Catalyst 9300 cannot copy file from usb. usbflash0: not found.

[Mogwai]

Running version 17.07.01 & looking to update it. I've formatted the USB to FAT32 & copied the new IOS version to it as a .bin file. When I insert the USB to the 9300 switch, the switch doesn't seem to see it. 

Thoughts?

Switch#dir usflash0:
           ^
% Invalid input detected at '^' marker.

Switch(config)#exit
Switch#dir ?
/all List all files
/recursive List files recursively
all-filesystems List files on all filesystems

@Mogwai you have a typo and are missing the b, in usb. Try running show file system, you should see the usb then.

Sorry, I had typed the command properly, the first few times, but figures when I went to recreate it for the case I typo'd it. That being said the USB is still not being recognized.

You could try FAT16, i saw some other posts which said this was ok. Hope you have not hit this https://bst.cisco.com/quickview/bug/CSCvk49306 - i cannot see your version on here tho...

  - @bigevilbeard     For some reason your bug url gives a 403 error for me ; this one seems to work

Thanks pals! I might have shared the login page.

I'll try FAT16 & see what happens, I did see that bug, but the current version on the switch is 17.07.01, which that bug shouldn't be affecting, but after seeing that report i did reboot the switch just to see and the USB still didn't show.

FAT16 worked.  Thanks
