This question seems to be all over google, but the answers all point to using System Profiler. That's nice, but with System Profiler all you get is something that looks like this:
DasKeyboard: Product ID: 0x1919 Vendor ID: 0x04d9 (Holtek Semiconductor, Inc.) Version: 1.06 Speed: Up to 1.5 Mb/sec Location ID: 0x1d114000 / 11 Current Available (mA): 500 Current Required (mA): 100 USB2.0 Hub: Product ID: 0x0608 Vendor ID: 0x05e3 (Genesys Logic, Inc.) Version: 32.98 Speed: Up to 480 Mb/sec Location ID: 0x1d113000 / 10 Current Available (mA): 500 Current Required (mA): 100 Microsoft Basic Optical Mouse v2.0 : Product ID: 0x00cb Vendor ID: 0x045e (Microsoft Corporation) Version: 1.99 Speed: Up to 1.5 Mb/sec Manufacturer: Microsoft Location ID: 0x1d113200 / 12 Current Available (mA): 500 Current Required (mA): 100That's great if all you want are the contents of a bunch of device descriptors, but lsusb gives you so much more - information on interfaces and endpoints, interface associations, composite devices... where can you find this information in OS X? There must be a tool that does this?

I got tired of forgetting the system_profiler SPUSBDataType syntax, so I made an lsusb alternative. You can find it here , or install it with homebrew:
brew install lsusbI typically run this command to list USB devices on Mac OS X, along with details about them:
ioreg -p IOUSB -l -w 0Homebrew users: you can get lsusb by installing usbutils formula from my tap:
brew install mikhailai/misc/usbutilsIt installs the REAL lsusb based on Linux sources (version 007).
In mac osx , you can use the following command:
system_profiler SPUSBDataTypeIf you are a user of MacPorts, you may simply install usbutils
sudo port install usbutilsIf you are not, this might be a good opportunity to install it, it has ports for several other useful linux tools.
3system_profiler SPUSBDataTypeit your need command on macos
How about ioreg? The output's much more detailed than the profiler, but it's a bit dense.
Source:
1At least on 10.10.5, system_profiler SPUSBDataType output is NOT
dynamically updated when a new USB device gets plugged in,
while ioreg -p IOUSB -l -w 0 does.
On Mac OS X, the Xcode developer suite includes the USB Proper.app application. This is found in /Developer/Applications/Utilities/. USB Prober will allow you to examine the device and interface descriptors.
