Hi,

When entering recovery mode on the Nexus 10 (Android 4.4.3), when I connect the tablet up the a computer it does not detect a USB device. This is not the usual driver related issue - nothing shows up in device manager - it is as though the USB cable isn't even connected. The usual sound from Windows when you connect a device does not sound.

I can connect fine when the Nexus 10 is booted, and I can call "adb reboot recovery" and the tablet reboots to recovery, but then there is no USB connection.

To reiterate - there are no driver issues as I'm not even getting as far as loading a driver! I've tried two different computers (Windows 8.1 and Windows 7) and two different USB cables.

Anyone seen this before? Why is USB disabled when in recovery?

Thanks,

Gary.

Figured this out thanks - turns out "adb reboot recovery" doesn't put the device into a state of waiting for a sideload - you have to do a further press of POWER+VolUp to bring up the menu then select sideload via ADB - the USB then kicks in! Doh.
