Lsusb output full#
You'll also get the full system path to the device, namely /sys/devices/pci0000:00/0000:00:14.0/usb3/3-3. The source would be the next logical step.-Tim Roberts, Providenza & Boekelheide, Inc. Does anyone here have any idea what I could be doing wrong Nothing obvious here. If desired, I can also supply my program source. Integrated Rate Matching Hub Bus 001 Device 003: ID 0bda:0139 Realtek Semiconductor Corp. Ive attached a full debug log and lsusb output. Integrated Rate Matching Hub Bus 002 Device 002: ID 8087:0024 Intel Corp. idVendor=067b, idProduct=2303), when ( Apr 19 11:20:05) and what device node the device ( ttyUSB0) can be accessed through. lsusb output : Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp. In this log excerpt you will see the VendorID and ProductID of a Serial-on-USB controller, which uses a chip, a PL2303 ( pl2303), from a company named " Prolific Technology Inc.".īy looking at these lines you will know what device you plugged in (e.g. However - assuming you don't know how plug and play works on USB - the "why" lsusb is that every removable device, that you plug into the USB connector, signals to the system (amongst other information) identifiers for the vendor and product, respectively idVendor and idProduct, both of which you can see in lsusb output.Īnother way is to check the system log, which provides more verbose information: Apr 19 11:20:05 my_machine kernel: usb 3-3: new full-speed USB device number 72 using xhci_hcdĪpr 19 11:20:05 my_machine kernel: usb 3-3: New USB device found, idVendor=067b, idProduct=2303Īpr 19 11:20:05 my_machine kernel: usb 3-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0Īpr 19 11:20:05 my_machine kernel: usb 3-3: Product: USB-Serial Controller DĪpr 19 11:20:05 my_machine kernel: usb 3-3: Manufacturer: Prolific Technology Inc.Īpr 19 11:20:05 my_machine kernel: pl2303 3-3:1.0: pl2303 converter detectedĪpr 19 11:20:05 my_machine kernel: usb 3-3: pl2303 converter now attached to ttyUSB0Īpr 19 11:20:05 my_machine mtp-probe: checking bus 3, device 72: "/sys/devices/pci0000:00/0000:00:14.0/usb3/3-3"
As hinted, you may find information using lsusb.
