How can I tell if I have USB 2.0?

It varies, I believe. Some BIOS's have supprot for USB, but what's more common right now is that it's windows that detects the hardware (via Plug'n'play) and loads the appropriate drivers.

If other USB devices work on that computer, and only the external hard disk fails, I'd look to the manufacturer see if it needs some kind of additional support.

Hi!

I read your helpful article to check USB ports version and I confirmed that I dont't have the magic "Enhanced" word. So I have USB version 1.x..;(.

My question is: can I use a USB 2.0 device in a USB port version 1.x? Is just a question of speed or I should worry about compatible problems?

Thanks in advance,

It really depends on the device, some will, some won't.

I have the "enhanced" controller but when I plug in my IPFONES internet phone, I am told that the device is NOT connected to a high Speed USB port. I am then offered a list of high speed ports on my computer. Do you have any advice on what I can/should do? Thanks for your help

Have you tried plugging it into the other USB ports? That's what I would try.

I recently bought an used lap top computer from a person known to me. its NEC - Versa - Aptitude - PIII. since it has only 30 GB HDD, i bought a 60 GB 2.5external HDD with USB casing. but when i connected it to Laptop, it gives a message that i am connecting high-speed device into a non high-speed port!. the laptop has Intel(R) 82371AB/EB PCI to USB Universal Host Controller. Tell me what are the options available to me to use the full speed capabilities of the external HDD? can i use the pc card slot with a convertor to USB2.0 or the firewire port to convert it into USB2.0?? please tell me in detail as i am not a IT tech!
thanks & regards

Firewire is different and won't help (unless the drive you're talking about also has a firewire connection). In either case I would simply get a USB 2.0 adapter to add to your machine. Since you have a laptop, you should be able to find a PCMCIA adapter that supports USB 2.0.

In my system menu I don't have anything USB like what you have in your screencap. I have the following:

Intelr(numbers)usb universal host controller 2442
Intelr(numbers)usb universal host controller 2444
USB root hub
USB root hub

Just wondering If I have USB 2.0 as I need it for a capture card I will be purchasing (Dazzle 150)

It doesnt say "enhanced" so, I'd say you don't have 2.0.

Assuming that I have an old USB 1.1 port on my Dell Latitude C600, can I multiply it by buying a USB 2.0 4-port hub made by Belkin, Dynex, etc. ?? I know combinations of 2.0 and 1.1 always downgrade to 1.1. Does the 2.0 have to be upstream of the 1.1? My 1.1 would be upstream of the 2.0.
