34 | If you say Y here (and to "/proc file system support" in the "File | ||
35 | systems" section, above), you will get a file /proc/bus/usb/devices | ||
36 | which lists the devices currently connected to your USB bus or | ||
37 | busses, and for every connected device a file named | ||
38 | "/proc/bus/usb/xxx/yyy", where xxx is the bus number and yyy the | ||
39 | device number; the latter files can be used by user space programs | ||
40 | to talk directly to the device. These files are "virtual", meaning | ||
41 | they are generated on the fly and not stored on the hard drive. | ||
42 | |||
43 | You may need to mount the usbfs file system to see the files, use | ||
44 | mount -t usbfs none /proc/bus/usb | ||
45 | |||
46 | For the format of the various /proc/bus/usb/ files, please read | ||
47 | <file:Documentation/usb/proc_usb_info.txt>. | ||
48 | |||
49 | Modern Linux systems do not use this. | ||
50 | |||
51 | Usbfs entries are files and not character devices; usbfs can't | ||
52 | handle Access Control Lists (ACL) which are the default way to | ||
53 | grant access to USB devices for untrusted users of a desktop | ||
54 | system. | ||
55 | |||
56 | The usbfs functionality is replaced by real device-nodes managed by | ||
57 | udev. These nodes lived in /dev/bus/usb and are used by libusb. | ||
