Error with USB subsystem

[HuaMin]

Hi,
After I've set up relevant extension pack for my VBox 4.2.6, I am still getting the attached problem which was posted in other thread. Please advise. Thanks.

Post a log file for the VM. The VM log file is called "VBox.log", and can be found in the "Logs" subfolder of your VM folder.

Your FIX is in post 53715.

Sorry but I'm new and the system limits what and where I can post.

Good Luck
