Hi i wanna watch tv on my lapdock, this is what i have:
Motorola Lapdock 500 PRO Motorola ATRIX 2 MB865 AT&T Android 4.0.4 +root DVB-T Reciever for Android - CSL - mini DVB-T Stick (requirements - android 4.0 or high, dual core cpu (neon support) usb otg) Handmade Y. USB OTG cable (powered by wall adaptor)
After using chainfire diagnostic app for fix otg, I able to mount 2gb usb stick to phone, and can access files. means otg fix succesful and otg cable also works fine. Chainfire after check returns what is on screenshot

Then when i connect DVB-T Stick to phone by otg cable (else, if i connect it direct to microusb port - system not find device. possible just by otg cable) system popup message:

But after open Air Dtv (any other app which works with dvb stick simply cant find device) i get this message from app:

Reconnecting returns same error
