通过lsusb返回idVendor、idProduct和端点

Question

我只想归还一些我可爱的打印机的数据。(名称始终包含STMicroelectronics printer

我可以用lsusb命令打印出所有插入的USB设备。这将给我(第一行显然是打印机)：

Bus 001 Device 004: ID 0483:5743 STMicroelectronics printer-80
Bus 001 Device 003: ID 0424:ec00 Microchip Technology, Inc. (formerly SMSC) SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Microchip Technology, Inc. (formerly SMSC) SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub`

我现在可以通过lsusb -vvv -d 0483:5743找到设备的详细信息，它返回：

现在..。我如何才能通过bash返回这些数据：

idVendor (0x0483)
idProduct (0x5743)
endpointOUT (0x01)
endpointIN (0x81)

一定有一些grep/regex魔法，我就是无法掌握。

谢谢您提前提供帮助！

正在寻找解决方案，以使用regex提取包含打印机描述的行。

Answer 1

使用GNU sed

$ sed -En 's/[ \t]*b?(id[vp][^ \t]*|endpoint)(address)?[ \t]+([^ \t]*).* (out|in)?.*/\l\1\4 (\3)/Ip' <(lsusb | awk '$0 ~ /STMicroelectronics printer-80/{print $6}' | xargs -I % sh -c "lsusb -vvv -d %")
idVendor (0x0483)
idProduct (0x5743)
endpointOUT (0x01)
endpointIN (0x81)

Answer 2

建议使用以下awk脚本：

awk '/idVendor/||/idProduct/{printf("%s (%s)\n", $1,$2)}/bEndpointAddress/{printf("endpoint%s (%s)\n", $NF, $2)}' <<<$(lsusb -vvv -d 0483:5743)
