USB storage are USB harddisks and USB memory sticks.
Find them in the system
To find out if a USB stick works, open a console and enter
dmesg | tail -f
and insert the stick. You will find some lines like
[44950.907137] usb 2-1.5: new high speed USB device using ehci_hcd and address 4 [44950.995677] usb 2-1.5: New USB device found, idVendor=13fe, idProduct=3123 [44950.995682] usb 2-1.5: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [44950.995686] usb 2-1.5: Product: STORE N GO [44950.995689] usb 2-1.5: Manufacturer: Verbatim [44950.995691] usb 2-1.5: SerialNumber: 078B06E70173 [44950.996463] scsi7 : usb-storage 2-1.5:1.0 [44952.030933] scsi 7:0:0:0: Direct-Access Verbatim STORE N GO 5.00 PQ: 0 ANSI: 0 CCS [44952.031382] sd 7:0:0:0: Attached scsi generic sg8 type 0 [44952.465358] sd 7:0:0:0: [sdh] 31735808 512-byte logical blocks: (16.2 GB/15.1 GiB) [44952.466109] sd 7:0:0:0: [sdh] Write Protect is off [44952.466114] sd 7:0:0:0: [sdh] Mode Sense: 23 00 00 00 [44952.466118] sd 7:0:0:0: [sdh] Assuming drive cache: write through [44952.470271] sd 7:0:0:0: [sdh] Assuming drive cache: write through [44952.470276] sdh: sdh1 [44952.502054] sd 7:0:0:0: [sdh] Assuming drive cache: write through [44952.502060] sd 7:0:0:0: [sdh] Attached SCSI removable disk
The bold line tells you the stick has been attached as device /dev/sdh and has one partition, /dev/sdh1.
To get an overview of all inserted USB devices, use
hwinfo --usb
To get an overview of all storage devices, use
hwinfo --block
