Image acquisition toolbox support for Daheng Mercury USB3 cameras

I am not able to interface with a Daheng Mercury USB3 camera (model MER-502-79U3M) using the Image Acquisition toolbox. Could I please have some help in getting this to work, or receive confirmation that it is not supported. The camera is compatible with GenICam, so I have installed the GenTL add-on for the toolbox.

I am able to take pictures and view live video using the default manufacturer software GalaxyView, so the camera is installed correctly. I am using 64-bit Windows 10 and obviously plugging the camera into a USB3 port.

Typing 'imaqhwinfo gentl' with camera plugged in, I see:

AdaptorDllName: 'C:\ProgramData\MATLAB\SupportPackages\R2017a\toolbox\imaq\supportpackages\gentl\adaptor\win64\mwgentlimaq.dll'
AdaptorDllVersion '5.2 (R2017a)'
AdaptorName: 'gentl'
DeviceIDs: {1x0 cell}
DeviceInfo: {1x0 struct}

Using imaqsupport, the generated text file shows (under the GENTL heading):

GENICAM_GENTL64_PATH = C:\ProgramFiles\Daheng Imaging\GalaxySDK\GenTL\Win64

Producer found = C:\Program Files\Daheng Imaging\GalaxySDK\GenTL\Win64\GxGVTL.cti\GxU3VTL.cti\GxUSBTL.cti

There are indeed 3 .cti files in the above folder, but I can't understand why they have all been lumped together under the 'Producer found' path. Could this have to do with why the camera can't be accessed?

So what happens when you call videoinput(), preview(), or getsnapshot()?

Thanks for the quick response. Using videoinput, the adaptor has one completion: pressing Tab, videoinput('gentl',). But the second field for the device ID has no completions, so Matlab is not picking up the camera. The error message is:

Error using videoinput (line 235)
There are no devices installed for the specified ADAPTORNAME.
See IMAQHWINFO

I already know from imaqhwinfo that gentl has no DeviceIDs recognised (the {1x0 cell} from above).

I solved my own problem...

Upgraded from R2017a to R2018a, opened up imaqtool just like before... and there it was. Can preview and acquire in 8-bit, and 10-bit preview works fine although the acquired images seem to be only black.
