The text is to repeat, concise look at the bold word is good.
The title has a semantic error, and until the problem is discovered, it is not the Chrome browser that checks that the device is unavailable but does not check the device. But before the problem is found, this is the way to Baidu.
chrome://inspect/#devices, check the equipment, has been not checked, really anxious. And then gave up n times, because there are other reasons, today only to find a colleague's computer to try, he can!!! I tried it many times. Get your own computer again, or not to!!!!!!!!!!!!!!!
His cell phone and my test phone are all Huawei's phones. Faint to find, will have to drive what (with colleague's computer, looks like see Install drive). As a result, the use of 360 mobile phone assistant, the connection is prompted to install the driver, the driver is produced by the manufacturer, can be used.
Knot: When the Chrome browser checks that the device is not found, check to see if the phone driver is installed.
Chrome browser Check device is not available (chrome://inspect/#devices)
