I have one Avermedia Avertv Hybrid Volar HX tuner. This device is a USB2 stick and is not yet supported in Linux (long nights of checking here). I maintain one WINXP installation in VirtualBox just for these cases that something can't be done in Linux.

Well... the thing doesn't work. When I attach the device is recognized by the Windows and by the Avermedia software but it doesn't work. I can't scan for channels and I cant tune. When it tries to scan for channels I don't see any dot blinking in the USB icon in VirtualBox, meaning that there is no USB activity.

Just to check if there is any problem with the device, I did a normal winxp installation (not vm) in my spare disk. There everything worked fine.

IS there any kind of limitation in the VirtualBox for this kind of things? Is it even possible to be done what I am trying to do?

I am running Arch Linux and VirtualBox 1.5.4.

A guy on a post here told me that virtualbox makes you use the paid version of virtualbox for usb support. They didn't GPL the usb code. I haven't looked it up though.

I am using the closed source version which is free for personal use. I have USB support as I can plug USB sticks and I can use my printer. There must be something else

Please tell me. Did you resolve this problem?
I have this USB device too, and I need to use Vista on my notebook just for watching TV :-( For the all other things I have linux :-)

Bull shit, I have used Virtual Box OSE and had USB 1.1 and 2.0 support.

No I didn't solve the problem. I still have to reboot to XP to use this device.

Hi all!

I have exactly the same problem. I have an Avermedia AverTV Volar HX, which has no Linux support. OK, no worries, let's install Windows XP in a VirtualBox 2.0.2. I have the non-opensource version, which is free for personal use, and contains full USB support. XP is up and running, and it recognises the Volar HX, I can see it in the Device Manager under the "Sound, Video and Game Controllers" title. The AverTV software is also installed, and everything seems to be fine. USB filter status in the VirtualBox is claimed to be "Captured", the little checkbox in the Devices -> USB Devices menu of my VirtualBox window is ticked. When I start the AverTV software in my running XP, I can see only a black screen where I should see the TV broadcast. I start scanning for channels, and it seems to find a lot of channels, and the little checkboxes next to the channel numbers in the setup window are all ticked. Yet when I click on "Apply", and start surfing the seemingly found channels, all I get is a black screen, no sound, no video. I also tried attaching a VCR to the device, and changing the input source to "composite video" or "S-Video" - all I get is the black screen. DirectX 9 is installed in my Windows XP, so is Service Pack 2, meaning that I definitely don't lack USB 2.0 support. I have no clue.
The device works fine in Vista (I have dual boot).

By the way, I also have an ACER CrystalEye Webcam (working fine and out of the box with Linux). I also enabled the USB filter for this device in my virtual machine, and as a result, the Windows XP running in the virtual machine immediately recognised the device, and installed the driver for it. When I go to "My Computer" in my XP, I can see it as "USB Imaging Device". Normally, when I double click on it, I should see the image frames from the webcam. Instead, I see an empty grey box. The status for the USB filter of this device in VirtualBox is the same, "Captured". It seems it has the same problem.

Maybe this is the right direction to move forward: to check if there was any other possible state for a USB device with an active filter than "Capture". Otherwise I have no idea.

Cheers,
Peter

I think VirtualBox 2.0.2 do not "understand" how to work with this device. Maybe because of linux kernel do not support it yet. I heard rumors what some one wanted to create the driver for this Avertv Hybrid Volar HX. But it's only a rumors. The official tech support of Avermedia still could not tell me anything giving a hope for linux support

In the linux-dvb mailing lists there were messages stating that the driver would be ready in some weeks. These messages are dated back in December 2007 - January 2008. Since then as many times I have goggled I didn't find anything new.

This is the first message of the thread.

Maybe the project was abandoned or maybe it is very difficult to be completed.
