Hi guys!!
HTC Desire user here BUT I've a work colleague with the Galaxy Portal (Spica) which, for some reason, won't offer to mount the SD card to the PC when connected. It will chime and charge over USB so it knows it's been plugged in but no icon appears in the notification bar to allow you to mount the SD card as you'd expect to see with a stock Android phone.
It's on the 3 network in the UK running the Android version it came with (2.1)
Any suggestions??
I sometimes have this problem too.
I can fix it by going to:
Settings -> Applications -> Development -> USB Debugging
Turning it on/off makes the notification appear and enables USB file transfers

Not sure what fixed it, but the CM on G1 allowed me to mount my SD using my car stereo's USB (JVC KW-AVX820). Native G1 and none of the 3 USB modes on the Vibrant work. Any idea what file system feature did that?

Same here. My Genesis Coupe keeps showing either 'Media Connection Error' or 'No Media Connected'. It even rebooted my nav/stereo this morning and then froze it on the FM screen with no audio. Had to turn the car off, then back on for it to be fine. Not sure why the Vibrant would have issues like that.
Actually, with my G1, I hadn't got USB Mount notifications for awhile. Other rom's however worked fine. My wife's MyTouch works no problem, so I know it shouldn't be the car.
I don't know anything about car computer usb, but I'll share one experience I had working with a copier at work: USB running in a mode that simulates a USB thumb drive works. USB running in a mode that shows a micro SD card READER (as opposed to a single solid-state unremoveable drive) does not. That discrepancy could be responsible for what you are experiencing.
Make sure after you select mass storage you then mount the usb (its a two step process)
But also, it still might fail as I've noticed when you do this the device is actually mounted as well (oh that glorious 16gb of onboard space!) so the stereo might not have any idea of where it should be looking.
You need to go into settings and enable USB debugging
I think it's under settings application development
that didn't do it
Try disabling USB tethering
Sent from my HTC Dream using XDA App
Updated to froyo a little earlier. Went to try and set usb to mass storage in settings/about phone and there are no usb options there.
Anyone else got this problem? Or have I missed something?
No pulldown option to mount the usb either.
They are now in the wireless settings, for some reason.
Look under wireless and network --> Usb
Great, thanks guys
Hi
My problem is that when I connect my sm-n900v to my laptop no usb icon showing up in notification bar device only charge.
I removed the driver and install it again not working.
I disable usb debugging not working and enable it not working
anyone know how to fix this problem?
I'm having the same problem. This started only after lollipop update. Device charges, but laptop does not "see" usb connection. Nothing in system tray. Nothing in device manager. Current version Kies just installed, but doesn't see phone when connected. Restarted both laptop and device disconnected and connected.
SM-N900V Android 5.0
Windows 7
Don't have a clue how to fix this. Any ideas? Thanks!
Thought I'd post my update. While my original USB 3 data/charging cord seems to charge flawlessly & quickly when plugged into the correct 12v OE wall charging adaptors, there is apparently a problem with data transfer. I think the cord I'd OK, but its loose when inserted into the port on the device. If I hold it JUST so, it works fine. I suggest patient cord manipulation to determine if this might be the problem for others as well. Might be hardware repair time.

Hi
I found this solution and it's work now
With the device plugged in:
Dial ##366633#(##DMMODE#)
Disable DM Mode
Disable USB Debugging Mode (Menu> Settings> Developer Options)
If you don't see Developer Options, Enable them by going to Menu> Settings> About Device and Tap "Build Number" 7 times. This will enable Developer Options.
Allow Drivers to load completely. This can take up to 5 minutes.
Device should now appear in device manager as Samsung Mobile USB CDC Composite Device
Now..With the phone still plugged in, turn off and turn on (Restart the device )
Again allow the drivers to load.
you will see the usb icon showing up in your device..
:good::good:

i knew i wasnt crazy and i had a usb menu show up on connect...btw a temp fix to not showing up, download more shortcuts, open app click activities -> click settings -> USB computer connection(Settings$UsbSettingsActivity) and select MTP or USB 3.0. You will have to do this everytime you unplug,(or set a shortcut on homescreen to open setting panel)
Hi everyone,
My mother is the owner of a Huawei P8. She used to use the phone as a second hard disk but lately she touched something (and she does not remember what) and the phone is set to charge only when connected to the PC.
At the moment when the phone is connected the computer neither the computer or the phone seem to recognize each other. I went through almost all the settings but couldn't find ANYTHING on how to make the computer react to the phone. Moreover in the developer options of the phone USB debugging is greyed out, totally inaccessible.
If possible I would like NOT to have to root the phone or do strange installations. Online the only kind of answer I found was that I have to do a hard reset of the phone. Is it true?
Thank you for your help and patience.
Best regards,
Vanja A. Mariani C .
When you connect the P8 to the computer, it will appear in the notification bar a mention to the USB connection.
It has a blue USB icon and it shows "Photos", "Files" and "USB unit" (or somewhat like that). There is an small text there that states "if you don't select any mode, the device will only charge". Probably your mother put accidentally her finger over the "Files" option and this notification works like a On/Off switch .
If you want to use it as an USB drive, just put your finger over "USB unit". This mode is like plugging a pendrive to your computer (apps on SD
card will force close). Alternatively, you can put your finger over "files", and the SD card will mount in MTP mode (slower, but doesn't close the apps).
See my screenshot (it's in spanish, but you will quickly see what I mean).
Cheers.

If im correct the solution is:
Deactivate Developer options and then reactivate it again.
Then the USB debugging option should work again.
I'm having an issue getting Android Auto to launch in my Subaru Crosstrek 2018 model. It works when I use my Nexus 6p but not with the Essential phone. I've tried different cables and reinstalling Android Auto but no luck. Anybody else having issues with Android Auto in their car with the Essential phone?
I had major problems getting Android Auto to work with my Essential phone.
At first, I kept getting the red screen of death (something about "do this when the car is stopped and the brake is on"...of course the car was stopped and the brake was on...). The next day (after a phone update), I tried again and could get past that screen. But then it wouldn't connect.
Turns out you have to scroll down the notifications and change the connect mode from USB charge to MTP manually. Once you do that, it quickly connects. Why the phone can't automatically do that for you...I don't know. But I've done this repeatedly now and each time it connects once you change to MTP mode.
(I also have USB debugging on--don't know if that's important as well).

Android Auto doesn't kick-in on my '20 Subaru Outback (works on my wife's '19 Nissan Rogue).
Can you specify how to get to this setting. I'm unable to find it...
Thanks

For the current connection, expand the "usb charging" notification, and it will give you a prompt to the available options - just select what you need. To change the default USB connection behaviour, go to Settings - System - Developer options - Default USB configuration, and select an appropriate connection mode.

Funny there is no USB charging notification on the top, but in Default USB configuration should it be on File Transfer? Thanks!
I've never had a problem with android auto on mine, though I think I probably did change the default connection mode to file transfer a long time ago (before I had a vehicle with android auto).
You can also try a USB hub. These resolved the problem:
AmazonBasics 4 Port USB to USB 3.0 Hub with 5V/2.5A power adapter
ASIN B00DQFGH80
TP-Link | 4 - Port USB 3.0 Hub | Slim & Foldable Cord Design | Compact Travel Size with Charging Ports | Universal Compatibility - USB Flash Drive, Notebook, MacBook, PC, Chromebook and More (UH400)
ASIN B012B6YQY6
