USB issue

All of a sudden my pc is not recognizing phone as a usb drive.. It was working perfectly since day one with this phone but since yesterday it wont recognize it.. And even if it does, it takes a very long time. ive treid uninstalling the drivers and reinstalling, as well as turning debugging on and off. My pc is running windows 7 64bit.. I have also tried different roms and nothing.. When connected in debugging mode, it recognizes it immediately and installs drivers by i still cannot view my storage card.. Any help would be appreciatied.. Thanks

Install pdanet on your computer. When it gets to the part about driver installation, select samsung and voila.

Seconded. I bought a cheap charging kit and the cable would charge but would not allow file transfer. Took it back, bought another cable and it's fine.
Either the phone is finicky about cables, or it might just require a particular type (probably USB 2.0).

I had this issue also last week. I tried another cable and it worked fine.
But now I am having issues with my usb ports in general. Now they just stop working every once in a while and I am required to restart my laptop.
Don't know if the two problems are related.

Try different USB ports. Like the ones on the back on your computer.

I've been having the same issue. I went out to Radio Shack and bought a new data cable. So far all ports on my laptop, winXP pro 32bit, and my win7 64bit desktop have not had problems.
I'm thinking that the USB cable supplied by Samsung is crap. I tested them both out on the same machine, same port; the new one worked fine, while the stock cable only gave me adb access.

I had this same exact problem. I kept thinking the phone was going bad or something. I tried the cable that came with my Epic & the one that came with my Moment, both didn't work... for some reason it worked find on a Mac though. So when I gave my mom my Moment when I got the Epic she bought an extra micro-USB cable and I decided to try that one, for some odd reason, that one worked.
Still don't know exactly what was going on but a third-party cable fixed the problem for me.
Hope this helps.

"usb device not recognized" with two diff. win7 installations.

as title states.
It doesn't seem to be the samsung drivers
as I have uninstalled and reinstalled.
but the Android drivers. I have no Android drivers installed anymore
(the 3 of 4 that installs)
therefore i lose adb connectivity
*This has happened on 2 different Windows 7 installations. (switching between 2 different hdds, on this laptop)
I have usb debug on ofcourse.
I have uninstalled reinstalled latest samsung drivers.
I have installed pdanet drivers.
I have turned off phone, while connected then boot up. still no fix.
I am using acs froyo dk17. But this happened with dk05 as well.
Is there a fix for this?

I've had this problem twice. The way I fixed it was to wipe the sd card. Its a pain but that's what fixed it

If not a driver problem (doesn't sound like it is) the next *usual* suspect would be the usb cable. The samsung cable that shipped with these phones is crap. I got a 6' belkin one on amazon for $8 that has worked flawlessly.

Make sure you're not using a USB port that's on a hub or daughtercard. It should be one that's directly on the motherboard.

I kept fiddling with settings and rebooting both phone and computer and got past this once on my old win7 box. On my new one, I got nowhere after an hour or so. Worked first thing with the same cable on my win xp machine.
Plug your phone into a USB1 only hub, or on the same channel as a usb 1 keyboard or mouse and it will detect just fine... it won't really be useful because it won't be able to flash still (I believe it should detect as a composite device with several facets and only some of those are usb1-only compatible). I believe that the underlying problem is a bad implementation of the usb spec on one of the usb2 only parts, but I didn't feel like digging any deeper. I might try a win xp vm on the same physical hw to see if I can narrow it down to a win7 usb2 + device usb2 compatibility issue. Might be worth making sure our win7 patches are up to date, too.

Thanks for the replies guys.
The usb trick won't work because it's a laptop. And I tried all four of them. I only have windows 7 machines. One being a ultra sff and has like 12 usb ports. It hasn't failed me yet, but happens on the laptop.
It wouldn't hurt to get another cable, a longer one. And my sd is maxed out, I will pull it instead of format.
Thanks all

I had this problem. Plugged into the back instead if the hub and reinstalled everything. Now it's working like a charm on all usb ports. Really odd problem.

I had this problem. I was using a USB extension cable that was a bit long. All the other phones and USB devices worked fine with it. EPIC did not want to. I got the impression that EPIC needs more power from the USB port than most of these other devices. For me, skipping the USB extension cable did the trick. I also used a powered USB hub and that worked well too. You might want to try different USB ports. Some may provide more power than others. Also try a powered USB hub (some are built into monitors) if you have access to one.

I had the same issue with my laptop as well. It is most likely the cable. The samsung one is crap. I tried every port and installed the usb drivers a dozen times with no success. Used the cable from my wifes blackberry and worked on the first try. Just pick up a new cable. Try monoprice.com they have awesome deals.

I just had this problem, I switched my cable and then it worked fine.

Also make sure your antivirus is off although that's likely not the culprit. Do you install the drivers as administrator?
Try a new cord. If that doesn't work, try deleting/uninstalling the device and/or hub from the device manager - plug the phone in, letting win7 do its worst by not recognizing it, then open the device manager and find the usb hub. try deleting/uninstalling. unplug the phone and scan for hardware changes. I think this may force windows to reinstall the drivers for the usb hub. Disclaimer, it's been a while since I spent significant time fooling with windows computers so take this advice at your own risk - I'm feeling my way like an old man with cataracts trying to find his way around his long-lost childhood home. in the dark. With unfamiliar furniture. In an earthquake. While in a wheelchair. With flat tires....
My computer did this for a while and now it doesn't although it's certainly possible I changed the cord I was using.

