[pvrusb2] HVR-1950 encoder appears to be stuck error messages

Tue Mar 31 23:27:07 CDT 2015

Hi. This list seems to be somewhat dead, but when I try searching on my 
issue, results from this list always come up. So it seems worth a try to 
ask for some help here.

I got a couple of these tuners used for a pretty good price and am 
currently trying to test them. I'm want to determine at this stage whether 
they are functional so that, if not, I can send them back to the seller 
for a refund.

The target system is a new Gentoo install on the Liva X, which is also 
running MythTV. So I've hooked up the tuners, loaded the firmware 
(firmware gotten via Gentoo) and modules, gotten them recognized in 
mythtv-setup--and even written udev rules--and am trying to proceed 
further.

I tried a channel scan under mythtv-setup, which gives some odd results; 
I'm not any kind of myth-guru, so maybe the results are only odd to me. 
The scan does finish and seems to find channels or to update channels, but 
it finishes with the message "no new channels found."

When I attempt to watch live TV through the MythTV interface, though, the 
only channels I can seem to tune are 5 and 6: trying others results in 
either a blank black screen or an error message (something like "failed 
jump"). So something is not working right here. Perhaps I should mention 
that I'm using the up/down arrows on an attached keyboard to select 
channels (no remote). In any case, those may be MythTV issues, or MythTV 
user issues, which cannot be addressed here.

But what perhaps can be addressed are errors I'm seeing in dmesg output. 
Both tuners output the error message seen in the subject heading of this 
e-mail as I try to tune stations.

I'll append below some dmesg output that may provide further insight into 
the issues I'm confronting:
