[Q] Can't get USB-OTG to work on MB860?
Hello! I'm using an Atrix MB860 with CM7-MROM, rooted and unlocked. I have a USB-female to micro-b-male USB-OTG cable (yes it is an OTG cable with pins 5 and 4 shorted or whatever), a powered USB hub where the red +5v line is coming from a 5v, 600mA power supply, not the usb cable, and 3 different USB OTG host controller apps.
My powered USB hub works just fine on both of my computers, so I know that its not the issue. But I can't get my Atrix, or at least the USB OTG apps I've tried, to recognize any device I plug into the hub, or even straight into the cable. I've tried 2 different wired keyboards, a wireless keyboard/mouse, an xbox 360 wireless controller receiver, and 4 different USB flash drives, and NOTHING works on the Atrix (but they all work on my PC through the same hub). I have tried restarting the USB OTG apps, I've tried pressing the 'refresh' button in them, I've tried restarting the entire phone with the USB OTG cable plugged in on bootup, but nothing works!
What am I doing wrong?! I know this phone supports USB OTG, I've seen videos of it working on youtube.
- Okay, my powered hub + otg cable combo is confirmed working just fine on my friend's Motorola Xoom tablet running stock Android 4.whatever firmware. It recognizes both my keyboard and my flash drive plugged into the hub, at the same time. But when I unplug it from the tablet and plug it into my Atrix phone, so that the keyboard/flash drive are plugged into the EXACT SAME ports on the hub, my Motorola Atrix does not recognize them at all.
What. The. Hell.
