DSLR Controller/Remote Release non funzionanti su Mediacom 860S2

Ho provato ad installare queste due app:

Remote Release
https://play.google.com/store/apps/d....remoterelease

DSLR Controller
https://play.google.com/store/apps/d...dslrcontroller

Sul Play vengono considerate compatibili con l'860S2 ma in pratica una volta connessa la dslr (nel mio caso una Canon 550D) ad un cavo usb (ne ho provati 2) e al cavo otg contenuto nella confezione del tablet le app non funzionano. Il tablet è rootato e con la diagnostica usb il tablet vede la fotocamera, il tablet ha tutte le caratteristiche che sono necessarie per far funzionare le app ma purtroppo non vanno. Idee?

Ho provato a cercare qualche info, su xda c'è il 3d ufficiale:

[Android 2.3.1/3.x/4.x][27.09.2012] DSLR Controller v0.96.0 BETA [USB HOST REQUIRED] - Page 117 - xda-developers

Hi all.
I got recently released 7" Huawei Mediapad, also known as T-Mobile Springboard.
I have the same issue, as described in some posts above: couldn't connect tablet with camera (500D, 550D) (camera: "BUSY" on screen message for a couple of seconds, and then works in its normal mode; app: "no compatible device....". I have already tried different firmwares such as Honeycomb, Honeycomb rooted, ICS beta not rooted - the result is the same. I have also tried to use additional power supply (Y-cable) - no result. At the same time USB sticks, mouses, keyboards work perfectly. Has anyone know how to solve the problem, or maybe someone have had no problem with connection of the same device?

Various devices are known to have this problem. It appears to be a kernel issue stopping non-kernel software to use the USB (sticks mice and keyboards are handled by the kernel directly), but I'm not completely sure, as I've not had one in my hands to personally test with.
