USB relay (HID interface) as shutter release device. Help! - by: m.baldassarre.85

Hi everyone,
I'm new on this forum. I've recently bought this USB relay from Amazon ( www.amazon.it/gp/product/B00W3GRQNI/ref=...00_s00?ie=UTF8&psc=1 ). I intend to use it as a shutter release device for my Nikon D200. However, it has a HID interface, rather than a serial one, which is giving me a headache to configure. I'm running Kstar/Ekos under Xubuntu. This is what I get when I run lsusb:




And this is what I get when I run dmesg:



First, I am not able to any address for it in /dev. I have tried setting /dev/uhid, /dev/usb/hiddev0 and /dev/hidraw0 as shutter release ports in Indi, but no luck. I don't think this approach is going to work, as Indi should know how to send Hex ON/OFF commands.

Is there a way to use this device as a shutter release? If not, I will go on and buy a USB relay with a serial interface (I was considering buying this one: sigma-shop.com/product/7/usb-relay-contr...one-channel-box.html ). I should be able to see it as /dev/ttyUSBx, right?

Thanks for your help!

Maurizio
