Cisco 9200L (C9200L-48T-4X) IOS Upgrade using USB - USB not detecting

[suneetmalhotra]

I have a weird situation where my 9200L box do not detect the file from USB. the logging shows that the usbdrive was removed but never shows it was inserted,

Has anyone tries specifically Cisco 9200 Catalyst boxes upgrade using USB ?

Also, what should be the file system of the USB drive ? (I blv it should be FAT32.

Basically usb-summary shows usb of 8GB, but not logs of detected usb. Rather, usb removed logs are seen

That will depend entirely on the brand (and size) of the USB flash drive. 

I use entirely Toshiba branded flash drive (8-, 16-, 32- and 64 Gb size) without fail. 

Recently, I found PNY-brand, v150w (64 Gb) and x760w (64 Gb), to be working and good.
