Hi and hoping for illumination about connections as I now have a Gordion knot of USB and OTG cables on my dining room table.

Issue - tablet and DSLR Dashboard not recognizing the Canon 5D.
Pic attached of the tablet screen on opening the app. Tapping 'search for USB camera' does nothing.

I am trying to do a wired connection from the Canon 5D Mark III to a 7inch Dragon Touch DT744B tablet, running Android 4.0.4, purchased off Amazon. The description of this tablet states it supports USB-OTG and it came with an OTG cable. I have also installed OpenCV Manager 2.16, per the prompt on installing DSLR Dashboard. I am attaching that OTG cable from the tablet to the mini-USB port on the Canon.

The tablet is fairly inexpensive which is why I chose it, as its sole use will be for DSLR Dashboard. I cannot find any online documentation about this unit and I've emailed the manufacturer just to confirm it is OTG compliant. Must it also state USB host compliant, or is that the same thing as USG-OTG compliant? I've read every posting on this forum, and tried to interpret the postings.

Any thoughts on why there is no connection?
I'm hoping I didn't pop for a single-useage tablet and make the wrong decision.
Choosing to go wired vs wireless as I don't want to deal with wireless issues in heavy wireless usage regions, and I don't want something with yet another battery.

I dont know this tablet, and i can't judge how crippled its Android Version is. Most ROMs of Android compiled for these cheap tablets without OTAs are (if at all) only OTG Mass Storage compliant.

From a distance and with a bit of knowledge on my back, I would say chances are low that you have full OTG support on this tablet, and not only because it is dubbed "Dragon Touch"

But you could always spend another 45$ and use a TP Link Router to control the camera wirelessly over DSLRD before you write off the tablet and buy yet another one

Cheers.

I tried the application you suggested - usbhostdiagnostics - and bam, it fixed whatever was goofy with my tablet and everything works. I didi't put an exclamation point there, but I am thrilled. YOU deserve a big wet kiss. Where are you? C'mere…I'm gonna KISS YOU!
