Not recognizing Epic 4g as a USB drive

[Intentionally Blank]

Recently switched from XP to Win7 64bit (new PC). XP worked fine, but I found only rare success getting Win 7 to recognize the phone. I was using the Samsung provided USB cable. I tried all 8 of my USB jacks without luck. I downloaded & installed the Samsung driver without luck. Note here that Win 7 always told me that the Samsung driver was not correct for my device.

After I plugged the phone into USB port and was told by Windows the device would not work I entered troubleshooting mode, deleted the device and drivers and search for new devices. Mostly this did not work, but a small percentage of the time it would recognize the device and I could browse the phone. But if I unplugged the phone and plugged it back in the phone was no longer recognized.

My solution was this - I had a 4 port powered USB hub that I used with my XP box because it had no front USB ports. I plugged it into the Win7 box and plugged in the phone. Bang! Phone is recognized every time without fail. I don't know if it was because of the power drain on the USB port, or just that the hub acts as an intermediary but whatever it is it just works. My guess is that the issue lays more with your motherboard's USB ports than with either the phone or Windows 7.

If you have the USB Debugging checkmarked then your computer will not recognize the phone. Uncheck it and connect again. Hope it helps

the more power supplied the better, thats why people have trouble sometimes depending on what USB version they are using. When a phone bricks the reason people cant get it back up is because it takes a certain voltage to push it back on .

Ah but you see my computer does recognize the phone. If I plug into my XP box I have no problems. If I plug into my Win7 box I have no problems as long as I'm connecting via a USB hub rather than directly to the computers USB port.

This is aside from the fact that according to the instructions I've found for checking the USB Debugging setting I have to install the developer SDK, and a Java JDK on the phone to be able to have the menu item you reference to see if its turned on or off.

Although I appreciate your information, for the moment I'm happy with the USB hub as an interface.

Intentionally Blank, you just totally saved me! I spent forever working with my 32 bit Win 7 to get it to connect, tried everything! I knew it'd worked before too, but couldn't remember how. Tried every port, and finally plugged into a hub like you said.. it works perfectly!

Thanks for the heads up!

ugh

15" macbook pro running 10.6.6

debugged, mounted, etc. - nothing. using original cable.

occasionally i get the "disk not readable" message. occasionally i get the network menu. ONCE iphoto popped up with NO NAME under devices. i scrambled to go to finder - all i want to do is pull off some videos that are too large to send to myself - and was about to drag and drop when the drive vanished. also, i have to restart both the comp and the phone or nothing happens when i tell the phone to mount.

if it's just that the two usb cables are too weak, i am going to be seriously angered.

Try it with USB Debugging off ([menu] -> settings -> applications -> development -> USB Debugging) . With debugging turned off, does your phone display the button menu Charging, Mass Storage, Tethered Mode?

If this doesn't seem to work with either cable on any of your USB ports, you may want to try another computer. Also, if you have a powered USB hub, go through that just to rule out power issues.

Thank you, thank you, THANK YOU! I am excited. I just lurk. Don't post cause I'm really not smart enough to contribute anything of substance, but I do learn a lot. Not being able to sync my Macbook Pro to my Epic has been killing me. The pull it apart to have to plug the SD card into the computer, to putting it back in the phone and waiting for the "scanning card" has been horrific. And don't forget the step where you go to settings and "unmount the SD card" before you remove it. I have tried all combinations over and over, and the Epic WILL NOT mount to my Mac,....... until now. On my own I would have NEVER thought to plug it in through a USB hub! Works first time, every time. You guys are the best!

Running Win 7 64 bit and sometimes my computer does not recognize the phone and if it does, it runs so slow moving files over or opening folders

It doesn't matter if my phone is in debug or not my windows 7 64bit Dell XPS9100 will not reconize my phone. My wifes Windows 7 64bit Dell XPS laptop will reconize it everytime. I thought my motherboard was bad and Dell swaped it out for a new one. It still does not reconize the EPIC.

After reading that a powered USB hub will work I plugged my EPIC into the powered USB hub built into my monitor and it worked. I am very excited about this.

i have an interesting problem. my epic mounted fine through my computer until a few weeks ago (macbook running osx 10.4). the phone will pull up the charging, mass storage, tethered mode menu just fine. i click mass storage and i mount it, and then it does not show up on my computer. any ideas?
