Greets gang,
Several days ago I started getting the subject message appearing in my WinXP system tray. It was on my Gateway laptop and it would appear over and over again, citing 'Unknown Device' when you'd click the annoying ballon. My Jam wasn't even connected at the time.
I basically blew everything away and restored my laptop to factory original settings. Problem persisted. I thought it might be hardware, but the message has now disappeared, only re-appearing when I plug in my Jam. My USB Bluetooth dongle plugs in fine, no errors.
Someone else had bent pins on their USB port or plug--I see none. Anyone else have issues with this, or can anyone offer some help?
Presumably you have installed (re-installed) Active Sync on the PC? As you may already know, as standard the JAM and many other PPCs are not recognised by the computer unless Active Sync is installed [properly].
www.softick.com provide an excellent utility to have your PPC recognise as a removable drive without using Active Sync.
Yes, ActiveSync has been installed & re-installed. New development? I plugged in an 80Gb external hard-drive to that laptop and Winblows is telling me its connected to a non-hi-speed USB port, which it is not. Could be something there.
I'm going to re-flash the Jam to factory ROM, then I will dig into the USB issue.
I had this problem and I tracked it down to the fact that I had picked up the wrong cable!
Same connector but for my camera
The wrong cable thing may very well have been it, but I was also having probs with an external hard drive I was using. I ended up rebuilding my laptop twice and now things seem to be fine. What a drag.

I have the same problem.
It seems, this problem appears mostly on laptops, not on PCs?
I tried to uninstall\install, repair with all ActiveSync data removal or leaving it - No result.
Also, tried to replace the cable (which is ok, im sure with the one from the camera) - No result.
Temporary way out: do Off\On with qtek9000 on cable connect.
Another way out: Turn On the "Enable all incoming beams" flag in Start -> Settings -> Connections -> Beam (this path may vary depend on your Universal brand name). As I seldom need to connect via IR to other devices, I have switched this option off to consume power.
DOES ANY BODY KNOW, HOW TO FIX THIS BUG?? Any Ideas?
Qtek9000 with laptop Toshiba Satellite Pro \ Win XP SP2
it seems dat a noob like me at last can give a help
i have the same problem last time, and as i trace it down, the problem lies on the cable.
as u know that we all use mini usb (usb cable type b) for our o2 mini, but not all type b cable support pc connection, some will only give charging access
i have 2 mini usb cables, one comes from my external hdd, and the other is i buy it myself. the difference is that the 1 i bought actually have a shorter connector (maybe the problem due to this)
so try to buy another cable, as i don't know any other way (reinsatalling pc os, hard-reset device or reinstalling active sync won't solve the problem)
NB. both cables are working when i plug it to my external hdd, so maybe the cable is not faulty. one of the advantage that i got is that i can charge my mini without disabling the active sync usb connection
sorry for my bad english
i can almost essentially confirm that it is NOT the usb cable.. I have been using a usb cable i had around the house for syncing my phone, and it has worked perfectly ever since I first received the phone (over half a year ago), but all of a sudden, i plugged in my device, and received the "usb device not recognized" error message... does anyone know the cause of this?
So I can't get my desktop OR laptop running XP Pro 32 to even recognize the phone. As in no audio plays and nothing appears in the system tray. Tried with/without debugging mode, installed the samsung drivers etc. The phone doesn't even show up in device manager at all- not even as something unrecognizable. Its as if the port is dead. The phone does 'ding' though and charge ok so it is receiving power... though nothing at all appears in the android notification tab when connected. Any ideas or anyone know of any apps on the pc or android side to take a closer look at whats happening on the bus?
The only way that I can get it to work is to put it in media mode. It shows up as a media device in Win7. If I put it on, "ask every time" or whatever it doesn't work and in mass storage mode it shows up as two unreadable drives, they are grayed out in Explorer... Basically...don't use the "ask every time" for USB function.
This function seems like such a simple thing, not sure why Samsung has so many issues with it considering they have been making media devices for a long time.
Anyway... do you have access to a newer OS to at least rule that out as a cause. Not saying it shouldn't work with XP 32 but just something to check out.
I was having similar issues at first. I take it adb doesn't work either? Well my fix was to delete my whole Android SDK folder, then I redownloaded it (though I just kept the "tools" folder this time). Then I downloaded "USBDeview" (google it) to delete every USB driver that had to do with android (basically just left the printers, HID, and my Sansa drivers), restarted, then I downloaded the samsung drivers from the thread on here, plugged my phone in and manually pointed the driver search to the drivers.
ADB and Mass Storage has been working fine since. All I can tell you is to keep checking cause there's something you're missing, I also thought to myself "what the heck else can I do?" since I had done each one of those steps previously, but maybe I just had to do them all together. Good luck.
another possible solution is to change cables if you're not using the samsung provided cable - some cables are charger only (no data) - some of the motorola cables are charger only and we've already had one poster that had that issue
I couldn't get it to work at first either. I more or less did this.
I plugged in my phone. I did not enable mass storage mode on my phone. Walked away and let my PC think for a while. I came back and I noticed I had two new drives. I then enabled mass storage mode and could connect.
Two of my machines I had to do this. I'm not sure why it wasn't instant, but it just took a bit of patience and walking away from the machine to let it think for a while before I guess it installed the drivers and made its peace with the fact it wasn't the G1 any more.
Say into voice dialer "Open SD card" -> check "Enable USB mass storage". That works if port on PC is OK.
If it's a driver issue, open device manager and uninstall the usb ports. Unplug everything from usb and when you reboot the computer it will automatically reinstall the usb ports.

