[Q] Can't mount USB storage/SD card in OSX

I am having a huge problem mounting my Epic 4G to my Mac. When I select Mount USB, nothing happens. I have read several posts about Galaxy S phones having the same problem, they all say to have USB Debugging turned on, but mine is on and still can't mount.
Also, another huge problem. I connect my phone, then I use adb to access the sd card, but I can only use adb for a short period of time, then it disconnects itself, then I try to run adb again but it does not recognize it. I have to unplug the phone, then plug it again.
Does anybody have any idea why this is happening or how to fix it?
Note: I can do everything perfectly fine with my Sprint Hero
Thanks

I've successfully mounted my SD card on OSX. I have debugging turned off. If it won't mount, try a different slot, if that doesn't work, try rebooting the phone. It will work.

Dude, welcome to the club. Since i got my phone i have not successfully been able to have it read on my Mac Mini. Tried different cables and different ports. Some say get a powered USB hub but i'm not in the mood to clutter my puny desk space.
For now i use an app called Websharing to transfer stuff via WiFi. It's a pain sometimes but that's how i get by for now.

I don't have any problem with 10.5 or .6
I can use either regular or debug. Sometimes rebooting the phone and/or the computer helps. It could be a crappy cable. I don't think the supplied one is very good. The one I use with no problems is the overpriced 3 footer that the corporate sprint stores have. I think the cables that came with the epic, moment, and evo were el cheapo. I had a problem that you are describing with a stock supplied cable. I figured out that the micro usb end wasn't making solid contact with the phone. If I would move the cable, it would disconnect. Changing to a real micro usb cable helped me. It could be the usb port is flaky or the usb plug is intermittent. If you are using vmware fusion or bootcamp or dual boot, see if it drops connection in a different os.

No luck under Windows7 (running with Parallels Desktop) either. I'll try buying a new USB cable and see if that works ... Will try Websharing too.
Thanks

I am able to see and access the SD card at work after installing Samsumg USB Drivers under Windows XP, however I am not able to use adb to access the phone ... ahh, this is driving me crazy, I need to root the phone and install a custom rom ... >_<

Did you put your phone into debug mode?
I found that trying different USB slots on the PC, it will eventually work. When you plug it in the first time, it will install some needed drivers ABD etc, if you unplug the phone and plug it back into the same USB slot, it will install the last remaining drivers and you should now be able to see the phone.
Samsungs drivers are flaky at best. It took me a good hour to get it working for me so I could root my phone.

That worked, turning on USB debugging and switching to another USB slot. But, this is at work under WinXP. Now I need to make it work under OSX at home.
I'll try Ubuntu when I get home and see if that works...

temporary fix
This topic has been discussed at another tread.... but anyway, The Macs (current generation only) do not give you enough energy at the USB to power the phone into connecting the memory card. Nor even enough to recognize the phone for more than a few seconds. You can get around it, temporarily, by connecting through a powered USB port. Tetheris still doen's work, but at least you can mount your sd card. It's a software issue... if you're running Windows on the mac machine, it'll connect and mount fine. So, ask Mac for a fix.

Okay so I am running windows 7 64bit and have the drivers for my phone and have read many threads and done everything I have read to the T its getting really frustrating and I am so annoyed I need help I never had this much problem with my Droid and I can't clockworkdmod recovery to work either I am rooted and have tried flashing it even done it twice in a row but nothing has worked to get it on there so I wanna try the Odin approach but I need to connect it to my comp first
Thank you for any help and I hope you guys can suggest a solution that will make this my favorite device

What is the error message you get?

may or may not help , but i was going crazy the other day because my windows 7 wouldnt read mine either. then i realized i was using the cable from my droid x . it fit , and it charged it , but for whatever reason would not relay data.
Make sure its the one for that phone . not for another or one from walmart. helped me at least .

What exactly is going on when you plug in your phone?
You need to odin or redbend to install the hacked recovery for clockwork to work.

on the computer it says all the drivers are installed but when i connect the usb it says that no device is attached and its the cable that came with the box now something i just thought of is this is my third fascinate from verizon i was having issues with the hearing people and finally got one that worked and i connected and rooted both of those devices on this comp could it be that it wont read this one because it wants to read one of the previous devices if so how would i go about fixing that...thanks for all your help guy i really appreciate it i feel like a noob again coming from my flash happy days with my droid...and i wasn't trying to be sarcastic about the cord cause i thought of that too i just reread this and wanted to make sure i am showing gratitude and not seeming like an a**hole so thank u

i figured it out
i was using the same cable from my old fascinate with my new one and it wasnt detecting it on the comp so i got a usb from another on used it and worked like a champ i got clockwork woot woot thank u all

