry about the delay in getting back to you.

My system was NTFS from the factory.

I just pulled the \INF directory from a DriveImage XML backup and merged it with the existing one, and that solved the USB mass storage class issue. For me anyway.

So there was no reformatting to do or anything like that.

The reason I mentioned that is many models are compatible for both Windows and Mac where they come with a Fat 32 volume on them instead. That will then see a software installed in order to run the drive on the other OS as well as on XP, Vista. 7 saw the return of support for Fat and exFat volumes.

Most usb flash drives will typically Fat 32 on them as well.

At least you found the solution there however. Now get busy backing things up!
