MTP Issues - General Questions and Answers

I have been seamlessly transferring files from my LG G2 to my Win 7, & Win 10 PC's for months. All of a sudden neither PC will recognize the handset. I know the more descriptive I am, the easier to troubleshoot, but I have not changed anything on any of the devices that I would suspect to cause this issue. It seems to be an issue with the handset since the issue is with two computers. Any thoughts? Thanks!

[Q] Phone connects to PC but can't see any files

So here is a very interesting question. Or problem perhaps more so. I have the VZ GS3 with the newest PA build 9-17-12 and when I connect my phone to the computer to use it as a mass storage device, I can see the directories, but there are no files shown inside. Also there are many many unnamed directories that show up as well on the SD card portion of the Device. It also seems to show it as a "Portable Media Device" perhaps anyone has some ideas about this one?
Just an FYI, I had this problem on several computers I've tested Windows 7 and Windows XP. Also I had this issue when it was on Previous Roms, ir does not seem to be specific to the PA build I'm on now.
Are you using the original USB cable that came with the phone? I had similar issues using a different cable that I had laying around but as soon as I used the cable that came with the phone all issues were fixed.
Honestly, I didn't even think about that. I'll try that as soon as I get home. (At work now). Thanks very much for the advice.

Windows 10 not finding nexus 5

I have not been able to connect the phone since the windows 10 upgrade.It never finds the devise?
Has anyone else seen this and if so is there a fix ?
Thanks
I actually did have some issues initially. I believe i went in and disabled, then reenabled MTP mode on the N5 while it was plugged into the computer, at which point it was able to see the phone and files correctly. This was while the phone was running the latest official stock. As a side note, I've since put the 3rd developer preview of 6.0 on, and had no troubles at all with Windows seeing the files. I have heard that 10 is still having issues with certain portable memory systems (for example, Nikon camera's aren't functioning correctly; they show up, but have no files listed at all when plugged in via a usb cable). I've only heard of microsoft saying that they are "aware of the problem" thus far.

PSA: Mobile Hotspots not working with Windows 8+ Systems (Broadcom drivers?)

Hey all. I wanted to make a little "Public Service Announcement" regarding an issue that I have had for quite some time and finally solved tonight. I'm hoping it will help someone else because the symptoms of the issue were very strange and an answer was not forthcoming through standard searching.
I have an HTC M8 (Verizon) and I have been having problems with my "Mobile Hotspot" feature for a while. I thought the issue happened after my first upgrade to Marshmallow, but as it turns out the issue was with my Windows 10 PCs (read on...).
Basically, I was able to connect to my phone's Wifi "Mobile Hotspot" without any problems from an iPad tablet or from my wife's Samsung phone. However, when I tried to connect from my Windows 10 PC I had very strange symptoms.
As per my profession, I consider myself somewhat an expert on Windows and networking in general (not "the expert" but "an expert" ). What was so strange about this issue was that the Windows 10 PCs would see the SSID from my phone without a problem. they would connect after providing the encryption key, and they would even get an IP address from the phone's DHCP server. But, after that, they failed to communicate on the network at all. Not even able to ping the phone (default gateway).
I won't go into the details of all my troubleshooting steps (everything from reboots to wireshark analysis), but honestly nothing worked. I determined it must be an issue with Windows 10 after having two different Windows 10 laptops fail to connect properly. I remembered that I didn't have these issues when my system was running Windows 7.
Even armed with this information I was unable to research to any suitable solution online, when I came across a post somewhere that hinted at a similar connectivity issue. The poster seemed to indicate that the Microsoft drivers caused some issues with their devices that was resolved using older vendor drivers.
Both my Windows 10 laptops in questions are quite old. They were never meant to run anything past Windows Vista/7. Because of this, the vendors didn't really offer complete driver packages for these systems for Windows 10. But, during the Windows 10 installation, the OS detected all the hardware in these laptops automatically and, until today the provided Microsoft drivers seemed totally functional.
I hunted down the latest drivers I could find from the vendors (HP/Dell) and using device manager forced the installation of those driver packages. Immediately upon update to those drivers I was able to connect 100% properly to the Mobile Hotspot and access the Internet.
As it turns out, it seems both laptops had Broadcom based cards - so I suspect the issue may be specifically with Microsoft's Broadcom driver.
Hopefully this comes up in a search for the next person having similar issues.

Galaxy S7 not detected by PC (Windows 10, latest Creator's Update)

Hi,
My girlfriend has some issues with her W10 PC. She's on the normal builds (not Insider), latest updates.
The PC is able to read other USB sticks, so the ports are not broken. The phone is identified by the PC, but it only works as a charger. When the state is changed to MTP, nothing appears in My Computer.
I tried to hook it to my W7 work laptop and everything was fine. I have to add that no drivers for the phone were installed on my part.
Any idea if this is a known glitch with W10? I'm on the Skip Ahead builds, so I don't think it's relevant if I check it on my personal laptop.
Thing is, the phone was seen by the PC just fine until a while ago (I don't know what ago means, girls have weird time perception when it comes to technology).
Any hints on what can I do to fix this?
Thanks!
I use Windows 10 Pro with latest updates and Windows and Odin see the phone but not adb for some reason.

Laptop does not see Pixel 2 unless connected prior to start up, what am I missing?

OK this has been fixed somewhere I am sure but I can't seem to find the answer.
Laptop (higher end gaming laptop built by Sager (use it for Auto Cad)
Windows 10 currently updated till April 2018
Happens with all phones (2 different Pixel 2's and 2 Moto X4s)
Happens on both the USB 3 and 2 ports
Most current USB Drivers from Android studio
ONLY sees the devices (will always charge) if the device is plugged in prior to Windows starting
*note - Switching devices (Moto to Pixel or Pixel to Moto) after computer sees one does not work unless you restart Windows
This seems like such a stupid thing and I have been working around it for a while now but would be nice to resolve it once and for all.
I have tried purging and removing all extra usb drivers, reinstalling the usb drivers, removed all the other usb devices and the files that go along with to avoid any conflicts. Only have this issue with the androids recently. Not sure what has happened other then the use of USB 3 since the Pixel came out but I didn't have this issue with the Nexus 5x's I had before.
Hope someone has had the same issue and found fix and is willing to share the cure.
If not then I will just continue along as I have been and quit complaining, it could be worse like some have had.
Thanks
Solved : Found there was an issue with the usb composite driver that got messed with with the power saving features at some point. restored the default startup features and uninstalled the usb composite device in device manager then re-started the laptop allowing windows to reinstall the drivers for the USB hub. so far so good. Such a rare issue on the web with the phones but yet common with other usb devices using non microsoft drivers.
