Hi,
USB Audio devices don't work in windows guests on a windows host. I connect the USB device (Plantronics headset) and see the USB activity light flashing when there should be sound, but nothing heard. Bizarrely I can use the volume control on the headset which moves the volume slider in the guest, so communication is definitively happening. My host is Vista x64, tried both Win XP and Vista guests with no success. I have found a couple of references in the forums and this mailing list that this can be made to work on Linux hosts with some tweaking, but others have the same problem on win hosts. http://vbox.innotek.de/pipermail/vbox-users/2007-April/001441.html http://forums.virtualbox.org/viewtopic.php?t=3281 http://forums.virtualbox.org/viewtopic.php?t=3335 http://forums.virtualbox.org/viewtopic.php?t=3138 Seeing as there was no response on the forums other than more people with the same problem I tried to create a bug ticket, but got told that "TICKET_CREATE privileges are required to perform this operation", so here I am on the mailing list. My vbox.log at the point in time where I enabled my USB device: 00:13:59.069 PCNet#0: Init: ss32=1 GCRDRA=0x01a28420[64] GCTDRA=0x01a28020[64] ====> Last entry prior to enabling my USB device 01:02:52.913 ERROR [COM]: aRC=0x80070057 aIID={e31f3248-90dd-4ca2-95f0-6b36042d96a2} aComponent={OUSBDeviceCollection} aText={Could not find a USB device with UUID {6ba2899a-6f1f-4ace-b216-77bf544dec89}} aPreserve=false 01:02:52.918 ERROR [COM]: aRC=0x80070057 aIID={e31f3248-90dd-4ca2-95f0-6b36042d96a2} aComponent={OUSBDeviceCollection} aText={Could not find a USB device with UUID {d8c81da6-d207-4d58-b5a3-b601a9f7f27a}} aPreserve=false 01:02:52.923 ERROR [COM]: aRC=0x80070057 aIID={e31f3248-90dd-4ca2-95f0-6b36042d96a2} aComponent={OUSBDeviceCollection} aText={Could not find a USB device with UUID {a43d00bd-935b-4c0c-95b0-b926e711f2ca}} aPreserve=false 01:02:52.928 ERROR [COM]: aRC=0x80070057 aIID={e31f3248-90dd-4ca2-95f0-6b36042d96a2} aComponent={OUSBDeviceCollection} aText={Could not find a USB device with UUID {f0e7b709-d700-4f5b-9eb3-ed08adf3d22b}} aPreserve=false 01:02:56.152 VUSB: attached 'proxy 047f:0ca1' to port 1 01:02:56.161 OHCI: USB Operational Any help appreciated.
