Hi!

I have a problem with the driver. I followed the step-by-step
installation in the wiki

<snip>

hg clone http://www.jusst.de/hg/multiproto
wget -O pctv452e.patch 
http://www.linuxtv.org/pipermail/linux-dvb/attachments/20080125/b9e1d749/attachment-0001.patch
cd multiproto
patch -p1 < ../pctv452e.patch
make ; # there might be a few warnings.
cd v4l

insmod dvb-usb-pctv452e.ko
# in case some insmod complains about unresolved symbols:

</snip>

The multiproto
It compiles with an error because the patch did not apply wihtout error:

So I inserted the line into 
linux/drivers/media/dvb/dvb-usb/dvb-usb-ids.h by hand
#define USB_PID_PCTV_452E                              0x021f

I type make and all compiles with only a few warnings but now without 
any error.

When I install the modules and load them I get the following output from 
dmesg:

</snip>
usb 3-2: new high speed USB device using ehci_hcd and address 4
usb 3-2: configuration #1 chosen from 1 choice
dvb-usb: found a 'PCTV HDTV USB' in warm state.
pctv452e_power_ctrl: 1
dvb-usb: will pass the complete MPEG2 transport stream to the software 
demuxer.
DVB: registering new adapter (PCTV HDTV USB)
pctv452e_frontend_attach Enter
stb0899_attach: Exiting .. !
dvb-usb: no frontend was attached by 'PCTV HDTV USB'
input: IR-receiver inside an USB DVB receiver as /class/input/input5
dvb-usb: schedule remote query interval to 100 msecs.
pctv452e_power_ctrl: 0
dvb-usb: PCTV HDTV USB successfully initialized and connected.
</snip>

But there is no frontend loaded:

<snip>
dev:/usr/src/multiproto# ls /dev/dvb/
adapter0
dev:/usr/src/multiproto# ls /dev/dvb/adapter0/
demux0  dvr0  net0
dev:/usr/src/multiproto#
</snip>

Any idea why this happens? I followed the mails about the PCTV452e in 
the last weeks and there are several messages about a working 
installation but I do not have a frontend after loading the modules!!?

Thanks,
  Jens
