CentOS 2.6.19.1: mounting /proc/bus/usb already mounted or busy
 

I'm trying to communicate with an external device connected through my usb. There is a script that came with the device that sets it up, only it fails before it can assign the device any IP settings.

The message returned that leads me to this: "Cannot determine address for "localhost" "

This tells me that the script cannot communicate properly with the device. So I must have a problem with the usb driver.

I know the usb cable needs FTDI chip drivers, I was told Fedora & CentOS already have them installed, but I downloaded them anyway. I followed the guide up to mounting the usbfs when I get the returned message "mount: none already mounted or /proc/bus/usb busy". None is what was used in the installation guide. I used the command

lsof | grep '/proc/bus/usb' | grep -v grep

to see any locks but it returned nothing. If the mounting isn't the problem then I need to contact the device manufacturer. I don't want to just yet because I feel there is a simple answer I'm unaware of.

Thanks,
Chris

No version of Centos runs a .19 kernel. Centos5.X has and will for its entire life cycle run a 2.6.18 based kernel (2.6.18-128.2.1 is current). As you are running a custom kernel it is going to be difficult to even guess what you have going on. The reason RHEL/Centos stick with one specific kernel to base any on release(4.x,5.x, etc) is to maximize compatibility. RHEL/Centos does back patch their kernels to make them the equivalent (security and hardware wise) of more current kernels. In reality RHEL's .18-128 is probably much closer to a .26 kernel than it is to a vanilla .18 kernel.
