linux下用wireshark抓usb

首先安装

usbmon 一般都安装了
Ubuntu 商店直接安装wireshark

sudo add-apt-repository universe
sudo apt install wireshark

usbmon 与wireshark 关联

如果不是所有用户使用，需要加sudo

addgroup usbmon

gpasswd -a $USER usbmon

echo 'SUBSYSTEM=="usbmon", GROUP="usbmon", MODE="640"' > /etc/udev/rules.d/99-usbmon.rules

问题

he capture session could not be initiated on capture device “usbmon1” (You don’t have permission to capture on that device).