I ran into the same issue. It was a problem with the USB cable I was using. As soon as I tried a different cable it worked fine.

I second this, I forgot my sammy cable at work on Friday and on way home stopped at T-Mo and picked up a charger w/cable and realized right away this was just a charging cable as soon as I connected it to my PC. I'm returning the cable back to T-Mo tonight. At least I was able to charge my phone over the weekend.
UPDATE: You guys are right, it is the goddamn cables! I bought an extra wall charger + cable at the t-mobile store and was using that at home. I had left the original in-box cable at work. Tried the cable at work today and now the drives pop up. Still don't appear writeable but I can look into that when I have time, probably the typical driver issue. As far as I can tell those separate cables are power only! $15 for a two wires + dc adapter. Thanks Samsung. Grr.
i suspect the mfgrs have gone to charge only cables to help keep folks from tethering - just a suspicion
if the "drives" are popping up, have you "mounted" the phone (pull down notification bar, clik on USB connected and it should give you a window asking to mount the cards or drive)
FYI....The Rocketfish cables you get from Best Buy do not work. They are only capable of charging.
@larryccf...I don't think certain manufacturers are implementing this on purpose so we can't tether. I think their just being cheap.
Where I got my cables on the cheap! and my problem.
I got my cable at monoprice.com. Check it out that is a 10 foot usb cable for $1.69 and it works for me. They have different lengths and even some colors. Now my Mass Storage issue . . .
My Mass Storage via USB works fine unless I enable "USB Debugging" which one of my apps needs to work. Once debugging is enabled I loss the ability to see my sd card and internal storage on my XP netbook. any ideas????
Same Problem
I have the exact issue, tried many things have'nt found a fix yet. Any help would be greatly appreciated!!!
Thanks,

this worked for me Thanks
Yes phone is mounted, and can be seen w/o usb debugging enabled. However with usb/debugging on it does not read the phone being connected. Meaning that I cannot connect to ADB which is my main concern.
thanks for response tho,

This is my issue exactly, and I haven't found a fix either. Called T-Mobile and they thought turning off debugging was the only fix I needed.
Most of them, sorry to say are half retarded. They think a data reset is the cure-all

Ain't that the truth!
If you are running windows (x86 or x64), it would be wise to install the samsung drivers. I was having this exact problem, but as soon as I installed the drivers from samsung, viola!
I had the latest drivers from google, and they did not work for me.
Here is a link to the thread containing the links to the drivers, thanks to TGA_Gunnman:

