iMac Pro review
I used to have evidence in 'device manager' that I had usb 2.0 available on my system, ASUS A7N8X2.0 motherboard with XP home and service pack 1 installed.
Since having to re-install XP as a result of a virus, which wiped out my restore points, I seem to have lost 'other devices' in device manager. According to the m/b cd, this is required to enable usb 2.0.
In device manager I have these settings under Universal Serial Bus Controllers
1* standard enhanced pci to usb host controller and
2* standard openHCD usb host controller
with 3* usb root hub
I'm possitive that before my virus, it mentioned usb 2.0 in usb controllers and now it doesn't.
My m/b should be able to support 6* usb 2.0 devices but I don't think my system is set up correctly.
I really don't understand any of this so simple advice would be appreciated.
I downloaded service pack 1 from the m/s web site.
In 'general', control panel, system, it says XP home edition version 2002, service pack 1.
That will rule out the theory I had then! XP with SP1 will/should recognise USB2 and show it in device manager under usbc as you say. But I have just had a look in my "Device manager" I have 10 ports, 8 of them USB2, all are listed as USB. No indication of speed is given. j.
I should have 6 usb ports available but are shown as 3 * usb root hubs and 3* host controllers. Is this just the 3 ports or are they just different ways of saying the same thing, i.e. 6 ports alltogether?
Also, I believe that the 'enhanced' PCI to usb host controller reflects that it is usb 2.0. If this is so, does this mean that the 'standard' usb controllers are usb 1.1?
Thanks for your help Djohn, it is much appreciated.
*standard enhanced pci to usb host controller* is the USB2 controller, also 3 usb root hubs and 3 host contollers have 2 ports each which give you the 6 you have.
From the little I know on this subject and from looking at my own listings, I would say that you are correct In saying:
"i.e. 6 ports alltogether? Also, I believe that the 'enhanced' PCI to usb host controller reflects that it is usb 2.0".
Others will correct me on this though if I have made a mistake. Regards j.
Many thanks, I posted before doing a refresh and missed your reply. j.
So, if 'standard enhanced pci to usb host controller' is usb 2.0, does this mean that the other ports, both 'standard openhcd usb host controllers', are not usb 2.0?
If this is so, how do I change then to usb 2.0?
Thanks for your input The Sack and once again Djohn.
Not realy sure on this one and just a guess! Is your system made up of 2 USB connectors on the board and 4 from a PCI card? If so, then I would say yes, they are all USB2. But once again others will confirm. Regards. j.
This was written before i saw the replies,sorry i was late.You board?.
Back Panel I/O Ports 1 x Parallel
1 x Serial
1 x PS/2 Keyboard
1 x PS/2 Mouse
1 x Audio I/O
4 x USB 2.0 you supplier likely added 2 more?
Internal I/O Connectors 1 x USB 2.0 connector support additional 2 USB 2.0 ports Industrial Standard PCI 2.2, USB 2.0
as Djohn has said,confirmed below. Do go to System's information via the start,programs,accessories,systems tools,then open up the components tab,go to USB which should confirm or not that you have the following VIA USB 2.0 Enhanced Host Controller or similar.
Microsoft Win XP USB 2.0 drivers are included in Service Pack 1.
The final release version of the Microsoft USB 2.0 drivers for Windows XP is available at the Windows Update Site. The driver is designated Microsoft USB Driver Version 5.1.2600.0. USB 2.0 Drivers are included in Service Pack 1.
You can get them from the MS site by going to
Microsoft in its infinite wisdom has made it impossible for end-users to download the individual driver package of USB 2.0 drivers for Windows XP. If you need the USB 2.0 drivers, MS now requires you to download and install Service Pack 1. This is the only way to get the drivers from Microsoft who promised USB 2.0 support to everyone who purchased Windows XP.
