I give this answer a lot: Try another cable. One of the data connections has broken, which lets you still charge but breaks the USB I/O.

[Q] cannot connect to bootloader

hi. i'm having problem in connecting my device in bootloader..
i used to be able to connect with PDAnet in bootloader without any problem, but now all i have is "connecting to your phone". I've downloaded the USB driver package from the sdk but still no luck..
any idea ?
*yes i search the XDA forum and try following the guides but i still have no luck*
have you tried the connection on another computer?
sometimes the computer USB ports tends to go crazy and wont work with the device no matter what
there's an utility (forgot the name) that lets you delete all the bugged USB associations in the PC
if you can find that, then you can try it as well

i have the exact problem like u. when i connect my note 10.1 to my pc via usb, my pc wont detect my note storage even though i set it at MTP. the only thing that come out is scanner and camera wizard. please someone help
If I remember correctly when I connected my GNote10 to my laptop all I could see was the sdcard not the external card. Well it could seevthe external sdcard but not what was on it. I put it down to the fact I run Linux and the drivers for the GNote10 may be different. However now I use WiFi File Explorer Pro and Bluetooth for transfering files as it seems easier for me.
There is a app to fix this on SSamsung apps store search for kies it will be there

Erica, unfortunately, this app does not install. If you're talking about Kies Saver WiFi.
Try connecting it to another Windows computer to see if it is detected to rule out whether or not it is a specific computer's issue or your tablet.
If it's just that computer then only thing I can think of is if you go to the Device Manager in windows and look under the "Universal Serial Bus controllers" Host controllers and see if any have an exclamation mark.
From there you can try uninstalling that device and then either reconnect or reboot your computer and reconnect and see if it now detects it.
Could try this program on your computer to remove usb entries.search google for usbdview program for your pc.it will show all conmected usb devices remove old android conmections
Good luck this helped me before

I solved the issue like THIS:
Downloaded KIES
ran " connectionproblems" function of KIES (drivers will be newly installed)
Restart PC
Connect
And , voila, MTP works flawless ...........
FIXED
I pluged it in like you had and just got the un-ending "Connecting" in Kies. It showed the device ID (GT-N8013) in the connected device tab however it would never fully connect.
So what I did was while it was trying to connect in Kies I changed the connection type in the Note from MTP (Media device) to PTP (Camera). I got a few error messages in Kies saying that it can't connect to the device because the device was in the wrong mode. After I cleared those error messages and Kies stopped trying to connect. I than set the USB PC connection back to MTP and let Kies do its thing and no problemo there it was.
Hope this helps some of you! Have fun! Also the kick in the pants is that there is no firmware update available still stuck at 4.1.2. I was hoping 4.2 would be available.
same problem as OP
I have the same problem as OP, my PC just doesn't recognize that a device is plugged in. The Samsung note 10.1 beeps and charges but that's it, my PC is non the wiser to anything changing at all.
I'm running Windows 7 64bit and I've tried it on my brothers PC, same OS, and my dads which is 32bit. re-installed windows, fully updated Samsung and windows, Kies just says "plug in a device"
USBDeview doesn't recognize anything.
Nothing in device manager.
I've contacted Samsung after searching high and low on Google for an answer and they diagnosed it as faulty.
Repair center says it's working fine and sent it me back.
There must be something I'm missing on the tablet, could it be a faulty USB cable? I have really run out of options.
because its rooted
wont work because its rooted i even tryed voodoo root keeper and samsung wont let me update becasue its rooted .. kinda stuck. cant even connect computer to install custom rom

I don't know if this is the case with you, but I experience connection problems very often, in particular with OTG. Connection seems to be reliable immediately after reboot but after a (short? longer?) while it stops and won't work anymore.
My guess is that a driver is not correctly reset when the tablet resumes from sleep.
It might be a problem introduced with the latest OTA.
Same here bro.. I tested to another PC but still not recognize.. maybe from the note?
Please everyone.. help help help

Fixed it with a £2 USB cable off eBay. If you have nothing but the tablet charging try a new cable. Worked for me after sending it to Samsung for repairs twice.

Try to turn on USB Debugging in Developer Setting. I'm using N8013 and that method works for me
My Note 10.1 (2014) wasn't being recognized in My Computer by the laptop running Win7, so I found the tablet in the Device Manager, double-clicked on it there, and downloaded the drivers. Loaded up flawlessly after that.

Since you reformatted your pc, did you reinstall all the motherboard drivers? Sounds like the usb drivers could be missing.