I am having a similar issue suddenly. My original cable began having intermittant connection problems while charging right after I spent 3 days charging my phone from my laptop due to a massive power outage. I recalibrated my battery stats but the physical connection from the cable is flaky during charging and now during data too. My laptop sees it as drive e but it wont let me access it, it tells me to insert a disk into drive e, however pdanet works fine. I did perform the hack to reprogram the 3g hotspot app to bypass the dun setting prior to this happening. Did qpst change something else or did mess something up? Any help is greatly appreciated.
Update: The intermittant connection from the cable seems to have corrupted the USB mass storage driver. Had to uninstall/reinstall it & everything worked. BTW the vzw store replaced my cable with a Motorola micro-usb and it works great; the plug end is about 1mm longer and it fits in the socket much better.

usb connection f***ed

Hi guys!
My device doesn't connect to my PC anymore, can only charge. The PC gives me a USB error and that's that. No more flashing! aaaargh....
As it still charges I suspect a software error, indeed hope for it. Any ideas?
Cheers

I have the same issue m8. Have done for several weeks now. No idea whats wrong. I was hoping to flash magdlr via sdcard and hope that would sort it out, but can't. I am also having other issues now too, e.g: excessive battery drain within winmo. When you turn screen off in winmo, it comes straight back on. Poor reception now (with any radio) was working fine before.
Android is now suffering too, poor battery drain(more than normal) poor signal.
Seg

Too bad. None of the other issues with me, though. Tried reflashing from sd, successfully, but no effect on USB, same for bootloader.

you need to give us more info on problem, what error do you get?, does xp try to install usb drivers when you plug in your phone?
Have you tried uninstalling and reinstalling your USB drivers / use another PC, cable etc?

Hi
Tried 2 PCs, a Win7 and Ubuntu. Ubuntu just doesn't see anything at all, W7 says a broken device is connected and refuses to proceed. Will do one more experiment and report back later. Thx for your interest

doesn't sound good to be honest. You could try flashing your ROM using your SD card though in the hope it is a ROM problem.

Sounds like a hardware problem to me. Have you tried a different usb cord? If that isn't the problem I'd make sure there aren't any damages prints in the phone's usb port.
Those are the most likely, it's rare that an internal hardware problem would only break part of the usb port

Hello at last some one I can help.......Maybe
I had the same problem, Mine also kept on trying to put me in car kit mode and turning loude speaker on. I think the problem started when I sat on my phone while it was charging. It some how shorted the USB in side the phone and I had to get it repaired under warranty. But.... if you havent got the same car kit problem try really blowing inside the USB normally one of those air cans ive heard has done the trick.
Cheers

Hi guys
As stated earlier I reflashed off sd, still charge only. Will try one more thing with the W7 PC. Oh, well, no NAND for me...

If you've updated your antivirus or flashed a new ROM, you may need to uninstall your antivirus, connect via usb, and see if your phone is detected by your PC and WMDC. Then, reinstall your antivirus.

Yes the antivirus thing kind of worked.. and btw go for ur stock rom...

have you considered the usb cable. it could be malfunctioning ! try another usb cable. blackberry's usb cable should work just fine.

Yeah, will have to try cable first, then stock ROM, possibly.

So it was the cable! Whew!

Can't mount phone as drive after installing CELB 4.1 Froyo

I installed 4.1 today and when I plug the phone in to the computer it doesn't give me the option to mount it.
The computer finds the phone but will not read from it.

Are you using a generic usb cable or the one that came with your Eris.
When I use a generic usb cable, 95% of the time I can see the phone install but it is completely unaccessible as a drive. This happens with every rom including the htc stock 2.1

you really should post rom related issues in the rom thread

I've never had a problem mounting my phone with my monoprice or ebay usb cables. I was about to flash celbfroyo 4.1 though.

What OS are you using?
When you say the computer finds the phone, is that just a notification? Or is it listed with your drives or your devices? Does the phone recognize that it was USB connected in your notification shade?

I am running CELB 4.1. I just connected using a cable I have used before for this. Two notifications were added - one telling me that USB debugging is connected, and another telling me that "USB is connected - Select to copy files to/from your computer". Tapping that notification brings up the USB connected screen, with a button to turn on USB storage. Tapping the button mounts the SD card to my computer.
This is pretty much the way that CELB has always worked for me.

Thanks Doogald
Must have missed seeing that when I plugged it in.
Thanks a lot working like a champ now !
Sorry I posted this thread in the wrong place won't happen again

My Galaxy S4 won't stay connected to the computer via USB

Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?

No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

same problem with me!
every thing ok with s3 but the problem only with s4
please we need help to solve this problem!

Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.

I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

im on xp(retro yeah ha ha) but just a pc i have for my phones and stuff. But i got it working again by flashing my firmware through odin and its back working. Im blaming when i rooted it that it broke but ill see if it happens again
edit: Can confirm pc is now picking up phone. I just flashed the most recent stock rom for my carrier through odin and as soon as it finished updating its prefect now. Might wait another while to root it now and wait for more devs to jump aboard for more roms

I did check 'stay active while charging' in dev parameters and i never got disconnected again.

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.

My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.

It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.

I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!

Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.

Use a different usb cable and usb port. I know it sounds stupid but there has definitely been phantom problems which were solved this way, even with something as simple as adb commands

i have same problem. trying all the way but always with the same result...
