Comment 1 for bug 61181

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.
