USB 2.0 query

I am using Win 98se with USB 1.0. I've just installed a PCI card with 5 USB
2.0 sockets. It seems to have installed OK but is there a way to test that
it's working as Ver 2.0 and not ver 1.0 ?


Regards and thanks in advance

When you have a device that can communicatie faster than 11Mb/s (1.4MB/s),
an external harddisk for instance, and you can proof that it really does
communicate faster, it's 2.0.

USB1 uses 11 megabits/sec (Mbit/s) transfer rate that is
1.1 megabytes/sec. USB2 is much faster - 400Mbit/s

If you have an Enhanced Host Controller listed under USB
Controllers in the Device Manager, the controller will use
the correct mode for the device.

See this page: http://www.pcbuyerbeware.co.uk/USB.htm

If you don't have an Enhanced Controller, you should try
downloading the latest updates from the PC's motherboard's
site, one of which should be a USB Controller.

Use this free utility to ID the motherboard if necessary:

Yes, the enhanced driver must be installed for USB to work in 2.0 mode.
You need a USB 2.0 device to establish its operability though. Such a
device that will work in USB 1.1 or 2.0 enviironment can be used since he
had both type ports. A scanner or HD will show a dramatic performance
difference between the two different type USB ports. Scanner must use same
scanner settings etc for comparison. Use benchmark software for comparing
using a HD, cached files to memory may require a reboot for fair comparison
of alternate USB port.
