NAME
dump_usbdev − Dumps connected USB devices information
SYNTAX
dump_usbdev [−Vvds] [file]
DESCRIPTION
The utility dump_usbdev aids you in writing usbmgr.conf. After usbmgr has been started, running dump_usbdev will dump infomation about all attached devices in a format suitable for usbmgr.conf.
If you connect USB devices to your USB HUB, you’ll see a line like the following:
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
class 0x9 subclass 0x0 protocol 0x0 module
<module_name>
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
This line will help you writing your
/etc/usbmgr/usbmgr.conf configuration file.
OPTIONS
|
−V |
Prints version. It DOES NOT exit. | ||
|
−v |
Verbose mode. | ||
|
−d |
Debug mode. Prints device data details. | ||
|
−s |
Print simply the device numbers, not the entire configuration file text. | ||
|
file |
Specify alternate file to read data from, instead of the default /proc/bus/usb/001/*. If it’s not an absolute path, take as /proc/bugs/usb/001/file. The file format is a series of register of type usb_device_descriptor. |
FILES
/proc/bus/usb/001/*
ENVIRONMENT VARIABLES
None.
EXAMPLES
To run this program the standard way type:
dump_usbdev
If you want to debug its output, you can create an appropriate file as myfile and call it:
dump_usdev /path/to/myfile
In the following output:
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
class 0x9 subclass 0x0 protocol 0x0 module
<module_name>
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
"class 0x9" means USB HUB. If no USB devices are connected, only the root HUB will appear. Modifying "<module_name>" would complete the configuration for this device (HUB). In the case of a HUB, you should change "module_name" to "none" because the HUB driver is included in usbcore.
After a USB mouse has been connected to the HUB, running dump_usbdev will give you the following:
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
class 0x9 subclass 0x0 protocol 0x0 module
<module_name>
vendor 0x56e product 0x4 module <module_name>
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
The 2nd line is new. This is the infomation about the USB mouse. The USB mouse requires the "hid" and "mousedev" drivers. So, "<module>" should be changed to "hid , mousedev".
So the complete usbmgr.conf would look like this:
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
class 0x9 subclass 0x0 protocol 0x0 module none
vendor 0x56e product 0x4 module hid , mousedev
−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
You should copy this into /etc/usbmgr/usbmgr.conf, and then run update_usbdb to create the configuration data.
