USB Port Not Working - 1941

Level 1
Level 1

I have a new 1941 that the USB data ports are not appearing.

It is running 15.4

The following results are with flash drives plugged into the USB0 and USB1 slots.

In doing a DIR, get the following listed:

dir ?
/all List all files
/recursive List files recursively
all-filesystems List files on all filesystems
archive: Directory or file name
cns: Directory or file name
flash0: Directory or file name
flash1: Directory or file name
flash: Directory or file name
null: Directory or file name
nvram: Directory or file name

tar: Directory or file name
tmpsys: Directory or file name
xmodem: Directory or file name
ymodem: Directory or file name

While not having the USB running is minor, I would like to be able to get everything working properly.

Thoughts or suggestions?

Thank you

Cisco routers are particularly "sensitive" to what type/brand of USB thumb drive used.  The thumb drive may be "supported" in Cisco switches but it is no guarantee the same thumb drive will work with routers. 

Newer IOS has the ability to disable the USB port.

Hello,

 

according to the post below,it is a software bug, and you need to down or upgrade.

I want to know the exact firmware version. 

What are you plugging in, a USB thumb drive or a USB HDD?

A variety of USB Flash Drives. 4GB, 8GB, and 16GB.

I had formatted one of the 16GB drives to have a 4GB FAT16 partition, based on what I had read on another post.

the flash drives work fine in a G350 switch.
