I'm trying to develop applications that talk to USB devices, but nothing works. I installed a USB Host Diagnostics app, and it tells me that there's no OS support for device detection on the Galaxy Nexus or the Nexus 10. I'm running Android 4.2 on both.
I tried the AdbTest sample application, but that doesn't respond when I connect the devices together. I tried updating the files in
/system/etc/permissions as discussed here, but that doesn't do anything.
Can anyone get USB device detection to work on these devices? Thanks!
