How to detect removable disk is USB 2.0 or USB 3.0?

i suppose you could write a test file and measure the transfer speed.  Even the slowest usb3 device should hit 500MB/s, which would be faster than any USB2.0 device.

Hi

measure test  Spend too much time. I would like to get bcdUSB field .I don't know how to get bcdUSB ? like USBDeview.exe

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

 

#include <WinAPIFiles.au3>
$var2 = DriveGetDrive("REMOVABLE")

;Get Lable

Local $sLabel = DriveGetLabel($var2[1] & "\")
Local $sLabe2 = DriveGetLabel($var2[2] & "\")

;Get bcdUSB  ???

First you have to identify a USB 3 port.
Then you can do a speed test on the USB 3 port.

I had written a CMD script to measure transfer times.

Just copy the CMD file to the USB 3 device and click on it.

The script measures the transfer time of a 128 MB file and shows the result.

The result is also logged to the end of the CMD file.

I cant test because i dont have any USB devices around , but shouldn't  the info be stored somewhere here ?
