USB1 or 2 - how to tell?

[Jeff Layman]

I recently added a USB2 PCI card to my USB1 motherboard. XP (SP2) detected
it and apparently installed it ok. The device is there in "Computer
management", but it just says "ALi PCB to USB Open Host Controller" - there
are no "USB2" devices under "Universal Serial Bus Controllers". The drivers
associated with the card (.../System32 folder) are all named usbxxxxx.sys
(all dated 03/08/04). How can I tell if these are USB2 drivers or not?

TIA

Does the word "Enhanced" appear anywhere?

 

[Jeff Layman]

Yes - only once, in "Standard enhanced PCI to USB Host Controller". But the
driver for that is Bonifay.sys, which is a Freecom driver (I assume for my
Freecom external USB2 drive). That driver also appears to be associated
with all the other USB devices (but then so are several usbxxxxx.sys
drivers).

I should say that a 55 Mb folder (OE6 *.dbx files!) was copied from my C:
drive to the External HD in 15 seconds. That seems faster than a USB1 link.

For XP and above, there are three inbox miniport drivers for the USB
controller, usbehci.sys, usbohci.sys, and usbuhci.sys. These drivers are for
support of controllers supporting the enhanced host, universal host, or open
host controller specifications respectively. Look for your controller in the
device manager tree and check the driver list. If you see usbehci.sys
listed, it is 2.0. Based on the information you provided in your post, you
should also see the usbohci driver since your controller supports OHCI.

Yes, thanks for the info. I do have usbohci.sys as a driver for ALi PCI to
USB Open Host Controller, but not for Standard Enhanced PCI to USB Host
Contoller (that has usbehci.sys).

OK, I'm happy now that I do have USB2 working!
