Hi,
I tried to connect my S8 to my PC using the TypeC <-> TypeC cable came with my Nexus 5x to the onboard Type C connector on my motherboard (Intel Z370). On the phone the battery icon shows the charging sign for a second then disappears, on the computer there aren't any indication of a connected device and it doesn't show up in the file explorer. If I use the Samsung cable and a normal USB A port everything is fine. If I connect my Nexus 5x with it's own cable to the TypeC port it's working fine. I used the Nexus 5x's charger and cable to charge my S8 since I bought it and there wasn't any problems.
Is there something I'm missing or the S8 is not USB 3.1 compatible?
Thanks,
Zsolti

An OTG cable is not for charging/connecting your device to a computer. Instead of usb micro to a male usb, it's micro to female usb, so you can plug in peripherals and flash drives etc. to your device.

When a normal USB is plugged in, the Nexus is in "slave" mode. Receives instructions.
When an OTG cable is plugged it allows it to be in "master" mode. Can give instructions.

There are basically 3 types of cables you can plug into the USB port of a Nexus 7:
1. A normal USB-to-microUSB cable, plugged into a computer or a USB charger. Either way it charges, and if it is hooked to a computer the N7 is in Client Mode and you can transfer files as well.
2. High-current chargers (like the one that comes with the Nexus 7). The data lines on these are shorted together; this tells the Nexus to accept higher current on the power lines for faster charging.
3. OTG cables have the normal 4 wires on the USB end - two for power, two for data - but on the microUSB end there is a fifth connection called USBID. Normally (as when using a normal 4-wire USB cable) the USBID pin is floating, i.e. not hooked to anything. On an OTG cable, the USBID pin is connected to the ground wire. This tells the N7 that an OTG device is plugged in, which causes it to do two things: it reverses the current on the power lines - because it needs to power whatever you have plugged into the OTG cable, like a USB card reader or keyboard - and it switches the USB interface from Client Mode (which it uses when it is plugged into a computer, because in that instance the N7 is a peripheral device) to Host Mode (because in that instance the OTG device is the peripheral and the N7 is the 'computer').
There is one other option for charging: the pogo pins on the side. (The 4 pins are 5V, stereo left, stereo right, and ground.) Providing power to the pogo pins (as when it is put in a dock) tells the N7 to accept high current on the pogo pins. Momentarily connecting 5V to the right stereo channel tells the N7 that external speakers are connected and it starts driving audio out the two center pogo pins. When this is happening the charging takes place through the dock, the USB connector can be used with a data cable or an OTG device, but no charging takes place through USB when the dock is connected. (An OTG device is still powered by the N7, but current never goes the other way.)

Dont forget a "y cable", which can charge and preform host mode (otg) at the same time, only at a slower charging rate. This is providing you are using a kernel that supports this function. "Otg+host mode charging"

Hey, i just received my usb 3 cable (my s5 came with usb2...) and i think i got a fake one...
I bought it from here: ebay.com/itm/291161252997?var=590311054317&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Now the problem is, when i plug cable in it USB options there is no "Media device (USB 3.0)" option... Which if i am not mistaken should appear?
I don't understand... 190 cables sold and no one is complaining... Maybe i am doing something wrong?
You might connect it to a USB 3.0 Port, are you sure that you connected it in 3.0 port?

Yes i am sure i connected to usb 3.0 port. I just found out that my external monitor connected via usb using same type cable as i ordered (but it's very short cable) and it is usb 3.0. Tried connecting with it and now i can see that option. So i guess that means i got fake cable...

Based from my experience, buying micro USB charging/data cable for Samsung is tricky since the wiring may not be the same as the normal USB cable. There should be 5 pins on the micro end, but sometimes there are just 4. But Samsung uses only 4 pins that might have been rewired. I'm not sure whether only Samsung does this or the same can be said of the other brands, but they may be the cause why there are microusb cables being sold that does only charging and no data function, and vice versa. And sometimes the pins may not be protruding out enough to make contact with the phone's charging pins.
I hope this helps.
You should try plugging in another USB 3.0 device such as a USB stick to determine whether the fault lies within your computer or the eBay cable!
I can connect my V20 to a Windows PC via USB cable, and transfer files back and forth. I had to pick something on a menu the first time I plugged in the phone.
However, if I plug a USB stick directly into the V20, it does not recognize it, or respond at all. My friend plugs the same USB stick into his V10 and an app pops up and shows the folders.
I'm using a micro-USB to USB-C adapter on the stick to plug into the V20. I know the adapter works, because I tested it when connecting to the PC.
I have searched settings for "USB" and it only comes up with USB tethering.
This is an AT&T stock phone, using the stock launcher. No root or anything.
Any idea how to get the USB recognized on the V20? Thanks.
it might be that the USB host function doesn't work with those adapters. have you tried plugging in a USBC to USB adapter and plugging a flash drive into that?

I've tried the same thing without success. My note 3 & 4 worked fine. I also had a Note 7 and Nexus 6P and it didn't work with those either.
has there been any advancement on this issue?
Did anyone find the answer to this? My V20 used to boot up a USB stick but just stopped working one day.
Whenever I plug my G5 Plus to my computer (Windows 10) the phone starts charging but I cannot see it as an external hard drive on my computer. When I slide down the notification's bar there's nothing there for me to choose from regarding usb functionality. I've tried out 4 different usb ports and the same happens all the time. Any thoughts?
Just "fixed" it. I was using a regular usb cable. When I plugged the usb cable that came with the G5 it worked. I plugged it back with a regular usb cable and the issue reappeared. Does anyone know what type of usb cable does the G5 plus come with so I can get more?
Hello everybody. Asking for help and suggestions. Maybe LENOVO representative take notice. Have secondhand yoga book. Resolved almost all problems but micro USB port. First of all, charging device died out. Find 30-watt charger with QC 3.0 and charge now working perfectly. Next tried to connect mouse, usb hub and usb dongle. Each time got DEVICE NOT RECOGNIZED message. Got error in device list.
But......tried to connect external HDD with noname HDD box and it connected. Connection may work to copy, install files or disk may disconnect randomly.
Tried system restore, tried to change drivers ( intel drivers for chipset not avaliable now) with no luck. Think problem is with low port current, but even small mouse and dongle make error and non-SSD HDD work 9 times out of 10. Have anybody experience problems with connecting devices to micro USB port?
Tried 3 different OTG cables and OTG micro USB to USB dongles. No luck.
Maybe the port is corrupted or desoldered

I did change it with the warranty I had. I had the same problem and did not want to fix by myself as the warranty was still active
