一）Linux下一个简单命令检测你的电脑上是否有USB 3.0接口：
lsusb -tv # 列出所有USB设备,通常情况下USB3.0接口是蓝色的，所以大家只要看到USB接口是蓝色的即可确认该接口是USB 3.0接口。
二）在Ubuntu中折腾了好几天终于解决了usb3.0不能开启：

1.lsusb命令的RPM包yum安装：
rpm -qf /usr/bin/lsusb
usbutils-007-5.el7.x86_64
[root@localhost ~]# lsusb
lsusb lsusb.py
[root@localhost ~]# lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. Hub
Bus 002 Device 003: ID 2c7c:0125
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
2.如何得到硬盘的信息？
1，用fdisk -l 可以得到系统中已安装的硬盘列表及分区情况
[root@localhost lhd]# fdisk -l
Disk /dev/sda: 40.0 GB, 40060403712 bytes
255 heads, 63 sectors/track, 4870 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xf0b1ebb0
Device Boot Start End Blocks Id System
/dev/sda1 * 1 1275 10241406 c W95 FAT32 (LBA)
/dev/sda2 1276 4870 28876837+ f W95 Ext'd (LBA)
/dev/sda5 1276 2550 10241406 b W95 FAT32
/dev/sda6 2551 2575 200781 83 Linux
/dev/sda7 2576 4870 18434556 8e Linux LVM
2，如何得到硬盘的品牌及相关信息
1，smartctl -i /dev/sda
说明： smartctl是用来控制和监视 smart disk的程序
-i 参数用来显示设备的相关信息
例：
[root@localhost lhd]# smartctl -i /dev/sda
