Let's get the basics out of the way...
I'm using the latest test build:
Windows 5.0.1 revision 101939
ExtPack 5.0.1 revision 101934
Host Machine:
Windows 8.1 64-bit
HP Envy dv6t-7300 laptop
Intel Core i7 3740QM CPU @ 2.7 GHz
8 GB RAM installed
Guest VM:
Ubuntu 14.04 Desktop 64-bit
Allocated 2048 MB RAM
2 CPUs
16MB Video Memory
45 GB vdi dynamic hard drive image
All other VM settings are default
VM has a fresh install of Ubuntu desktop with the test build's VBoxGuestAdditions properly installed (as other guest additions features work fine).
I'm attaching copies of the VBox.Log and VBoxStartup.log files (zipped).
The problem: Quite simply, none of my VMs can have a USB device connected to them. "Enable USB Controller" is checked, the controller type doesn't affect the problem. When I click to add a new USB Device Filter from a plugged in device, I see a greyed out "<no devices available>" message, when it should show the card reader and a USB mouse dongle, at least. I tried adding a manual filter for the specific VID and PID of the device, a USB card reader, that I'm trying to attach, but the Ubuntu desktop VM doesn't react when I plug/unplug the device from my physical machine with the filter in place, as determined with dmesg and lsusb from the guest's terminal command line. The VM specified above is the one I need it to work in, but I'm having this problem with 11 other VMs that are a mixture of Windows XP, Windows 7 and Ubuntu Desktop/Server guest VMs I have set up.
I've tried numerous reboots of my host PC; full reboots using the windows shutdown command, not the half-hibernate reboots Windows tries through conventional means. I've tried removing and reinstalling the extension pack, and although those operations complete without errors, the problem persists. I've tried starting VBox with and without admin rights with no success either way. In researching the problem I found some people having issues with USB 3.0 ports, so I tried all 4 of my ports, 3 of which are USB 3.0 and the 4th is USB 2.0, no luck with any device plugged into any port. I'm stuck with "no available devices" with all attempts to troubleshoot the problem.
Here's a bit of additional info I got after seeing other users with similar issues being asked for it:
Code: Select all
C:\Program Files\Oracle\VirtualBox>VBoxManage.exe -v
5.0.1r101939
C:\Program Files\Oracle\VirtualBox>VBoxManage.exe list extpacks
Extension Packs: 1
Pack no. 0: Oracle VM VirtualBox Extension Pack
Version: 5.0.1
Revision: 101934
Edition:
Description: USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption.
VRDE Module: VBoxVRDP
Usable: true
Why unusable:
C:\Program Files\Oracle\VirtualBox>VBoxManage.exe list usbhost
Host USB Devices:
<none>
C:\Program Files\Oracle\VirtualBox>It's worth mentioning that this is the first time I've tried attaching a USB device to a VBox VM in years. So this could be specific to my machine and my windows host. I needed to set up a dev environment today that required it access a USB card reader and here I am... 12 hours later.
I've kinda run out of things to try... I'm hoping the problem I'm having is something simple I'm missing, but going through the logs myself, it doesn't appear there are any errors that would even lead to a place to look closer. I feel like I've either uncovered a legit bug or I'm missing something. I'll let the pros have a look and comment at this point.
Feel free to ask me to dig up any more info that may help. I'm a developer with years of software and hardware troubleshooting experience. I'm also open to a phone call and/or join.me session if necessary.
