A quick Google for fresco logic usb3.0 host controller comes up with this

When I had USB3 issues because I upgraded my old workstation to Win 10, I resolved the unsupported chipset by installing a new PCI card.

This has a power adapter on the card and I supply power to the card from one of the motherboard drive power connectors.

Looks like this might be a desktop (possibly Giga-Byte or Asus). Have you tried a camera only test (no other USB devices connected) using the manufacturer supplied cable on another machine, or even on this machine?

Where are you writing the captured frames to (I notice an external drive F connected)?

The thread title say Drop Frames ASI1600MCool but the graphic has an ASI294MC connected??

What happens if you run a camera only test (no other USB devices connected) using the manufacturer supplied cable with camera plugged directly into a laptop port?

I think you mentioned that you had USB Suspend disabled?

I connected the ASI294MC Pro to my comouter's USB3 port with the cable that comes with the camera. When changing exposure settings the camera started todrop frames and I unchecked and rechecked the camera under the Cameratab. From that point the camera continued to work fine without dropping frames.

If it's related to the USB cable I guess I'll live with it for once I get past the 1 or 2 times of it dropping frames it then continues to work for hours. Maybe somewhere along the line something will change and the problem disappear.

Thanks for trying help figure out what's happening.

Perhaps you have another machine to test the camera/cable? Also try another (short) cable to see if the problem persists.

I just took some darks with the ASI294MCPro inside and when capturing at 120sec I got up to 5 frames out of 10 and it started to drop all frames. I was using another 6 foot USB3 cable (doesn't seem to make a difference as to cable). As usual once I get past the initial drop frame sequence I don't experience dropped frames for the rest of the session. I didn't however try this with my laptop. I'll need to that next.

What is most puzzling is that drop frames occurs after 5, 6 or 7 frames and then it works fine for the rest of the session even if it's 5 hours long.

Hi Don,

can you share your log from the session please? I'd just like to check that the problem isn't to do with the maximum time allowed for the frame to arrive from the camera.

Cheers

Turned computer on tonight and previous log was over written.

No worries, just grab the log the next time it happens and I will then have a look.
Cheers, Robin
