Android adb会返回“找不到设备”错误

Question

When I plug my HTC Desire S phone into the PC (Win7) via USB, Device Manager shows a network adapter called "HTC Remote NDIS based Device".

Attempting a port mapping with adb, this happens:

7:22:09.68>"C:\Program Files\HTC\HTC Sync 3.0\adb" forward tcp:7777 tcp:7777
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
error: device not found

Do you have any advice?

Answer 1

Several responses mention "Select the "Unknown sources" checkbox; you find it in "Settings->Applications->Unknown sources."

Perhaps that was an option in a previous version of Android, but for me (using Android 4.4) there is no "Applications" sub-menu under "Settings". This appears to have moved to: "Settings" -> Security -> "Unknown sources"

Answer 2

Try to connect you device in Media Device (MTP) mode.

I have the same problem and after switching to MTP mode adb was found my device.

Answer 3

First check whether the device is attached or not with "adb devices" command (it is inside the platform-tools directory).

Just for information, to start with Android application development with a real device, you have to change some settings:

1. Select the "Unknown sources" checkbox; you find it in "Settings->Applications->Unknown sources."
2. Select the "USB Debugging" checkbox; you find it in "Settings->Applications->Development->USB Debugging."

Answer 4

First check if the device is connected; type the following command:

C:\Program Files\HTC\HTC Sync 3.0\adb devices

If the device gets listed, then perform your task; otherwise, there is a problem with the connection.

Answer 5

Tried to reboot your phone ? That worked for me once
