We recently invested in a couple Pleora U3 HDSDI to USB3 Vision capture devices. They work extermely well with NI Vision, except when you are plugging and replugging them. Here is the sequence of events when it fails: To start with I have a U3 plugged in and working. MAX looks like this:Now if I unplug it, MAX transitions to this view. The U3 has disappeared. Now if I replug it in, I get this (the pleora U3 shows back up): Notice that the u3 isn’t selected (Ni USB-6009 is). If I select the U3 MAX hangs for about 10 seconds and then returns an error and the below is what I see. I also waited for the lights to stop flashing on the U3 HDSDI (to make sure it's all happy and running) before clicking on it in MAX. So I click OK on the error and I get this status in MAX. Notice the red “x” circle on the U3 entry. I can't do anything with the device, its essentially dead to the world. Now if I unplug it, MAX shows it disappear: Now I replug it in I get this: Now when I click on it, everything is working and happy. It litteraly happens every other unplug and plug in. You plug it in a single time, doesn't work. You plug it in a second time and it works. You plug it in a third time it doesn’t work. You plug it in a fourth time and it works. Just to prove I'm not crazy, I will now unplug it and replug it a third time. See you get the failure: On the fourth plug in, MAX crashed. It usually doesn’t do this, and I think it was because I left the error window open when I replugged in the U3. For what it’s worth I usually close it before replugging in. When I restarted MAX it opened the U3 just fine. For grins, I tried opening and closing the camera in LabVIEW to see if this is a MAX issue. With the U3 working in MAX, I closed MAX and wrote a little LabVIEW program to open the U3 and close it. Here is the code: And when I run it, I get no errors: Now if I unplug and replug (not opening MAX at all) and when the lights on the U3 stop blinking I run my little program. In this case the U3 opens and closes just fine with no errors. If I open MAX up after running this, it opens the U3 just fine. This makes me believe it may be some interaction with MAX and the Pleora device. I've worked with the engineers at Pleora and they don't think it is on their end, and wanted me to expore this being an NI problem. Soooo, am I crazy or is this a known issue? Are there any work arounds other than telling my production techs to unplug and replug untill it works everytime they install a new one? FYI, We are running Vision 2016 on all our PCs and this is with MAX version 15.3.0f0

MAX Doesn't Reconnect to USB3 Capture Device

Just wanted to update this thread after I've spoken with Pleora:

They said they have resolved this issue in their firmware trunk, but it's not made its way into a release yet. My contact at Pleora says that he will inquire about the timeline for a release with this fix. Once I hear back with a time frame, I'll update the thread again.

Update: Pleora said that their general timeline for a release with this fix is between 6 and 8 months out.
