TT-Connect CT2-4650 CI doesn't initialize (Timeout?)

Question

I've tried to get a Techno Trend TT-connect CT2-4650 CI running under a Kali Linux, where I suppose the kernel is about the same as on a current Debian.

The compilation ran just fine.

The kernel module got loaded with no problems, but when I connect the device to my virtualbox I get the following messages in dmesg:

110 seems to be a Timeout issue, I can't quite see why though.

Any ideas are greatly appreciated.

Have you run the shell script in the media_build-tt folder?

Best is to remove your media_build-tt folder, extract the archive again and run the following steps:

1. Change into the media_build-tt folder and run one of the following shell scripts:

   ./v4l/build_x64.sh       # 64 Bit kernel without DVB-C support<br />
   ./v4l/build_dvbc_x64.sh  # 64 Bit kernel with DVB-C support
   
   ./v4l/build_x86.sh       # 32 Bit kernel without DVB-C support<br />
   ./v4l/build_dvbc_x86.sh  # 32 Bit kernel with DVB-C support
   

2. Then run make and make install (the later as root or per sudo).

I'm using Debian GNU/Linux testing and the adapter (haven't tested the CI slot) is working from kernel 3.11 to 3.12 - but has some problems waking up from sleep unfortunately.
