How do I find the device node file for a USB device in Linux?

Question

I've bought an X10 Home Automation USB interface: the CM15.

This is the information lsusb gives:

skerit@KIP-DU-SKER:~$ lsusb
Bus 008 Device 002: ID 0bc7:0001 X10 Wireless Technology, Inc. ActiveHome (ACPI-compliant)

But this tells me nothing about where the device file is! How can I find that, or create one myself?

Answer 1

Device nodes are created by udev automatically. If it's a storage device, sudo lsblk -f or sudo blkid should list it. Serial devices are always ttyUSBnum. For everything else, check the system log in dmesg.
