@ AYHJA:
I found an article, linked here (<a href="#article1">1st article</a> embedded below), that describes a procedure for removing USB drivers. Needless to say, telling windows to delete anything system related has me worried, let along the USB peripheral devices, HID and/or Composite USB, USB Root Hub(s), and USB Host Controller(s).
Sony's EU Customer Support describes the exact same procedure (<a href="#article2">2nd article</a>).

Cleanup Windows Device Manager
12/14/2005
by USBMan
Cleaning Up the Device Manager while running in Windows Safe Mode is the first step in resolving hardware conflicts in Windows.
Win9X - The following procedure can resolve Windows conflicts by removing redundant and/or obsolete device entries that are installed in virtual mode.
WinXP and 2000 - Removing USB devices in Safe Mode will force the OS to refresh the USB driver stack and may cause a shift in IRQ assignment.
Enter Windows SAFE MODE by holding down the F8 or Ctrl key just before the Windows Graphic User Interface, (the colored start screen or GUI), displays on the monitor. If you see the Windows GUI you missed your opportunity and you will need to cycle through, shutdown and try again.
When the Start Up Menu appears choose (SAFE MODE)
Windows will inform you that you are in SAFE MODE. If you are using a USB mouse you may not have mouse support.
Note: Completely removing USB creates problems for users who have both USB keyboard and mouse connected. When you reboot to Windows Standard Mode, NO input device is recognized making it impossible to continue. To prevent this from happening, change one input device to PS/2 until you have completed the cleanup.
Using the TAB, ARROW keys, CTRL, ALT and ENTER, navigate through START, SETTINGS, and CONTROL PANEL to SYSTEM

Using the arrow keys, go to each and every category and remove any and all redundant and/or obsolete device entries that you find there. Remove both copies of the duplicate entries. When you reboot, Windows will recognize the device and reinstall a single driver.
Note: Always reboot to Standard Mode and then recheck the Device Manager in Safe Mode after adjustments have been made. Windows has a habit of installing and reinstalling duplicate devices in virtual mode.

Removing USB Completely
If USB is sharing an IRQ with another device and you are attempting to free the IRQ, or you need to refresh the USB driver stack, you must remove ALL USB elements completely. Windows will refresh the USB driver stack when you reboot to Windows Standard mode..
Note: Completely removing USB creates problems for users who have both USB keyboard and mouse connected. Change one input device to PS/2 until you have completed the cleanup.
Refreshing the USB Driver Stack
Windows Standard Mode
*
Unplug all USB devices except keyboard and/or mouse.
*
Uninstall the software for the USB peripheral devices.
*
Shutdown and boot to Safe Mode -> Device Manager
Windows Safe Mode -> Control Panel -> System Properties -> Device Manager. In the view Tab Select the Show Hidden Devices Option
The order of removal must be followed exactly
*
Delete USB peripheral devices (Scanners, Printers, Cameras etc.)
*
Delete HID and/or Composite USB (Human Interface Devices)
*
Delete USB Root Hub(s) (Universal Host Controllers)
*
Delete USB Host Controller(s) (Universal Host Controllers)
Note: You can Navigate in Safe Mode using the keyboard Tab, Alt, Crtl and Arrow keys.
The Universal Serial Bus Controller and Human Interface Device headings should disappear completely from the Device Manager. Before rebooting to Windows Standard Mode, insert the Windows CD into the CDROM drive and direct Windows to look in, (Example D: / Win98, where D is the letter of the CDROM drive on your system), Win9X folder on the CDROM when/if prompted.
UNPLUG ALL USB DEVICES BEFORE BOOTING TO WINDOWS
USB Does NOT like to share it's IRQ with another device especially when the user is employing sophisticated USB peripherals. Even though Windows may report NO conflict, if USB is sharing its IRQ with another system peripheral, (i.e. video, sound, SCSI etc.), that is often the source of the problem. (IRQ Holder for PCI Steering is NOT considered another device)

Removing USB entries from the Windows Device Manager
\
by Sony
Cleaning up USB can only be done when your computer is in SAFE MODE.
* Windows 98 - The following procedure can resolve Windows conflicts by removing old/unused device entries that are installed in virtual mode.
* Windows XP and 2000 - Removing USB devices in Safe Mode will make the OS refresh the USB driver stack and may cause a shift in IRQ assignment.
Microsoft Windows 98 Startup Menu
1. Normal
2. Logged (\BOOTLOG.TXT)
3. Safe mode
4. Safe mode with network support
5. Step-by-step confirmation
6. Command prompt only
7. Safe mode command prompt only
Enter a choice: 1 Time remaining: 06
To start Windows in SAFE MODE:
1. Press the F8 or Ctrl key just before the Windows logo appears.
2. When the Start Up Menu appears, select SAFE MODE.
3. Windows will inform you that you are in SAFE MODE.
4. If you are using a USB mouse you may not have mouse support.
NOTE: If you remove the USB entries completely then it may create problems for the users who have both USB keyboard and mouse connected. Connect at least one PS2 device (mouse or keyboard) that will enable you to browse the device manager.
Removing USB Completely
If USB is sharing an IRQ with another device and you are attempting to free the IRQ, or you need to refresh the USB driver stack, you must remove ALL USB elements completely. Windows will refresh the USB driver stack when you reboot to Windows Standard mode. In Windows Standard Mode (when the computer has started normally, no Safe Mode)
* Unplug all USB devices except keyboard and/or mouse.
* Uninstall the software for the USB peripheral devices.
* Shutdown and start Windows in Safe Mode - Device Manager
* Restart Windows in Safe Mode - go to Control Panel - System Properties - Device Manager.
* In the View Tab, select the Show Hidden Devices Option
