When trying to scan DVB-C MUX the Linux (Debian) driver crash.
I´m using the latest driver from http://sundtek.de/media/sundtek-netinst-driver.deb

[Sundtek]

What does "dmesg" show up?

Is the device attached to a USB 3.0 port?

Only use the latest driver.

possibly contact us via chat either Skype (Sundtek) or http://chat.sundtek.de
I guess something else is wrong on your system, we're using those devices every day now and also tvheadend is running permanently with it on our NAS.

[jimmers]

Is the device attached to a USB 3.0 port?

Yup.

Changed to a USB 2.0 and now it works.

[Sundtek]

Please note this is not a bug of our driver, but a bug of the Linux system in general at the moment.

[jimmers]

But I´m still having issues with random crashes.
It may work for about 10-30 min I think.

[Sundtek]

Do you have another Linux system? There is some networking mode available so you can stream the entire device to Linux.
This very likely seems to be a usb controller issue on that system, what PC is that?

You might also try to switch to isochronous transfers this would be the second option that is available

/opt/bin/mediaclient --dtvtransfermode=iso -d /dev/dvb/adapter0/frontend0

afterwards reconnect the device

If you have a look here someone had a similar issue with a usb harddisk
http://ubuntuforums.org/showthread.php?t=1972450

A kernel Update was required in his case actually.

[jimmers]

I´m running an old Debian dist with kernel 2.6.32-5-amd64.
I will try to upgrade, if possible, later tonight to a newer kernel.

[Sundtek]

I guess you would need some older hardware for this old Kernel, we tested the device down to 2.6.15 (but also with old hardware which had mature USB controller driver support). USB 3.0 controllers are definitely not well supported with those old kernels.

[jimmers]

I have now updated the whole system to Debian wheezy.
But I have the similar disconnects on the USB.

I do not get this, now when using USB 3.0 it seem to work.
But not if I connect to the USB 2.0 port.

What does lspci show up?

Yet it's still a bug in the USB controller driver of linux which affects you.

AMD ... I thought so. USB Controller drivers for their boards need some workarounds.
Do you have any other Linux based system? You could stream DVB-C to that PC and create a virtual interface.

Small embedded boards like beaglebone black or several USB 2.0 based NAS systems also work nicely with it.

[jimmers]

I have not have any issues today since the update to the latest kernel and using the xhci_hcd instead of ehci_hcd. But I have not restarted the computer since I got it to work so hopefully this won´t create any issues further on.
