Windows 7 was not loading the USB 3.0 Drivers. I downloaded the drivers from here: ftp.dell.com/.../xps-l502x.html I required two driver, both were located in the /files/x64/ directory.
Tl;dr USB Ports stop working after booting Recovery Disk and Norton Ghost. Long version. I have a Dell Laptop XPS 15. The hard drive recently died. I have a recent back up on a WD Passport I created using the Windows 7 Backup and Restore “Create a system image.” I also have a “system repair disk.” Old hard drive ~680MB new hard drive ~1000 MB I followed the instruction in the user guide, removed the old hard drive, and replaced it. I booted the Laptop from the system repair disk, but it does not see the backup image. In fact, it doesn’t see the USB hard drive at all. I used the command prompt to attempt to switch to the e:\ drive, no go. I used DISKPART to “list disk” and it only shows the internal new black hard drive. I got the driver from WD “WDAPPs_Windows_Disk_Image_PPWINOXR2A_1_0_0_18A.zip” and unzipped it and burned it to CD. Used the “load driver” option, but the only “Setup Information” file (wdcsam.inf) did nothing. I took the external USB WD Passport Hard drive to another computer to ensure the backup was truly there and it was. WindowsDiskImage is in the root and I’ve made no changes after Windows Backed up the Image. I plugged the USB WD Passport Hard drive back in and pressed F2 to get to the BIOS. On the boot order screen I can expand the USB Storage and it shows ~WD Passport. So the BIOS see the HD. After all the trouble I decided to just load windows and use the restore function in windows. I put in my USB Thumb Drive with Norton Ghost and booted to the Thumb Drive. Ghost loads off of the USB. But when I browse for the Image, my Dell does not see the USB thumb drive. It boots to it, but it does not see it in the file structure. In other words, after I boot to the recovery CD or boot to a thumb drive, the computer no longer recognizes devices plugged into the USB ports. Please help and thank you in advance.
