Hi!

I am using a Freecom DVB-T usb device which has the usb id 14aa:0225
before the driver / firmware is loaded. My system is gentoo linux with
2.6.17-gentoo-r8 kernel source. I download the latest snapshot of the
linux-dvb drivers via mercurial and installed them. I took the firmware
named dvb-usb-wt220u-fc03.fw. When I modprobe dvb_usb_dtt200u I get:

dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)'
in warm state.
dvb-usb: will use the device's hardware PID filter (table count: 15).
DVB: registering new adapter (WideView WT-220U PenType Receiver
(Typhoon/Freecom)).
DVB: registering frontend 0 (WideView USB DVB-T)...
input: IR-receiver inside an USB DVB receiver as /class/input/input8
dvb-usb: schedule remote query interval to 300 msecs.
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom)
successfully initialized and connected.
dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)'
in warm state.
dvb-usb: will use the device's hardware PID filter (table count: 15).
DVB: registering new adapter (WideView WT-220U PenType Receiver
(Typhoon/Freecom)).
DVB: registering frontend 1 (WideView USB DVB-T)...
input: IR-receiver inside an USB DVB receiver as /class/input/input9
dvb-usb: schedule remote query interval to 300 msecs.
dvb-usb: WideView WT-220U PenType Receiver (Typhoon/Freecom)
successfully initialized and connected.
usbcore: registered new driver dvb_usb_dtt200u
dvb-usb: recv bulk message failed: -110

Now I am quite confused why I find two directories in /dev/dvb named
adapter0 and adapter1 with

adapter0:

crw-rw---- 1 root video 212, 4  2. Okt 16:50 demux0
crw-rw---- 1 root video 212, 5  2. Okt 16:50 dvr0
crw-rw---- 1 root video 212, 3  2. Okt 16:50 frontend0
crw-rw---- 1 root video 212, 7  2. Okt 16:50 net0

adapter1

crw-rw---- 1 root video 212, 68  2. Okt 16:50 demux0
crw-rw---- 1 root video 212, 69  2. Okt 16:50 dvr0
crw-rw---- 1 root video 212, 67  2. Okt 16:50 frontend0
crw-rw---- 1 root video 212, 71  2. Okt 16:50 net0


I can dvbscan on both adapters with correct behaviour (but not at the
same time) and vlc shows tv when using the generated channels.conf.

I would like to use vdr for recording but this gives me a lot of errors
(adapter1/demux0: too many open files ... and more).

Can anyone tell me why I got to devices? dmesg looks to me like the
firmware loads twice. Also two ir-receiver are registered and the
class/input/inputX increases every time I unload and load the
dvb_usb_dtt200u.


Thank you very much for reading this.

Bye
Peter
