Bug Description

dmesg output

dvb-usb: found a 'WideView WT-220U PenType Receiver (based on ZL353)' in cold state, will try to load a firmware
[11138.365712] dvb-usb: did not find the firmware file. (dvb-usb-wt220u-zl0353-01.fw)
-------------------------------------------------
It clearly should be added to the firware folder as part of the distribution, I was testing knot3

Sorry, your bug have stay a long time unnoticed I suppose because it was not assigned to a specific package.

I see on my Gutsy system:
paul@Arcturus:~$ ls /lib/firmware/2.6.22-7-generic/dvb-usb-wt*
/lib/firmware/2.6.22-7-generic/dvb-usb-wt220u-01.fw
Does it work with your (ZL353 based) device?
I wonder if it would not be time to update to ...-02.fw
I guess it would help if you could run in a console:
sudo udevmonitor
then plug your device, and then post the result in a comment to this bug (ideally as an file attachment).

Some info I found:
http://www.wv.com.tw/products-wt-220u_main%20frame.htm
http://www.linuxtv.org/downloads/firmware/dvb-usb-wt220u-02.fw (this is not the zl0353 version, so does not know it if fits)
This file should be put in /lib/firmware, maybe under the kernel version directory.
Found on
http://linuxtv.org/wiki/index.php/DVB_USB#WideView.2FYakumo.2FHama.2FTyphoon.2FYuan_Boxes_and_Pens :
WideView Pentype DVB-T-Receiver (WT-220U) USB2.0/USB1.1 dvb-usb-wt220u-01.fw Pen-sized

Re-assign to kernel, udev ships no firmware itself

Changed in udev:
assignee: dufresnep → nobody

How do I or you close this bug, myself I have copied the firmware from release
to release. My usbtv requests this particular firmware and now that it is
available naively there is no bug or feature problem

Sorry about not replying to your first inquiry re ~~02.fw I cannot test this
since I do not have a spare PC to install gutsy on and I do not know what
this version of the usb-tv-stick module will request - why not just include
all the firmware for this driver which is what my original complain was -
there was my device recognized but with no firmware to download ? even though
the module and firmware came from the same site

There are three firmwares used by this driver:

dtt200u.c:173: .firmware = "dvb-usb-wt220u-02.fw",
dtt200u.c:218: .firmware = "dvb-usb-wt220u-fc03.fw",
dtt200u.c:263: .firmware = "dvb-usb-wt220u-zl0353-01.fw",

Each individual firmware image is used specifically, depending on which device is present. One firmware image is _not_ a replacement for another.

This bug probably should have been filed under linux-ubuntu-modules-2.6.22

The DVB-USB kernel documentation (Documentation/dvb/README.dvb-usb) refers users to the web-site to locate the appropriate firmware:

From my research it appears that although the kernel source-code refers to this firmware image the site that hosted it, http://www.thadathil.net/dvb/fw/ (pointed to from http://www.linuxtv.org/wiki/index.php/DVB_USB#Firmware) is currently off-line.

In which case a better source of firmware would be
http://www.linuxtv.org/downloads/firmware/

which is pointed to by the first 'here' in the below reference

These are not 'pristine source' just blobs which need a reliable source

Indeed. That was the point of my comments. The kernel source-code contains a reference to a firmware image (dvb-usb-wt220u-zl0353-01.fw) *not hosted at http://www.linuxtv.org/downloads/firmware/ but was, according to a Google search, hosted at http://www.thadathil.net/dvb/fw/.

The DVB-USB documentation refers users to http://www.linuxtv.org/wiki/index.php/DVB_USB#Firmware where a hyperlink leads to the off-line 'thadathil.net' site.

I found the firmware file on http://raaf.atspace.org/dvbusb/firmware/

Why has this been reassigned to udev? If the kernel now includes the firmware properly, udev should load it automatically

Changed in udev:
status: New → Invalid

(I should also add that if udev doesn't load the firmware, then it's probably still a kernel bug for specifying it incorrectly)

Some progress here?

linux-restricted-modules-2.6.24 for hardy includes dvb-usb-wt220u-02.fw, but it's not sufficient?

No, I have two "identical" Freecom DVB-T USB sticks. They need different firmware. One requires dvb-usb-wt220u-02.fw, whereas the other requires dvb-usb-wt220u-zl0353-01.fw.
