USB闪盘和thumb驱动器在写本文的时候还没有被全球支持服务完全支持。它们通常是即插即用设备，在插入USB端口的时候会被检测出，只需要最少的配置。

为了获取你的USB闪盘驱动器：

1. 缺省系统检测到设备。执行这个命令：

     tail -f /var/log/messages

2. 把闪盘插入一个USB插口。上面的命令会显示/var/log/messages的变化。下面是一个例子：

      Jun 27 12:18:09 localhost kernel: usb 1-5: new high speed USB device using ehci_hcd and address 9
      Jun 27 12:18:10 localhost kernel: Initializing USB Mass Storage driver...

      Jun 27 12:18:15 localhost kernel:     Additional sense: Not ready to ready change, medium may have changed
      Jun 27 12:18:15 localhost kernel: sda : READ CAPACITY failed.
      Jun 27 12:18:15 localhost kernel: sda : status=1, message=00, host=0, driver=08
      Jun 27 12:18:15 localhost kernel: sd: Current: sense key: Unit Attention
      Jun 27 12:18:15 localhost kernel:     Additional sense: Not ready to ready change, medium may have changed
      Jun 27 12:18:15 localhost kernel: sda: Write Protect is off
      Jun 27 12:18:15 localhost kernel: sda: assuming drive cache: write through
      Jun 27 12:18:15 localhost kernel: SCSI device sda: 512000 512-byte hdwr sectors (262 MB)

      Jun 27 12:18:15 localhost kernel: sda: assuming drive cache: write through
      Jun 27 12:18:15 localhost kernel:  sda: sda1
      Jun 27 12:18:15 localhost kernel: Attached scsi removable disk sda at scsi2, channel 0, id 0, lun 0
      Jun 27 12:18:15 localhost scsi.agent[3965]: disk at /devices/pci0000:00/0000:00:1d.7/usb1/1-5/1-5:1.0/host2/target2:0:0/2:0:0:0
      Jun 27 12:18:15 localhost fstab-sync[3989]: added mount point /media/usbdisk for /dev/sda1
      Jun 27 12:18:15 localhost fstab-sync[3992]: added mount point /media/usbdisk1 for /dev/sda

3. 执行lsmod命令。它会显示模块usb_storage和其他可能已经被加载的相关模块：

      Module                  Size  Used by
      usb_storage            74761  0
      sd_mod                 22977  0
      scsi_mod              136457  2 usb_storage,sd_mod

命令lsusb也会显示闪盘的ID:

      Bus 001 Device 009: ID 0ea0:2168 Ours Technology, Inc. Transcend JetFlash 2.0 / Astone USB Drive

从/var/log/messages可以看到，USB闪盘驱动器的文件系统已经被赋予设备名/dev/sda1。在红帽企业Linux4里，它应该被自动挂载到/media/usbdisk。在其他版本的红帽企业Linux里，这个挂载点不会被创建，但一个简单的mkdir就可以做这个事情。
