dvb_usb_rtl28xxu: regression with MSI Digivox mini II v3.0? Or USB3 problem?

Hi folks,

I tried to reactivate my USB DVB-T receiver I had successfully working many moons ago on a previous OpenSUSE version.

The module loaded, but scanning for stations did not produce proper results. Looking at the syslog messages when plugging in the devices shows

I started playing around a bit, loading the “fc0012” module by hand and unplugging/plugging the USB device several times, when suddenly I noticed that the tuner now was recognized:

Should I expect this setup to work?

Hi Jens
Looking on the web, seems you need to see “Realtek RTL2832U reference
design successfully initialized and connected” in dmesg output, if not
things are not going well… Maybe find a USB 2 hub to connect to, or
check the system BIOS for legacy support?

Hi Malcolm,

sorry for the late reply - I’ve been on the road without access to a USB hub

I had a look at the driver source - for one, the card type string is dynamically adjusted to the USB id, so seeing ‘Dexatek DK DVB-T Dongle’ instead of ‘Realtek RTL2832U reference design’ is expected… and I can see “dvb_usb_v2: ‘Dexatek DK DVB-T Dongle’ successfully initialized and connected” in my dmesg output.

Now that I had access to a USB2 hub, I plugged that into the machine and then plugged the DVB-T card into the hub. The messages were the same (except for the USB bus id, of course) and the I2C problems remain.

From what I can tell, it boils down to not being able to properly communicate via I2C. As that is internal to the DVB-T stick, my gut feeling is that I’m facing a regression.
