I've been using the 3.16 line of code on our ISR's and used the USB port to upgrade code by plugging in a thumb drive.
I've recently tried the new 16.3 and 16.6 versions of IOS and found I can't use a thumb drive anymore. I don't remember reading this in the release notes.
Does anyone know if Cisco removed the ability to mount a USB drive in the newer versions of code?
Here's the output of 16.6.2. No usb0:
Router#dir ? /all List all files /recursive List files recursively all-filesystems List files on all filesystems bootflash: Directory or file name cns: Directory or file name flash: Directory or file name null: Directory or file name nvram: Directory or file name system: Directory or file name tar: Directory or file name tmpsys: Directory or file name webui: Directory or file name | Output modifiers <cr> Router#

You're right. It see's the USB but I can't access it.

It's a Dell 8GB USB stick. If I do a "dir /all" it only shows me bootflash:. No other drives.
I should also mention, if I boot into 3.16, the same router and USB stick work just fine. Boot back into 16.6.2 and I can't see the USB anymore.

Look for one of these: Samsung Bar 16 Gb.

I don't have one of those.
Is there a list of "Cisco Approved" USB sticks? Why should that matter? This USB stick worked before the code upgrade.

Correct. The product are made by monks who's never uttered a single word for the last 6 years, hence the cost.

I just had the same problem. The solution is to get a slightly better quality stick.
The $5 16GB plastic stick was a no go on the latest software but a thin metal $20-ish Kinston 32GB USB3 worked just fine.
