Android Studio 3.5.2 找不到 USB 连接的设备（但通过 adb 终端找到）

Question

The title pretty much says it all: I'm working on an Android Studio (3.5.2) project on my Windows 7 64-bit running laptop, I connect my Samsung J7 (2016) to the laptop through the original Samsung cable but Android Studio simply can't see the device. If I try to do the same on my desktop computer (same Android Studio version but on a Windows 10 64-bit OS) everything works just fine.

Here comes the funny thing: the "adb devices" command shows the device (and I'm 100% sure it's my smartphone since it's the only device connected). The Android Studio toolbar keeps showing "No devices" anyway.

I've spent 3 hours on this and couldn't find a solution. I already tried every suggested solution around the web (stackoverflow.com included), but I achieved nothing:

• Disabling/Enabling USB Debug function in the Developer Settings of my smartphone (including revoking USB debugging authorizations)
• Running Android Studio as admin (sometimes it solves strange stuff...)
• Trying to USB connect through PdaNet+
• Android Studio built-in troubleshooting service (re-scanning for devices actually makes me see my smartphone but it's treating it as if it can't be used as a debugging device; anyway the smartphone-computer connection is just fine: I can browse my files and all. Killing and restarting the ADB server does nothing)
• Tried connecting both as PTP and MTP
• Tried both the Google USB Drivers and the Windows Update drivers (those the computer gets when you first connect the device)

Thanks in advance:)
