Hi,
I only get a segmentation fault with the CC_demo program when running as root.
I installed /proc/bus/usb/001 by using this manual:
https://help.ubuntu.com/community/VirtualBox/USB:
| Code: | #
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs usbfs-obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb |
For the software I used xxusb_3.14.
Any ideas?
Cheers, Peter
Edit: Solved.
The module didn't show up in the usb device list using lsusb.
After a reboot and one initialization using windows (not sure if needed, it was a check if it shows up there) the device is responding for the root account.
Doh! |

Hi Peter,
which version of Virtualbox are you using? I was trying to run the VM-USB in an Ubuntu VM on a VISTA platform. However Virtualbox version 2 did not support all USB calls. The USB memory stick works but not VM-USB.
Any details about your configuration could be helpful.
Thanks
Andreas

Hi Andreas,
sorry, I am not using Virtualbox. I was just referring to this guide for the code I used for setting up the devices (in Intrepid these lines in /etc/init.d/mountdevsubfs.sh were removed).
