Unable to detect Imation flash drive but able to see it in device manager

Hi Nithin,

Thank you for posting your question in Microsoft Community.

This issue can be caused if any of the following situations exist:

•The currently loaded USB driver has become unstable or corrupt

•Your PC requires an update for issues that may conflict with a USB device and Windows

•Windows may be missing other important updates hardware or software issues

•Your USB controllers may have become unstable or corrupt

•Your PC motherboard may need updated drivers

I would really appreciate if you could answer the following questions:

1. Which operating system is installed on your computer?

Which Windows operating system am I running?

Method 3:

You may also see in Device Manager that the device shows up as an “Unknown Device”.

Simply UNPLUG YOUR COMPUTER FROM THE POWER SUPPLY. Note that this does not mean just turning off your computer because modern computers don’t really turn off when you press the power button as the motherboard still gets power.

First to explain, the motherboard is where all of hardware of the computer is connected to, including the USB ports. Sometimes the motherboard needs to be “rebooted” also because something can go wrong, i.e. all your USB ports suddenly stop working. The small microprocessor on the motherboard will reload the drivers and your USB ports should be back to recognizing all devices!

So first turn off your computer using Shut Down or pressing the power button and then UNPLUG it from the wall outlet. Let it sit for about a minute and then plug it back in and check.
