Hello Hans,
That device is working very, thank you for it. Anyhow, I noticed two things.

1) it does not start transmitting just after I plug it - I have to
retune it!
Output says it is tuned to 95.160000 MHz by default, but it is not.
After I issue retune, just to same channel it starts working.
$ v4l2-ctl -d /dev/radio0 --set-freq=95.16

Can you try this patch:


It does not resolve the problem. It is quite strange behavior. After I
install modules, and modules are unload, plug stick in first time, it
usually (not every-time) starts TX. But when I replug it without
unloading modules, it will never start TX. Tx is started always when I
set freq using v4l2-ctl.

If you replace 'false' by 'true' in the cmd_main, does that make it work?
I'm fairly certain that's the problem.

Nope, I replaces all 'false' with 'true' and problem remains. When
modules were unload and device is plugged it starts TX. When I replug it
doesn't start anymore.

I just added msleep(1000); just before keene_cmd_main() in .probe() and
now it seems to work every-time. So it is definitely timing issue. I
will try to find out some smallest suitable value for sleep and and sent
patch.

Have you had time to find a smaller msleep value?

Nope, but I will do it today (if I don't meet any problems when upgrading to latest master).

regards
Antti
