Hello has anyone running this device stable? I see an unstable
behaviour, but I am not sure if this is software related or if this is
my hardware.
At first everything seems ok and I can watch TV as expected, but after
some arbitrary time (5 min - 24 hours) the device stops to work and I
get the following message:

kernel: uhci_hcd 0000:00:07.2: host system error, PCI problems?
kernel: uhci_hcd 0000:00:07.2: host controller halted, very bad!
kernel: uhci_hcd 0000:00:07.2: HC died; cleaning up
kernel: usb 1-1: USB disconnect, address 3
kernel: dvb-usb: bulk message failed: -19 (6/0)
kernel: dib3000: while sending 0x0001 to 0x0404.
kernel: dvb-usb: KWorld/ADSTech Instant DVB-T USB2.0 successfully
deinitialized and disconnected.

Is there anybody, who is running this device? What is the best way to
debug this issue. I have got the newest stable kernel (
installed with the newest patches from linuxtv.org. I see the same
behaviour with 2.6.12, although I have the feeling the crashes are
less frequent with the newer kernel.
