Can't map removable USB storage by iDRAC Virtual Console c - Virtual Medai

I connect to iDRAC - Virtual Console, open Virtual Media , lanch "Map External Device."

System run Java script and show Map Remove Disk screen.

But can't find my USB storage at Select Drive item.

I 'd try different USB storage (FAT32/exFAT / 16G 128G) and different browser (Cheome / Edge / Firefox).

But all fail.
