Camera object has no attribute GVSPAdjustPacketSize in v0.3.2 #85

First of all thank you for your work, I use Pymba for another camera and it works great. I tried to use it for my new camera Mako U-130-B (USB3.0) and i got the message "Camera object has no attribute GVSPAdjustPacketSize" I checked the previous post and I saw that you tried to fix the problem with the version 0.3.2 but I'm using this version and I still got the issue. For now it isn't really a problem because I can still avoiding it by writing "camera_NIR.open(adjust_packet_size=False". But this solution is not perfect because I can't change the exposure time or the pixel format ("VimbaException: Operation is invalid with the current access mode"). However I can still change it manually with Vimba viewer. I just wanted you to know that the issue is still present. Best regards.

Is the other camera an Ethernet camera? It looks like this bug is because GVSPAdjustPacketSize is called if you have the Ethernet transport layer present, even if that camera is not an Ethernet camera. I'll fix that soon.

In the meantime keep using adjust_packet_size=False. That should not affect exposure time or pixel format, which sounds like an unrelated issue. Let me know if that continues.

Yes it is! Thank you I'll continue to investigate in this case.
