Build ID: 2016-04-27_16-24_dev_586b734

Android API:
Claims support: Yes
Classes found: Yes
Device detected: No

Rooted API:
Claims support: No
Device detected: N/A

Kernel:
Claims support: Yes
Device detected: No

Verdict:
OS support: No
3rd party apps: No

I don't know where you go from here.

Thanks. I haven't used this software myself and so am likewise unsure how to interpret the results. I had a look at the developer's forum:

http://forum.xda-developers.com/show....php?t=1493325

It's also rather cryptic. The results don't look uniformly bad. I presume the verdict is just a result of the more detailed categories above it. It may be a problem with the device or the cable. I guess a standard USB HID keyboard would be the least demanding device to try. I dare say others will also post and we can try to get a feel for what is going on.
