S: Manufacturer=Linux 3.8. lsusb is a utility for displaying information about USB buses in the system and the devices connected to them. In older systems, the deprecated usbfs filesystem provided similar information in /proc/bus/usb/devices.įor example, from a Beaglebone Black running Wheezy: $ sudo cat /sys/kernel/debug/usb/devices | grep -E "^(.*|)$" s : This option is used to display the only device specified by the bus and/or device number. Note that the /sys/kernel/debug/ path requires root privileges to access. sys/kernel/debug/usb/devices (or /proc/bus/usb/devices with usbfs)ĭetailed information on attached USB devices is available via the /sys/kernel/debug/usb/devices file. The discover package has a nice command too: $ discover -vendor-id -model-id usbĭiscover uses its own files : /lib/discover/usb-busclass.xml, /lib/discover/usb-device.xml, /lib/discover/usb-vendor.xml Output: This output displays all the USB controllers and the attached devices. You can also use the following command to view a much detailed information about each USB device lsusb -v. KDE's KInfo Center (in K Menu / System / KInfo Center Info Center, from package: kcontrol) has an information page on the "USB" cards. The lsusb lists information about all the USB controllers and the devices connected to them. Gnomes's System Information (Hardinfo in Menu Applications/System Tools, from package: hardinfo) has an information page on the "USB" cards. To get something slightly more verbose, but still readable, I use : # lsusb -v | grep -E '\/dev/null
