I am using Windows 7 and would like to see which USB versions each attached USB device is using (1.1 or 2). How can I do this?

Speed and USB version are not the same thing. USB 3.0 supports 4 different speeds, for instance: en.wikipedia.org/wiki/USB#Transmission_rates tr1.cbsistatic.com/hub/i/2009/12/22/…

You can determine the USB specification that a device supports by examining its bcdUSB field. It is not stored in the registry, so you cannot just search or access it. It is stored on the device itself, so you need a way to query the device to retrieve it.
You can use the USB View utility from Microsoft. It is available on the installation CD of some versions of Windows (and possibly some old versions of the Resource Kit). I’m not sure if it's legal to distribute it, but it’s certainly easy enough to find a copy. You could also use the commercial program USBlyzer.
The
bcdUSB field is a hexadecimal number that will indicate the highest USB version the device supports in a packed-decimal format:0x0100 = USB 1.0
0x0110 = USB 1.1
0x0200 = USB 2.0
0x0300 = USB 3.0
In addition, you can view the actual speed the device supports in the Device Bus Speed field:
Low Speed : <= 1.5 Mbps (USB 1.0+)
Full Speed : <= 12 Mbps (USB 1.0+)
High Speed : <= 480 Mbps (USB 2.0+)
SuperSpeed : <= 5.0 Gbps (USB 3.0+)
(Check your motherboard’s BIOS to determine what mode the USB controller is configured for.)

@Soonts, no idea; there is no USB 2.1, and Googling it only finds Bluetooth (even when being even more restrictive). Are you actually seeing that on your system? If so, is it a third-party USB card or in your motherboard? If it’s the motherboard, what make/model is it?

@Soonts, hmm, that system has three USB2.0 ports and an optional USB3.0 port. I checked the specs and the manual and it says nothing that would explain it. Pages 18 and 21 of the manual clearly say it supports USB 2.0 and 1.1. Which device is showing0x0210? Is it on all ports of the device? A screenshot would help.

Disclaimer: Greg mentioned this utility in his answer, but as slm points out, his answer is a very sparse.
NirSoft has a free utility called USBDeview. This software will display lots of information about all USB devices currently and previously attached to the computer including the USB version:
Like most NirSoft utilities, it's a standalone executable that does not require installation. It also has command line options. It works extremely well and I have found it very useful. IMHO, it's easier to obtain than the MS USB View utility mentioned in the accepted answer. And USBDeview is less "cryptic" then USB View in the information it displays.

Also nice: for storage devices USBDeview has a quick integrated read/write test, justCtrl+tto see what it's actually operating at right now. What it doesn't have but I wish for is to also show the connection details, e.g. usb device itself is v3.0 but is connected to a v2.0 port.

I thought I would also add a reply because I found this tool which is based on the Microsoft USB View code but it adds a little bit to it:
http://www.uwe-sieber.de/usbtreeview_e.html
Moreover, unlike USB View this tool is freeware and you don't need to download a complete development kit to get it. I recommend.

If the device is using USB 1.0, windows will throw a message at you saying that there might be a problem with the device and that it is using a slower technology (in my experience).
Alternatively, you can write files to the drive and see how fast they get written/read. A USB 1.1 drive, while it has a theoretical speed of 12 MBit/S is usually far slower (<2 MBit). You will not see such speeds on a 2.0 drive unless there is something wrong with it or your computer.

Thanks for the suggestions, but this seems rather roundabout. There is no way to interrogate Windows directly and ask? For example, what if you have a dozen devices that are already plugged in? What about devices that are not writable (mice, keyboards, printers)?
– rlandster
Feb 10 '12 at 2:32

Few things. 1) most of the non-writable drives will probably be USB 1.1 as those devices generally don't need high bandwidth. 2) I don't think there is. The problem is that while you can get what the port is, knowing what protocol its using is buried somewhere (if at all visible, there is no reason why it should be)
– soandos
Feb 10 '12 at 2:42
@soandos: I'm not so sure about the first point. If a single USB 1.1 device is connected, all devices connected to the USB host controller are forced to downgrade to USB 1.1 speeds.
– surfasb
Feb 11 '12 at 2:13
@surfasb, soandos, you’re both close. Windows does indeed complain/warn when connecting a higher-speed device to a lower-speed USB port. And in my experience other devices do seem to get throttled to the USB spec of the device with the lowest support on the same hub, not the whole controller. As such, it will warn about a USB 2.0 device connected to a USB 2.0 port if there is a USB 1.1 device on the same hub (with a misleading message about the port being low-speed).
– Synetech

It gets more complicated than that. Some hubs will relegate full speed devices (1.1) to their own virtual bus. I just tell people to get rid of their old devices.

Also nice: for storage devices USBDeview has a quick integrated read/write test, just
Ctrl+t to see what it's actually operating at right now. What it doesn't have but I wish for is to also show the connection details, e.g. usb device itself is v3.0 but is connected to a v2.0 port.– matt wilkie

I thought I would also add a reply because I found this tool which is based on the Microsoft USB View code but it adds a little bit to it:
http://www.uwe-sieber.de/usbtreeview_e.html
Moreover, unlike USB View this tool is freeware and you don't need to download a complete development kit to get it. I recommend.

If the device is using USB 1.0, windows will throw a message at you saying that there might be a problem with the device and that it is using a slower technology (in my experience).
Alternatively, you can write files to the drive and see how fast they get written/read. A USB 1.1 drive, while it has a theoretical speed of 12 MBit/S is usually far slower (<2 MBit). You will not see such speeds on a 2.0 drive unless there is something wrong with it or your computer.

Thanks for the suggestions, but this seems rather roundabout. There is no way to interrogate Windows directly and ask? For example, what if you have a dozen devices that are already plugged in? What about devices that are not writable (mice, keyboards, printers)?

Few things. 1) most of the non-writable drives will probably be USB 1.1 as those devices generally don't need high bandwidth. 2) I don't think there is. The problem is that while you can get what the port is, knowing what protocol its using is buried somewhere (if at all visible, there is no reason why it should be)

@soandos: I'm not so sure about the first point. If a single USB 1.1 device is connected, all devices connected to the USB host controller are forced to downgrade to USB 1.1 speeds.

@surfasb, soandos, you’re both close. Windows does indeed complain/warn when connecting a higher-speed device to a lower-speed USB port. And in my experience other devices do seem to get throttled to the USB spec of the device with the lowest support on the same hub, not the whole controller. As such, it will warn about a USB 2.0 device connected to a USB 2.0 port if there is a USB 1.1 device on the same hub (with a misleading message about the port being low-speed).

It gets more complicated than that. Some hubs will relegate full speed devices (1.1) to their own virtual bus. I just tell people to get rid of their old devices.

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
Speed and USB version are not the same thing. USB 3.0 supports 4 different speeds, for instance: en.wikipedia.org/wiki/USB#Transmission_rates tr1.cbsistatic.com/hub/i/2009/12/22/…