Hi!
Ive got a big problem cause my Galaxy S just stopped being recognized by any PC. I dont know whats wrong, it just treats USB cable like it was a charger, PC doesnt detect anything neither does the phone. Its very strange since everything worked perfect for the last couple of weeks. I tried to connect it to a notebook i used to flash the phone a week ago and it has been turned off ever since so it cant be any driver related issue. Im afraid my micro-USB port is damaged but i have a custom firmware in it and since i cant reflash it the warranty isnt vaild ehh...
Any ideas?
THX
silly question...
Do you mount the phone via the status bar after you plug it in?
Thats the point - PC doesnt detect the phone AT ALL theres not even a sound that an USB device has been plugged in. The same thing in the phone it just starts charing it doesnt seem to know that its connnected to PC.
sounds like your PC mobo got the USB port fried.
try turning off the PC, unplug the power cord, wait for the energy to drain out, then turning it back on
my Windows 7 x64 some time does that, but it's not a hardware error
on yours it could either be a hardware dead, or the Windows gone Bezerk as usual
I tried different USB devices - other phones, pendrives and a printer and everything works fine except for the Galaxy S. The Samsungs USB cable also works fine with other phones..
I wrote to Samsung and they said to send them the device because its most probably damaged :\ Will they check the firmware version?
btw. as I said in the first post the phone doesnt work on my notebook as well
I wouldnt care so much about this because I can send files using ftp but I cant change the firmware without an USB port working (or am I wrong?)
I sometimes also have this problem. For me rebooting the phone and if it then doesn't work again using another USB port at my PC solves the problem.
Yesterday when the problem occurred for the first time I removed SIM and microSD cards and PC detected a device but it was recognized as 'unknown malfunctioning USB device' but no luck ever since.
Just to let you know my Samsung just fixed itself 0_o Might have something to do with the Windows reinstallation on my PC but it suddely works on my notebook as well. Im really confused now...
Hi guys!
I've had a problem over the day with my beloved HD2, and I've started to fear that it might actually be the hardware starting to decay. About a day or two ago, when inserting my phone to the MicroUSB cable, it recognized the HD2 just fine, had access too USB mount, ADB and all of that. Transfered some music to the SD-card (Trancent 16gigs Class 4, btw - still very well recognized by the phone to the time at writing this), but now, some time later I get nothing out of connecting the phone to either my laptop or rig.
I know it's not the drivers or the cable, since I've tried with others cables and a few other computers. The message is the same old "The device could not be recognized". But the funny thing is, somehow the device must know that its connected to a computer anyway, 'cause it instantly enables debugging and the option to enable mount. I, as of now, has had no luck getting into the SD card, sadly. Not even been able to pull logcats or anything, setting up wireless ADB hasn't been sucessful either - so where I stand now, I'm kinda in need for a helping hand.
Has anyone else ever had this problem too, or am I left out in the cold?
By the way, even managed to put on an older nightly CM9 build, as it was stored on my SD. No luck there either. MAGLDR mount / recovery mount doesn't function either. Same error.
The ROM I first had the problem on was PARANOIDANDROID v0.6. Then a nightly CM9 from sometime last week. Both immensely close to stock and ICS based. LEO512, by the way.
Please, give me a hand!
TL;DR: USB broken, still charging, help.
Your usb is getting loose (usb data connection becomes irratic and then stops working, continued use results in USB port ripped from mainboard), try to not use it while plugged in and see if the repair shop can fix it for you without breaking usb data. You can use the SwiFTP app in playstore to transfer files in the mean time.
You may also want to use a cradle charger to minimize USB port being used.
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.

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.

I am already put fresh win 7 but still same problem..
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

Hi
I don't know if it may help but i noticed the usb doesn't work when the phone is locked.
I did check 'stay active while charging' in dev parameters and i never got disconnected again.

Tested it out on a fresh copy of Windows 7 and it still continuously disconnect. What gives?

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.
Any way to connect in master storage with out root.

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...
