Did you try it in this exact order?

 

 

Disconnect your printer. Download and run this patch to completely remove the printer from your computer.

 

Restart your computer.

 

Go to device manager.(right click my computer, left click preperties, left click hardware, left click device mananger)

 

Go down to the USB Controller section and click the + sign. Starting at the bottom, USB Root Hubs, and working your way to the top, USB Universal Controllers, un-install everything in that section.

 

Restart your computer. Windows will find them all again and correct the one with the problem. Please be patient, the new hardware wizard will work 3-5 minutes before it's done. 

 

Download the proper drivers.

 

XP Drivers

 

Vista 32-bit Drivers

 

All other drivers

 

Install the proper drivers. You'll be prompted when to connect your printer(powered on)

 

Please remember to install the latest firmware for the A960 Printer. (Message edited to include this)

 

 

Scanning

 

Scanning using USB connection, open the Dell All-In-One Center, click on scanning and copying and scan from there.

 

Scanning wirelessly, use the scan buttons on the printer.

I'd already downloaded and installed multiple times the remove printer patch, newest driver and latest firmware. However, I'd not seen instructions about removing the USB controller hubs and controllers in the device manager. I followed the instructions exactly to remove the printer using the Dell CleanUp Utility before rebooting. Then I went to work on the USB devices.

 

The following were listed in the USB section:

Generic USB Hub

Standard Enhanced PCI to USB Host Controller

Standard Open HCD Host Controller

USB Root Hub

USB Root Hub

 

The first time I tried to uninstall from the bottom of the list, the device manager window "flashed" information while attempting the uninstall of USB Root Hub. In the end it was only possible to remove one of the last two "USB Root Hub" entries, so I removed to the Standard Open HCD Host Controller and the Standard Enhanced PCI to USB Host Controller entries. When these were uninstalled, all the entries disappeared. 

 

After rebooting, I got only the first 4 listed:

 

Generic USB Hub

Standard Enhanced PCI to USB Host Controller

Standard Open HCD Host Controller

USB Root Hub

 

When I started uninstalling from the bottom, everything went fine this second time. I rebooted again and then started reinstalling the driver. Everything seemed to go fine including plugging in the USB cable for the turned-on printer when I was prompted. However, as in all the multiple attempts to install the driver, at the end, the option to start the All-in-One Center software was greyed out because the fax/scanning software didn't install. Printing works fine, but without the AIO Center software it isn't possible to setup scanning.

 

I have an HP Pavilion tx1000 with Windows Vista Home Premium (32 bit) and am connected to the A960 with a USB cable. I am using Symantec Endpoint Protection v. 11.0.2010.25.

 

Do you have any other suggestions?

 

Since you did have a usb problem before and it got corrected, try this one more time.

 

Disconnect the printer, run the patch, re-install the proper drivers, connect printer when prompted.

 

What do you get now?

Try calling Dell Tech Support and request one. You may need your service tag number located on the back of the printer.

I went through the Cleanup-the-computer/uninstall-the-printer process, rebooted, and installed the driver with the Symantec Endpoint Protection turned off (always worth a try). This time the print-a-test-sheet window didn't appear with the greyed-out AIO-center-software line. However, there is no AIO Center software in All Programs so I'm no further ahead.

 

Will Dell supply a replacement installation disk? Does it contain anything different than the driver which doesn't install?
