hi

hope in correct section.

now i have no idea how to tell what USBs i have, i'm sure i have USB 1.1 but do you tell if you have any USB2.0????

i looked in control panel and found:

eHome Infared Reciever (USBCIR) (Manufacturer: Microsoft)
Standard Enhanced PCI-USB Host Controller (2 of these) (Manufacturer: Standard USB Host Controller)
Standard Universal PCI-USB Host Controller (5 of these) (Manufacturer: Standard USB Host Controller)
USB Composite Device (Manufacturer: Standard USB Host COntroller)
USB Mass Storage Device (Compatible)
USB Roots Hub (6 of these) (Standard USB Host Controller)

I've been into the properties of each and tells me nothing about if its USB 1.1 or 2.0.


be great if someone could help me out.

i bet they are all 1.1 i'd have to go and get a USB 2.0 somehow. the computer is 6 months old.

Pentium D 2.8Ghz
2GB Ram
160GB hardrive
256MB Graphics (intel)
Vista Home Premium (base score 3.5)

The easiest way to tell is plug a USB 2.0 device (Digital Camera, External Hard Drive, iPOD, New MP3 player)in and see if Windows brings up a little pop up that says "This Device Can Operate Faster" (It'll be near the Clock in the Lower Right Side of the screen) If it does then that Port is a USB1.1 if not its a 2.0.

Another way to find out just about everything about your computer, is to download SIW (System Information for Windows) and run it. No installation is needed so it may be run from anywhere you choose.

In the left hand pane, go to Hardware>Ports>USB. The first entries in the right hand window will tell you which types of USB are supported.

You can get SIW from here: http://www3.sympatico.ca/gtopala/about_siw.html

i remember a while ago about something about "This device can perform faster" but can't remember what it was now.

Got the program and the first two says:

USB 1 Supported
USB 2 Supported

So i presume it has USB 1 & USB 2???

almost all usb1 devices can run on usb2 ports, however some may have a problem, rare, bios used to come with settings to turn off usb2 for certain ports

never had any problems myself, beyond the fact that usb is a system intensive bus

Yes Izzy. You can run either on your computer.
USB 2.0 has been around for quite a while, so any reasonably new computer will run those devices.
Re SIW. Take the time to browse through the list in the left hand pane, and you will find out just about anything about your computer. It is a great way to learn.

Have fun :thumbsup:
