How can you tell if you have USB 1.0 or 2.0?

On what?

 

[Wim Cossement]

By checking the chipset, or via the Device manager in Windows

OK. So what do I look for in the Device Manager that would tell me?? I've
already looked, and nothing actually says "USB 1.0" or "USB 2.0."

2.0 = enhanced. Otherwise it's 1.1

A non-technical way is to plug a device you know is designed for USB 2.0
into your computer (such as a modern USB memory stick). If Windows
complains about a "HI-SPEED device plugged into a non HI-SPEED port",
you have USB 1.0. If there is no message, USB 2.0.

I've not seen that with a USB2 memory stick or a USB2 drive caddy, so I
wouldn't bank on it.

Look in device manager and google for whatever USB chipset is reported, or
measure throughput of a USB drive using perfmon, or look in the motherboard
manual, or look at the specs on the manufacturers website.

Meh. It happens to me all the time with my computer at work.

I'm curious - as I work with a variety of kit and haven't seen this - I
suspect that it's something particular to either the device driver or the
chipset driver. What devices are you using? I would guess that if the device
is something that absolutely requires USB2 bandwith - then it would be
sensible for the driver to complain.

Lookee here: http://hogranch.com/files/Bitmaps/USB-device-manager.png

Here you can clearly see the USB contoller with other hardware attached.

If you don't see something like that, the right driver might not be
installed and you'll see it as an 'Unknown device', a questionmark icon.

Also, if you can see the chipset type (like Intel 82801DB), you might
find something on the site of the manufacturer, or just try searchin the
Web.

Also, make sure you have the 'Show devices by connection' enabled in the
View menu.

As far as I can see [for USB] Everest reports just the same info as does
device manager - it doesn't seem to have any additional info. IT's still a
good program to have though.

Two things: a standard memory stick and an MP3 player. They are both USB
2.0 devices, but when I plug them into my Windows XP system a little
bubble appears on the taskbar complaining about my fact that they were
plugged into USB 1-only connectors.
