3750 running c3750e-universalk9-mz.152-4.E6.bin - no usbflash0 ?

[paulcahill]

Switch is a fresh boot, no config. IOS 15.2

I've tried 6 or 7 flash drives from 1GB up to 16GB all fat16 file systems with fresh formats. "sh usb device" sees the drive is plugged in. sh usbflash:/usbflash0:/usbflash1: all error out.

I have drives in my 3850 and Nexus 9ks, no problems. Am I missing something?

Thanks!

Could try fat32 or try format the USB from the switch when its connected see if it mounts that way

format usbflash0:

depending on usb vendor whether they work sometimes

If the USB thumb drive isn't recognize then try some more brand.
Cisco appliances are very "sensitive" to the the "type" of USB flash drives used.

i agree with poster above; try different brand of usb and lower capacity like 2-4 gig
