usbview (pkg) error

#1 Postby slopoke » Sat Dec 10, 2011 9:45 pm

I just installed a package (usbview). It opens but gives the following error (as user and root).

USBView Error
Can not open the file /proc/bus/usb/devices.

Verify that you have USB compiled into your Kernel, have the USB core modules loaded, and have the usbdevfs filessystem mounted.

Isn't that supposed to be done at installation of the OS?

MEPIS doesn't automatically mount the usbdevfs filesystem, and its name was shortened a couple years back to usbfs. The development of udev has made it unnecessary for most purposes, but it's still in the kernel if you want it.
You can mount it manually with this (root user) command:

Code: Select all

mount -t usbfs none /proc/bus/usb
or add this line to /etc/fstab afer the proc entry

Code: Select all

none /proc/bus/usb usbfs defaults 0 0
if you want it mounted automatically on each boot.

Once the usbfs is mounted, usbview works as expected.
