Hey guys we have a new 4510 that we were upgrading the IOS for and it has a USB port on each supervisor card. The image we were upgrading to was cat4500es8-universalk9.SPA.03.06.03.E.152-2.E3.bin
The USB was formatted to FAT which is what is recommended and after putting the IOS on the flash drive, we attempted to load the image to the switch and the switch couldn't detect the USB drive at all.
We did all the various show commands, tried different USB sticks (each one we tried we formatted just like the 1st one) and it still wouldn't detect it.
It kept saying something similar to "No USB drive present" or "USB0 does not exist"
The USB stick was getting power as we saw the red light on the stick itself stay "solid red" but the switch could not see it or read any files on the flash drive. I am pretty sure if it was working properly as soon as i insert the USB stick the switch CLI would say "USBFlash1 has been inserted" or something like that.
Has anyone experienced something like this? Could it be a license issue?
