Please describe your issue below:
I have a question about the USB ports on the Vim4. For a while I used an industrial camera on the vim4 (under ubuntu), which was supposed to work on USB 3.0 but I don’t know why the port didn’t recognise the camera, on the other hand the camera worked on the USB2.0 port which surprised me at the time but as it worked it was fine with me. The camera I use recently underwent some minor modifications and since then it’s been impossible for the Vim4 to recognise it, whereas the new camera works on my computer running both Windows and Linux. So my question is, do the USB ports on the Vim4 not recognise certain types of USB connection and if so, which ones?
(I’ve also tried connecting the camera to a USB HUB plugged into the Vim4 and the camera doesn’t work, but it is detected).
You should see the device being recogized then removed.
Might be better off to get rid of that camera and buy a new one. If its flaky now, it will only get worse. You did not say what happened to the camera, settings??
The old camera I used on the USB2 port and then they modified the FPGA of the camera which now only works on the USB3 port.
But I tried to use the camera on others vim4 thinking that my USB port might have a problem and it still didn’t work, until I tried to use the camera on the vim4 NPU and the USB3 port worked without a problem. I therefore think that the USB3 port on the basic vim4 has a problem with certain devices.
I can concur with this. I have the older VIM4 and when a USB 3.0 device is connected to the USB 3.0 port, the port resets every 30-60 seconds.
I am not experiencing this problem with USB 2.0 devices plugged into the USB 2.0 port. Furthermore, I am not having the problem with USB 2.0 devices plugged into the USB 3.0 port or with those same USB 3.0 devices when plugged into the USB 2.0 port. The problem of constant USB 3.0 port resets only occurs when USB 3.0 devices are plugged into the USB 3.0 port.
I’m even using VirtualHere Server to host USB devices to Windows machines, with no problems when USB 3.0 devices are plugged into the USB 2.0 port and USB 2.0 devices are plugged into the USB 3.0 port. I’m also using a USB 2.0 hub without any problems when done this way.
Edit:
I have to provide an update. After posting this comment, I tried to reconnect a USB 3.0 Flash drive to the USB 3.0 port, to confirm that I was still having the problem and strangely enough I had no problems with the USB 3.0 port resetting, so I connected a SSD to the port, no problems. Then, I connected 4 SSD through a 4-port USB 3.0 unpowered hub and no problems!
I’m able to read and write to all the drives without any port resets, at least for the time being.
Hello all, i’m experimenting same type of issue, i use UVC cameras. they are detected on USB2 ports but i need to have trhe USB3 bandwidth. uvc cameras are not detected on my VIM4, i’m starting to think that it seems to be related to some drivers issue.
Do you manage to have usb3 now on VIM4 basic?
Thanks
