How can I tell if I have USB 2. Trying to install USB 80 external hard
drive. Have a firewire. I need a 1394 Cardbus. How do I find out if
that is on my computer?

Hello.

From Iomega:

"How do I know if my computer has USB 2.0 or USB 1.1 support?"

For Windows 98/ME:

"1. Right-click the My Computer icon and select Properties.
2. Click the Device Manager tab.
3. Click the plus (+) sign next to Universal Serial Bus Controllers.

...If Enhanced Host Controller and/or USB 2.0 Root Hub Device is
listed, then the computer has USB 2.0 ports."


For Windows 2000/XP:

"1. Right-click the My Computer icon and select Manage.
Note: Windows XP users may need to click Start to access the My
Computer icon.
2. Click the Device Manager icon.
3. Click the plus (+) sign next to Universal Serial Bus Controllers.
...If Enhanced Host Controller and/or USB 2.0 Root Hub Device is
listed, then the computer has USB 2.0 ports."

Additionally, a newsgroup message mentions a utility called Sandra
that will detect USB 2.0.
