Inquiry:How to recognize the assigned device for attached usb memory?

Why don't you just plug in the drive and then tail the dmesg. Like this

Code:

dmesg | tail

You seem to be missing the required drivers. Please run the following
command to add the usb_storage module into the running kernel:

Code:

modprobe usb_storage

Now try inserting your usb stick again, and then look at the output of dmesg.

HTH,

Evo2.

Please find attached the dmesg output after issuing the "modprobe usb_storage" .

Did you reinsert the USB thumb driver after runing modprobe and before running dmesg?
