/sbin/rmmod usb-storage - najlepsie cez sudo ak nie si root

TiMEoS: dmesg ti povie ake tam mas particie, napriklad moj usb key:
Kód:
usb 1-1: new full speed USB device using address 7
Initializing USB Mass Storage driver...
scsi0 : SCSI emulation for USB Mass Storage devices
  Vendor: Apacer    Model: HandyDrive        Rev: 1.05
  Type:   Direct-Access                      ANSI SCSI revision: 02
SCSI device sda: 128000 512-byte hdwr sectors (66 MB)
sda: Write Protect is off
sda: assuming drive cache: write through
sda: sda1

montujem sda1

alebo fdisk -l vypise vsetky dostupne particie na diskoch (ako root)
