View Full Version : DMK51 + USB3 = No video

I've been using my DMK51 connected with a USB2 hub and it works great. Recently, I've upgraded my USB infrastructure to USB3 and all of my USB2 devices (including other CCD cameras) work normally except for the DMK 51. Windows 7 can see the camera and my applications can connect to it but there is no video stream coming from the camera. This also happens with the IC.Capture.AS program (which reports no video stream).

I've installed all the latest drivers but nothing has helped. Can you help me to find a way to make this camera work on USB3 hubs (like all my other USB2 devices do)?

Thank you,
Jonathan

Hello

You camera runs on USB 3.0 with half frame rate only. It is a known issue of all 21,31,41,51AU cameras. Unfortunately we have no solution for this right now.

Stefan,
I've just upgraded my computer which has USB3 and a USB2 port.
The DMK41 (Firmware rev 1014) and drivers 2.8.9.1466 seems to work OK (full frame rate) on the USB2 port.
BUT the DMK51 (Firmware rev 1030) with the same driver will only work at a max of 7.5 fps on the USB2 port.
Is this a known issue???
Can the firmware be updated to resolve this issue?
Ken

Stefan,
Thanks for the reply.
I hoped, as the DMK41 appeared work to OK that the issue with the DAMk51 could also have been solved........

With regards to USB issues, I have had those poor frame rate issues with DBK31.
I found that on MY HP Laptop if I disabled USB 3 XHCI mode in the bios the Camera speed increased.
Previously I could only run at 15.00 FPS and this increased to full 30.00 FPS.
I also have USB legacy support enabled in the bios.
Imaging source driver 2.8.9 was used for tests.

Hope that helps!
