When you plug the BL-U90N into a USB port, you may see a notification that says "Device driver software was not successfully installed." If you open Device Manager (accessible by right-clicking the Start button), you might see the device listed under "Other Devices" with a yellow exclamation mark icon.

In the world of specialized hardware and industrial electronics, few things are as frustrating as plugging in a device only to have your computer fail to recognize it.
