VirtualBox USB can not be installed on Win 7 64 Bit Host
Posted: 28. Oct 2009, 19:12
Hello everybody,
I´m running VirtualBox 3.0.8 (same problem with 3.0.6) on a Windows 7 Ultimate 64 it host (German edition!). Just upgraded from Vista Ultimate 64 bit (German edition too) where all was ok. Hardware is a Core 2 Quad Intel CPU (Q8300) with 2,53 GHz and 8 GB RAM. I´m using a guest with Win 7 RC 32 Bit (before someone asks: I don´t have a 64 Bit RC!). The guest has 2 GB RAM. At first (and still with VBox 3.0.6, which I had been running under Vista 64 Bit, due to frequent bluescreens in the guest with VBox 3.0. everything seemed ok after upgrading the host to Win 7. The VM was starting normal and there were no warnings, etc. When I experienced some bad performance of USB-Gear in the guest (i.e. a Philips Speechmike I, LFH 6274) I tried upgrading VBox to 3.0.8. While the VM still starts and runs normally, all USB support for the VM is gone. Changing back to VBox 3.0.6 doesn´t help. After installing VBox and starting the VM, the host tries to install "VirtualBox USB" driver but is not succesfull. The host displays a message saying that the driversoftware was not installed, added by "VirtualBox USB Device removed". Remember: I´m using a German Windows so the messagetext is my translation; the exact message may differ on nongerman editions of Windows, but the meaning ist translated correctly.
Uninstalling and reinstalling VBox does not help (either with 3.0.6 or 3.0.8; I tried it repeatedly). Uninstalling "VirtualBox USB" from the device manager does not help either. Originally "VirtualBox USB" was not even shown in the device manager, even with "show hidden devices" selected, since the host sees it as a disconnected device. I had to add the system variable devmgr_show_nonpresent_devices=1, before it was shown as a greyed out device, which then could be deleted. Needless to say, that I did boot my computer after each attempt to install / uninstall VBox, or USB-Drivers.
Has anybody a solution how to get the "VirtualBox USB" driver installed and working on Win 7 Ultimate 64 bit? Any help is greatly appreciated!
Thanks in advance.
