The string returned from IMFAttributes::GetString with MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_SYMBOLIC_LINK or MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_AUDCAP_SYMBOLIC_LINK this is device interface string which we can use as input to CM_Get_Device_Interface_PropertyW. The only piece of data I have is it's "symbolic link" (in my case, this string: \\?\usb#vid_04b4&pid_8888&mi_00#9&4fe28be&0&0000#)Īll 3 are USB devices, all 3 are listed when calling MFEnumDeviceSources but their "symbolic link" doesn't resolve into a hardware device.
Is there a way to do so? I can't find how to get "device" info from that activation object. What I'm looking for is to get that information from a given IMFActivate object. That info is available through Windows' Unified device property model APIs. semi-useful, like "Location 0 (Internal High Definition Audio Bus)" or "PCI bus 9, device 0, function 0".human-readable, like "on NVIDIA GeForce GTX 1080".If you're still experiencing the problem, call us at 1-87.When going to Windows' "Device manager" and clicking on (almost) any device in the list one piece of information in the "General" tab is called "Location".Make sure the outlet works with another device, like a lamp.
Restart the devices you are trying to connect to the Hotspot.
Make sure it's connected to the right Wi-Fi network. If they work are expected, the hotspot is not the problem.Ĭlose or disable any programs running in the background and clear the browser cache & history. Try accessing a different website or app. If not, the problem is not with the hotspot. Test to see if it can successfully connect to other Wi-Fi networks. We can't support game systems, TVs, or non-T-Mobile phones or tablets.Ĭheck that all timeout, power saving, or hibernate features are off. Try connecting a different computer or T-Mobile device to the hotspot. Make sure it is within 15 feet of the hotspot. We want you connected, and Mobile Hotspot should give you Wi-Fi wherever you go.
