Here now my conclusion of what happened.
Yesterday i installed the USB 3 Drivers for Windows 7 mentioned in step 6 of the tutorial from socratis. The thing that I did not do was rebooting my Notebook. So new day, new reboot of the host and guest system and it works. Now i can plug in my usb devices and when the drivers are found it should work. The final tests have still to come, but what i saw until know is really good.scottgus1 wrote:Looks like you found and used Socratis' USB tutorial. Good work, and good thorough info in your post!
If I read your guest log right, you're using the USB 3 xHCI device. All of your guests, including the logged one posted, are Windows 7. Did you install the USB 3 drivers for Windows 7 mentioned in step 6 of the tutorial?
For other people who might have a similar problem just try to install the drivers mentionned above and don't forget to reboot everything.
The Errormessages that i got before i installed and rebooted the notebook is "E_INVALIDARG (0x80070057) in HostUSBDeviceWrap. (see picture in attachment).
Thanks for your help.
