adb devices does not list the TC75

Hi team,

I need to fastboot (11-04) a TC75,

I put the device into USB debugging mode and connect to PC.

The driver recognizes the device as a TC75 however nothing shows in adb devices.

Any ideas?

regards,

Daniel

Daniel, I assume the usb

Daniel, I assume the usb debugging has been enabled on the 75 and you have accepted the security request displayed on the device when the PC tries to connect?  The ADT tools themselves need to be updated in some cases, you my try to update your Android Build tools in the SDK manager as well.

I have tried uninstalling and

I have tried uninstalling and re-installing various drivers.

The current situation is that the TC55 can be seen in ADB devices, however the TC75 does not.   I do have USB debugging on however I am not seeing the security request appear on the device.

You can revoke any previous

You can revoke any previous debugging authorization Developer Options - Revoke USB debugging authorization. 

When you disconnect and reconnect the device should prompt you with the computer's RSA key for authorization.

Hi Daniel,have you tried with

Hi Daniel,

have you tried with a different TC75's USB cable (not the charging one :-) ) or on a different computer?

Which OS are you using? can you see the device connected to the USB port in the device peripherals?

I have run into issues with

I have run into issues with both ADB and FASTBOOT executables where the most recent ones behave in this and other ways.  Going to older versions or the version of executable seem to resolve this issue.  For a while I setup my environment to always point to these older versions until I got the Android Creemore devices which do not play nice with the older versions...so for now I have to manage this differently.
