Question

Hi,

I used Backyard EOS for several times now, and on some occasions, after X amount of time the conection with my camera is lost.

The camera used is a Canon T6i, and i use a brand new USB cable (one lead C to mini)

After the conection is lost, a can't seem to get it back , laptop makes a very strange noise when i try to connect, the only thing that help is to shut down BYE and plug the camera in a other USB port.

I'm no IT specialist, so i hope to get a solution here.

Log file from a test i did indoors yesterdy in attachement.

 

Thank you

All camera connection lost are either due to low level battery, a driver issue, or a physical cable/connection issue.

Since you can connect the camera initially I would tend to think that this is not a driver issue.

Try connecting the camera in a different computer port?  

Are you using a usb hub?  How many devices do you have on the USB hub?

Hi,

i connect directly to the laptop  with a new cable, no HUB.

I have 4 USB ports on my laptop, all of them are in use during a AP session : Guide Camera, Hand Corntroller for slewing from Stellarium, Canon and USB mouse dongle.

Also i use a batterygrip on my camera, topped up for every session, so battery power is not an issue.

After connection is lost, i have to shut down BYE and use a different USB port to get it to connect again.

I would suggest that you make sure that you have disabled the Power Saving feature that shuts down the laptop's USB ports to save power. It should be available via the Control Panel.

Hi,

 

yes, done that after it cost me some some exposure time one time ;-)

If the camera disconnects during a session this is due to a physical connection being interrupted.  Even a 1ms interruption will cause the Canon SDK to fire a camera disconnect event and since the camera won't connect after this unless you change the port kinda points into this direction too.

When you connect the camera in a different port after it disconnects, do you leave it into that port? And does it eventually disconnects from that port too?

Do you have USB ports on 2 sides of your laptop?  If yes connect the camera on the other side.  This seems weird but inside your laptop usb ports on difference sides will often be on a separate internal USB bus and this may solve your issue if the internal USB bus is saturated with data.  If you have a guide camera make sure it is connected on the opposite side.

Regards,

Hi,

these are good tips, i'll give them a try !

Can't remember a lost connection after i've changed the camera to the other port witch is indeed on the other side of the laptop.

I'm currently running a test on that other port  so far so good, but only 18 mins in the test.

Thanks for the replies, i will post my findings.

Regards
