Determine owner/group of a USB device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Many people across the internet offer advice about how to set
owner/group of a USB device: Add a udev node like the following:
SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="04b4",
ATTR{idProduct}="8613", GROUP="usb", MODE="0660"

My question:

How do I view the current owner and group of a USB device?

Answer:

a) ls -l /dev.  Hint: grep for the vendor id in hex

b) this is impossible, that is why you are having such a hard time
finding the answer

c) lsusb -v

d) why don't you write your own usb subsystem if you don't like this
one/go to hell

e) [your idea here]

Thank you,

Chris
