Not working with VirtualBox

[derabbink]

I have a MediaTV Pro III that I want to use for DVB-C. I currently trying to figure out how everything works using an Ubuntu 12.04 x86_64 VM, hosted by VirtualBox.
On my provider's network, at least one DVB-C channel is unprotected and freely available.

The problem I have is that scanning, using the scan and dvbscan utils, does not seem to work:

Code: [Auswählen]

$ scan /usr/share/dvb/dvb-c/nl-Ziggo

I installed the latest drivers from the .deb file. What I noticed is that there is currently no /etc/sundtek.conf file on my system; the installer didn't create one.
In my VirtualBox USB configuration, I have checked "USB 2.0 (EHCI) Controller". This may be relevant, considering my /var/log/mediaclient.log (see below) and this post.

How can I make this work on VirtualBox?

I set the logging level to max (/opt/bin/mediaclient --loglevel=max) and this is what I got in /var/log/mediasrv.log while trying to scan:

When I looked in the /var/log/mediaclient.log, I discovered a bunch of lines similar to the following; although I'm not sure how they relate to my scanning attempts:

Code: [Auswählen]

2014-05-19 17:10:56 [20535] connection to driver service timed out

[Sundtek]

I would not wonder about that, try to use the network infrastructure of the driver with Virtualbox.
USB Pass through performance in virtual machines is usually not the best one.
