5.1. Help, I have a USB webcam and don't know exactly what model it is and/or who the manufacturer is. What do I do?
Use lsusb ; it can give you an idea of what other USB devices are available on your system, too:
$ lsusb
Bus 007 Device 001: ID 0000:0000
Bus 006 Device 001: ID 0000:0000
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 003: ID 0545:8080 Xirlink, Inc. IBM C-It WebCam
Bus 003 Device 002: ID 046d:0840 Logitech, Inc. QuickCam Express
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 003: ID 051d:0002 American Power Conversion Back-UPS Pro 500/1000/1500
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
The numbers after 'ID' are the Vendor and Product numbers, respectively. They can then be looked up in the Linux USB ID catalog .
If lsusb is not available to you, and you have support for /proc filesystem support and USB-filesystem support, issue the following at the command line:
$ cat /proc/bus/usb/devices
You should receive output including (but not necessarily limited to) the following:
T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=3 Spd=12 MxCh=0
D: Ver= 1.01 Cls=ff(vend.) Sub=ff Prot=ff MxPS=8 #Cfgs=1
P: Vendor=0545 ProdID=8080 Rev= 3.0a
S: Product=USB IMAGING DEVICE
The line beginning "T:" is the USB bus the device is attached to. The "P:" indicates (obviously) the vendor and product ID, which are catalogued at the linux USB Project homepage .
