Hello List,

I'm trying to get dvb-t via usb to work with my NAS.
Because the NAS got some hardware not supported by the mainline kernel
I can not simply update the kernel.

After some time I figured out how to load the firmware without
udev/mdev. But still I get a a error message:


...
drivers/media/dvb/dibusb/dvb-dibusb.c: bulk message failed: -110 (1/0)
usb 1-1: events/0 timed out on ep1out
drivers/media/dvb/dibusb/dvb-dibusb.c: bulk message failed: -110 (1/0)
usb 1-1: events/0 timed out on ep1out
drivers/media/dvb/dibusb/dvb-dibusb.c: bulk message failed: -110 (1/0)
usb 1-1: events/0 timed out on ep1out
drivers/media/dvb/dibusb/dvb-dibusb.c: bulk message failed: -110 (1/0)
...

Im not really sure if its a usb or a dvb error. But all other usb
devices are working so far ...


The card is recognised as:

Grandtec USB1.1 DVB-T/DiBcom USB1.1 DVB-T reference design (MOD3000)

and the green light is burning after the firmware is loaded.

I created the following devices:

mkdir -p /dev/dvb/adapter0
mknod /dev/dvb/adapter0/frontend0 c 212 3
mknod /dev/dvb/adapter0/demux0 c 212 4
mknod /dev/dvb/adapter0/dvr0 c 212 5
mknod /dev/dvb/adapter0/net0 c 212 7

If anybody can give me a hint what I'm missing would be great.