The best way to get drivers to work is install PDAnet IMO..
I had driver problems upon driver problems.. swapped cables, etc.
went through all the motions that you all are describing here and what fixed it for me was installing PDAnet. Worked like a charm.
Hope this helps.

I agree about using pdanet for drivers. Unfortunately this problem isn't with the driver not being installed correctly. I got it on one machine and not another, using the same friver. In fact I got it to work on the same machinewith the same driver ... just different ports (one was stuck in usb1/ohci nd worked, the usb2 port never worked on one machine and a usb1 port never worked on a different one).

This worked for me when I had the problem. This will be the second time I had a usb cable go bad on me. Maybe I shouldn't buy those cheap ones from China...

I've had this problem with numerous cables on Dell E series laptops with 3 Epics and a Moment. For the life of me I couldn't get the phone to be recognized when using the USB ports on the left side of the machine. Plugged it into the ones on the right and have never had a problem. I think with the Dells it's a low current issue on the left side ports. The shorter the USB cable the better off you'll be if it is a low current problem.

thanks but i did alot of that last night and today, uninstall/reinstall drivers, usb hubs.. nothing
i may need to try another cable because i am workign on a friends epic sunday.

It HAS to be the power differences NOT cable.
Same cable as I charge with, plugged into the front of the computer (hub).
Plugged into the back of the computer recignized the first time.
=USB power

In my case, tried several micro USB cables, no dice. Tried my laptop and desktop, no dice. Tried USB hub or direct to PC usb ports, no dice. Device manager shows the right comm port but all the one-click roots i've tried can't find the phone. USB storage has never mounted for me from day one either.
Sigh, never had this issue with any other Android phone.

Finally figured out my issue. I had set it to "modem" while doing something else in an epst menu rather than "pda". Since I corrected that, works dandy.
I feel so stupid.

Would using my friends droid x cable work with the Samsung epic?

[Q] USB Mode

Did anyone ever find a fix to the usb problem some epics have? Every time I plug my phone into any type of computer, it will work for the first time I plug in, but if I unplug it and plug it back in, my computer says usb device not recognized. This also happens in my BMW, it let me listen to music through the usb once, and that was it, now it doesn't even read it. I've heard of others with this problem, but I haven't seen anyone fix it. I don't have Sprint's insurance, so I don't know how things go towards getting a replacement. I also tried downloading an app to automatically mount when usb is connected, but no dice. I have tried different microsd cards too but same problem.

i only have this issue on damn dell computers it seems, i dont think there is a fix, however what i do to get it to recognize is just unplus both the connector to the phone and the usb from the computer, and then it registers finally.. Its very annoying but it will work, just try that, i hate that but only have issues on dell, my 2 HP's work great with connectng

Changing the micro usb cable also helps. The one that came with the phone is garbage. I personally use the cable from my evo

[Q] My phone won't connect on USB to computer, but my wifes Epic will

I have a Samsung Epic 4g rooted with the one click 2.5 and I upgraded to Froyo.
I had to use my wifes phone to copy the update.zip to my sd card because my computer would not let me see my epic. Same computer, cable and model phone works fine for my wifes.
I need to reinstall the one click root and can not get my computer to see my phone.
Is there a way I can root on the phone without using the computer.
So close to done, but I can not use the wifi tether without re-root

Different phones can be more finicky. No valid explanation why though.
Make sure you plug the cable into the phone first, then the computer. Try using different USB ports. If all else fails, try another cable.
I have seen a bad port on the phone before, but it had charging issues as well.

I have tried all the ports on my laptop. The phone acts like it is connecting. Even brings up the new usb connection icon but can not see the phone or sd card on my phone. USb debugging tried on and off.
No problem charging. I have tried various usb cables also and different computers

That is pretty wierd.
Do you have a different computer to check?

I'm having the same issue, but it isn't constant. I spent hours last night reinstalling drivers, different cables, debugging on-off. I go back to stock and try and it works fine, I install clockwork3 and ext4 with TrulyEpic and it does the same thing. Though sometimes it works. I found that my port is a little loose, cause when I move it to one side it looses connection. I think we may need to contact Sprint and get a replacement phone. I really want a brand new one, cause I didn't pay for a refurb, and really dont want one.

Sounds like something is up with the phone, man. The only commonality is the phone.
Especially if you couldn't access it before the flash to 2.2 either.

duh. It's already been scientifically* proven that phones perform better for women because they are often carried (snuggled) in the women's bra. See here...

I find my USB very finnicky on my phone connecting to my windows 7 computer,I've gotten used to just using File Expert to wirelessly manage my SD card.

[Q] Help with my usb?

Hi, I'm new around here although I check in periodically to see if you guys have anything cool that I can put on my Continuum My phone's usb broke recently, but luckily I still have one from my old phone from like 2/3 years ago, the LG Chocolate Touch. Anyways, I want to install a ROM on my phone, but I can't seem to connect the data. It has let me connect the data before, just at random times. Like, it charges fine but I can't access the contents of my sdcard. Is there any way to fix this? (Sorry if this is the wrong forum, as I said, I'm new here, and I'm in a bit of a rush.)

I'm almost positive I did.

I've used USB cables from both LG and Palm to transfer data and even install roms on my Continuum. Most cables are built exactly the same, except for some Motorola and Blackberry cables I think. So I would think it has to be your drivers, try unistalling and reinstalling if they are already on your computer.
Edit: Also, my computer seems to recognize my phone faster if USB Debugging is turned on.
