BASH根據PCI ID找到USB驅動器連接到哪個端口

Question

基本上我需要驗證USB驅動器是否連接到某個USB端口。我有以下幾點：

USB驅動器實際上被標記：

• 白，綠，紅

我有同樣物理標記3個USB端口：

• 白，綠色，紅色

使用BLKID我可以從驅動器接收信息，如

BLKID Example 
/dec/sdb1: SEC_TYPE="msdos" LABEL="WHTIE" UUID="78FE-870D" TYPE="vfat" 

因此，我只知道標籤知道很多關於驅動器本身的知識。現在我使用LSPCI我可以得到關於USB端口的信息，因爲我知道每個橋的ID。例如：

LSPCI Example 
0a.00.0 USB Controller: some info 4d88 

因此，最後一部分4d88是PCI ID。

所以我知道的PCI ID每個端口的，需要對其進行匹配的USB驅動器本身，如：

• 4d88 =白色
• 4dC0 =綠色
• 4d84 = RED

我不知道如何匹配/檢查這種關係。任何幫助將不勝感激。

答案：感謝您的幫助。

由於lspci的，的lsusb，BLKID的要求轉儲。

Answer 1

這是我會怎麼做我的系統上：

第1步：查找設備節點：

# blkid | grep MyDisk 
/dev/sdj1: LABEL="MyDisk-0" UUID="4876-5945" TYPE="vfat" 

的設備節點/dev/sdj1。

第2步：/sys是你的朋友：

# ll /sys/block/sdj 
lrwxrwxrwx 1 root root 0 Feb 3 00:40 /sys/block/sdj -> ../devices/pci0000:00/0000:00:1a.7/usb1/1-2/1-2:1.0/host15/target15:0:0/15:0:0:0/block/sdj/ 

上面的符號鏈接目標包含有用信息的很多，包括通過SCSI從你的閃存驅動器的路徑回PCI橋和USB子系統。

步驟3：上述從鏈接目標隔離（在這種情況下00:1a.7）PCI總線ID和lspci檢查：

# lspci | grep 00:1a.7 
00:1a.7 USB Controller: Intel Corporation 82801JI (ICH10 Family) USB2 EHCI Controller #2 

如有疑問，檢查lspci輸出視覺...

這裏是自動進行的凝固酶原極爲原油和極其脆弱的方式SS之上：

blkid | 
    grep Label | 
    cut -d : -f 1 | 
    sed 's|[0-9]*$||; s|^/dev/|/sys/block/|' | 
    xargs readlink | 
    cut -d/-f 4 | 
    xargs -n 1 lspci -s 

注：此作品在我的系統上，但它絕不是安全的（或推薦）：

1. 如果一個內核更新改變/sys佈局這將打破文件系統。

2. 如果您有不同的設備佈局，它可能會中斷，但您應該可以爲此進行調整。
