Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

There used to be lots of info on usb devices, coming form /proc/bus/usb/devices.

Then this was no longer auto mounted, so you had to mount it yourself (usbdevfs it was called, or something)

Now, in 11.04, even that doesn't work. How can I get some info on my device now?

lsusb shows this:

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 004: ID 0bda:0138 Realtek Semiconductor Corp. 
Bus 001 Device 003: ID 064e:c218 Suyin Corp.  
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

What more do you need to know?

If you need more there is usbview on sourceforge: USBView is a GTK program that displays the topography of the devices that are plugged into the USB bus on a Linux machine. It also displays information on each of the devices. This can be useful to determine if a device is working properly or not.

did not try usbview in 11.04 btw

/proc is becoming deprecated, /sys/bus/usb/devices is what you are looking for. A program to query for USB devices is lsusb.
