sudo lsusb will tell you what usb devices Linux detects. Whether a usb storage device mounts, or is detected, are separate issues. sudo lsusb -v will give verbose output, possibly more information than you want if the OS truly doesn't recognize the device.

here is dmesg output of when i just pluged a memory stick in my computer:
