14124	USB EHCI 2.0 Controller issue on Windows 7 Professional as guest OS: the VM aborts while using the USB stick	Nicholas		"Kind Virtualbox Support and Development team,

 I'm reporting an issue with the USB 2.0 EHCI module issue on Windows 7 Professional as guest OS and Debian Wheezy 7.8 as host OS: the VM aborts while using the USB stick Verbatim Store'n'Go 4G.

 It seems that the problem appears while writing on the device, small files, such as text file or directories creation, are performed without problem, but when there is a directory copy with files bigger than 1MB the VM aborts.

 The same happens with Windows XP as guest OS, but in this case it is
possible to disable the 2.0 USB controller and the all works smoothly with the 1.0 USB emulation.

 The extension pack 4.3.28_r100309 and the same version guest additions are properly installed and the user is inserted in vboxusers group as described in the documentation.

 Please at your earliest convenience check the module and let me know.

Thank You All in Advance.
