RE: [open-lighting] Velleman K8062 stops working after serveral seconds

Try a powered USB hub and see if that fixes it. Maximum current available from the RPi USB port is limited and it dies with many common USB DMX interfaces.

Subject: [open-lighting] Velleman K8062 stops working after serveral seconds

 

I installed OLA Version 0.8.26 on my raspberry pi and connected a Velleman K8062 (bought 03/2013, unmodified) to it. In the beginning all works fine, but after a few seconds no DMX-commands are transmitted anymore.
This is in the logfile:

-7 is LIBUSB_ERROR_TIMEOUT . Is there anything in dmsg?

Simon

[Stephan Nachtsheim]

no, after the connection of the usb device, there is no further entry in dmesg:

Unfortunately, it makes no difference if i use a powered usb hub or not

kind regards

Try editing ~/.ola/ola-usbdmx.conf and setting libusb_debug_level to
3. That should print some more logs.

Hello together

 

Unfortunately, i have exact the same problem. I have a new Velleman K8062, which is working without any problem on a windows machine.

when i try to use it with OLA the interface is stop working after 3-10 seconds.

 

I tried it with a powered USB-Hub and with different versions of Raspbery ola.

 

I changed the log-Level to 3. 

 

Here is my log output:

---------------------------------------------------

Has somebody some ideas, where the problems come from???

 

Thanks for any answers

IMO, I would blame the Raspbian/Pi combination. It seems to work well with a FTDI based USB interface. Use any other USB interface and your mileage may vary. Something I haven't tried yet is running OLA on another Pi distro.

-MH

[DeadRinger]

Does anyone have an update on this issue?  I am getting the same problem here, with latest builds of Raspbian and the OpenDMX release.  Tried various powered hubs, but they make no difference.  Error logs very similar to the above.  The K8062 seems to work fine on other linux machines.

Best regards

[Andrew Raby]

I'm having the same problem system will function fine on a PC but not on the PI interestingly enough the same problem presents on 2 pieces of PI software DMXWheel and OLA

 

Does anybody have any update on this work around I need to get this running ASAP

 

Cheers

Should also say that it wont pick it up through a Powered USB hub admittedly its a cheap hub but its still not seeing it in the OLA system

I'd ditch the K8062. It's possibly the worst interface out there.

One of our Lightkey users has the same problem on OS X (10.10.5 on MacBook Pro). After a few seconds, DMX output stops with this message:

2015-12-10 00:11:36.396 plugins/usbdmx/VellemanOutputPort.cpp:293: USB return code was -7, transferred 8

2015-12-10 00:11:36.396 plugins/usbdmx/VellemanOutputPort.cpp:156: Send failed, stopping thread...

Output continues (for a few seconds) when restarting OLA. On the same machine, output via FreeStyler in VMWare does work. The problem does not occur on other Macs.

Is there any progress on this?

[Peter Newman]

Not really unfortunately Simon. Similar to the user above, can we have some more logging, with libusb debug turned up to 3 or 4. Can they update to the latest OLA please, it may be fixed, or at least different in 0.9.8.

[Simon H.]

Thanks for the reply Peter. I will try to get the log output, but I can't ask the user for that and unfortunately I have been unable to reproduce the problem myself so far. We also hope to ship the latest OLA version with Lightkey soon, but it's not a top priority and will require a lot of testing. Anyway, I did not find anything in the release notes related to this issue.

[Simon Newton]

The K8062 are notoriously flaky on top of just being poorly designed
overall. See https://wiki.openlighting.org/index.php/Velleman_K8062

I think I recommended early on that you (LightKey) don't claim support
for the K8062 on your website, this is why.

We could add retry logic to the code but I think I tried that in the
past and it didn't help.
