ERROR: Cant find USB Device

[AutobotZee]

Hi. I followed the debian installation instruction and when starting the daliserver it throws me an error saying it cannot find a usb device. And I can see that my /dev has no /dali device, instead upon plugging in the device it turns up as hiddev1 in my dev/usb folder. As I am new to this can you please guide me and help me debug this error?

You would not see a /dev/dali device unless you set up udev rules to create one, and it would just be a symlink to the hiddev device you mention. daliserver doesn't make use of this anyway, it detaches the kernel's HID driver and controls the device directly through libusb.

Can you share the output of the lsusb command? daliserver is looking for a device with ID 17b5:0020 — does this show up?

HI, Thank you for the info. I think I am getting close now. I think i have to make daliserver look for 04cc:0802. This is the Device I need to connect to. The exact lsusb output is here.

No. daliserver cannot drive the Hasseb DALI interface, the USB protocol is completely different.

Does it not support any other device which is compatible to Tridonic Dali USB Adapter ( if any ? )

[sde1000]

Unfortunately there is no standard for DALI over USB, so every manufacturer does it differently. daliserver can only drive the Tridonic and Lunatone interfaces because they are actually the same device from the same manufacturer, and the author @onitake put a lot of work into reverse-engineering the protocol.

[onitake]

This is correct - I only built daliserver around the Tridonic/Lunatone DALIUSB device. I didn't have anything else available back in 2011.

If you're looking for something more generic, please consider @sde1000 's https://github.com/sde1000/python-dali project. It also supports a few other devices. It's unlikely that I will ever add more hardware to daliserver. Pull requests are welcome, though.

Lunatone interfaces because ...

Lunatone can be an alternative because it is more available in the market !
