could be due to USB cable damaged internally or try options in My Android Solutions link below
Or try to install latest USB Samsung drivers on your PC.

[Q] Help me!Is it dead???

Hi!Help me! Is myOB dead?How to fix this??? You can see problem on the youtube video -- http://youtu.be/F4HCOqoeaC4
THANK U!!!
Install LG drivers and try! Will work
Hi Emil, first check some simple steps. Be sure that you have the latest driver and the cable is not broken.
Remove battery and before connect the OB whait a minute. Try to connect to the USB port behind your PC not in the frontal port (If you have a desktop PC).
If you’re no longer able to activate in download mode try reconnect your battery and make a forced restart by pressing VOL-UP+SWICTH ON, then retry to reconnect in downloade mode (VOL-DOWN+cable connect)
I hope you’ll resolve…good luck!

Service Center is the only option left. If Emergency Recovery doesn't work.

Installed CM13 and getting BSOD when connected to PC

Hello everyone,
Yesterday I installed CM13 and it is very good. I haven't found any problem as of now in my phone but I am getting BSOD everytime when I connect the mobile to my PC through USB. I tried everything from changing the cord to changing the usb port, even uninstalled LG drivers but still getting BSOD.
Can anyone help me to understand and solve this. Right now my only option is to take SD card out and connect it using Card Reader. Phone is working smoothly. No issues so far. Its just this problem is bugging me. Appreciate if you guys can help me out. Thank You.
Okay so I am getting BSOD only when I am enabling the USB Debugging. By disabling USB Debugging I am able to connect the phone to PC but it is only in the charging mode. I am not able to access any files. It is showing blank. So what should I do now?

1st: The USB Debugging problem only occurs on Windows, Linux distros are fine
2nd:Just pull out the status bar and click on the charging one. You'll be given 3 options: charging, MTP and PTP. (Sorry if I misspelled the names, it's been a long time since I've done this)

Thank You. I can now access the files.
Yes I am on Windows 10. USB Debugging BSOD is still an issue. So is it okay to keep USB debugging off? I always keep that option enabled cause I thought its an important option if you happen to brick the device. So what is the solution? is this happening for everyone who are on custom rom?
Thanks once again.

It's okay to leave it off. If you happen to brick your device, it won't boot, meaning no USB debugging.

Someone post answer in cm13 thread - some issues with drivers from LG with cm roms compilations or something like that. Just UNINSTAL driver from PC and u good to go connect l90 via MTP
You mast UNINSTALL driver from PC and reboot PC.
Then install this drivers and reboot PC:

L90 with 5.0.2 stok ROM or CM13 works correctly.

I see, have you tried clearing the cache of MTP Host from Apps in the System Settings. Also try disabling USB Debugging.
I have this same issue using LOS 15.1. The solution is to go into Developer Settings and enable MTP using the 'Select USB Configuration' option. Then when you plug in via cable you will get the notification as normal. The problem is you have to do this every reboot, otherwise it's the same situation all over again. No Notification on plugging in and no way for your PC to see the device as it defaults to Charging mode.
I have "select USB conf" set as default (charging) and never had this issue. My PC sees the device even if I don't change the mode, I just don't see any files then. What drivers are you using?

I just installed the Official Oneplus drivers but it didn't help. I didn't think it would. The generic Windows 10 drivers were working fine with LOS 14.1. As you said, the PC does see the phone just fine, but not files until MTP is enabled.
It's the lack of a Notification when plugging in that's the problem. Without the Notification i can't switch from Charging to MTP mode. I've tried all Notification levels too. The only way to get the Notification to appear is to use the MTP setting in Dev Options, and then it works.. until next reboot.
Edit: Enabling 'USB Debugging' seems to be a working fix currently!

I spoke too soon about USB Debugging working. It doesn't help across reboots. Gonna Clean Install now. Hope you find a fix.
Clean install didn't help me. Just Google 'Oreo no mtp' to see how common this is.
I have a Nexus 5X on Oreo that doesn't have this problem. Other N5X owners do have it. It's totally random.
Good news everyone...
A fix is coming:

At least for LOS 15.1 and any other ROMs based upon it.
