New USB PCI card installed but devices still running on 1.1 not 2.

I have just added a new PCI card to my PC (XP SP-2) to add more ports and
upgrade to USB 2.0. Previously everything was running on version 1.1. In
device mananger I now have two listings for USB controllers but all my USB
devices are listed under the original one and not the new USB 2.0 root hub
device list.

List 1.
Intel USB Universal host controller
NEC PCI to USB internal host controller (listed twice)
Connected devices

List 2.
NEC PCI to USB enhanced host controller
USB 2.0 root hub device


Do I manually have to somehow update each USB peripheral device (card
reader, printer etc.) to use USB 2 instead of 1.1?

Thanks.

If your devices are USB 1.1, then to take advantage of USB 2.0 requires and
upgrade. Note that the USB hardware will throttle down to USB 1.1 if the
device cannot support USB 2.0.

Did you connect the devices to the new controller or leave them connected to
the old controller? For them to work as 2.0 they need to be connected to
the 2.0 ports on the new device controller.

When you connect the devices to the new controller you should see "New
device found" dialog and a request for the proper drivers for the device
even though they had been installed on the old device controller.

No - but the 1.1 controller is not magically transformed to USB 2.0.
Check the drivers on your #2 there, d-click in Dev manager, Drivers,
list driver, and usbehci.sys is the USB 2.0 one.

The enhancement relates to the 'Root hub' concerned. D'click each of
these; Power will tell you the devices connected, driver details again
whether it is using USB 2.0 (and some cheap PCI cards only provide USB
2.0 on some of their ports)

Oops - sorry, Driver details there does not tell you.

Also you will not get USB 2.0 in action unless the device itself (and
any intermediate hub) is USB 2.0. Possible for very recent scanners,
likely for Cameras and camcorders, very unlikely for printers that just
do not need that speed
