I have an old Thinkpad R32 2658 and I want to use dfu-util. The reference documentation starts with the following description:

To run dfu-util, you need to have /proc/bus/usb mounted and working. The terminal command "ls /proc/bus/usb" should return something similar to, "001 002 003 004 005 devices", it shouldn't be empty. If it is empty, use this command: sudo mount -t usbfs usbfs /proc/bus/usb

The problem is: I don't have /proc/bus/usb at all. In /proc/bus there are only input and pci sub-directories. But I do have USB ports on my old notebook and my USB keys work well.

What can I do?

Can you please take a look at this forum entry and report if this works for you? Please note, the author of the answer states that this is not a long-term solution. –  bender Jan 17 '13 at 22:29
    
Find a tool that supports sysfs instead. –  Ignacio Vazquez-Abrams Jan 17 '13 at 22:33
    
@bender: thanks for the link! This is a workaround that works for me as well :) I hope it won't cause any further problems when using dfu-util, but for now it looks good, thanks again! –  Wolfson Jan 19 '13 at 11:38
    
Could you then please write an official answer to your own question for the sake of documentation? And after a day you even will be able to accept your own answer. –  bender Jan 19 '13 at 14:48
    
@bender: ok, sorry, I did not know how that works, that was my first question here ;) –  Wolfson Jan 19 '13 at 18:52

Not strictly a solution but a workaround that worked for the author of the question is available in this forum entry.

Please note, the author of the answer above states that this is not a long-term solution.

In 12.04 (and perhaps before), /usb/bin/usb-devices is a script that provides similar info.

Not in 13.04, doubtful in later releases. –  Braiam Oct 29 '13 at 19:06
