Hello list,
I have an "Avermedia A835B(1835)" USB DVB-T stick (07ca:1835) which
works only (very) sporadically. It's pure luck as far as I can see.
I can't reproduce how to get it working. There are no special steps that
I can take to guarantee that it'll work once I plug it in.
I'd rate my chances of having the device actually working between 5 and
10 percent.
In the log everything looks fine, apart from the messages at the bottom
about the device not being able to get a lock on a channel.
Reception here is really good, so there's no problem with signal
strength. When loading the device in Windows 7 64 bit it always finds a
lock.
Has anybody any idea? Thanks for any suggestions!
