Direct link to driver download:
Have you tried a different cable? I have three: One came with the Epic, one with an OEM charger that I bought to keep at work, and one came with my wife’s LG phone. All look the same. My computer runs Win 7 64-bit.
When I connect with the LG cable, the battery indicates “charging,” but there is no indication on the phone or the computer that there is a USB connection.
Using the OEM cable, the phone thinks it is connected, giving me the “Mass Storage” option, but there is no recognition on the computer that anything has been connected.
But when I use the Samsung cable, I get immediate recognition of an external disk and can explore all the folders from the computer and download my photos.
While trying to get this working (naturally, I used the right cable last!), I installed, then uninstalled the downloaded driver, which I don’t think is necessary.
I suffered from this problem. After beating my head against the wall and Googling, I noticed this thread.
In my case, I was using USB extension cables that were just too long. As long as I plugged straight into the computer, the problem went away.
Funny thing, none of my other devices ever experienced this problem before. My Samsung EPIC 4G is a bit touchy about this issue. I think its output power on the USB port is weaker, compared to other devices. Perhaps this is their way of saving power.
Anyway, the problem is solved for me now.
Remember, do not use USB extension cables. And always use Samsung provided USB cable. If the problem still does not go away, try one of the powered USB hubs. My monitor has one built in and that is what I am using now.
I am also seeing this problem. I have installed, uninstalled, and reinstalled the Samsung device drivers on Win XP SP3 32 bit and the device refuses to properly connect to my PC. When I try to mount the device I recieve a device I/O error.
I suspect the driver is also conflicting with other drivers on my PC as when I now plug in my Epic phone my usb Wifi device stops working.
I am runnining out of possible work-arounds for this problem. Any advice would be helpful.
Use the Samsung cable and plug it into one of the USB ports on the back of the PC connected directly to the mother board. If that does not work connect via a powered USB hub. Hope this helps.

Just to clarify - you only need the Samsung drivers to connect the Android debugger and for other "development" related activities. If all you need to do is mount the SD card so you can transfer files back and forth, all Windows systems should already include the proper USB mass storage driver. Be sure you have "USB debugging" disabled. Settings->Applications->Development->USB debugging (should be unchecked).
Summarizing what I've discovered since my post a month or so ago:
A hardware engineer friend suggested that there may a USB pin voltage issue on the Epic, which is why it has more trouble connecting to more ports on more systems. Either that, or there is a software driver incompatibility issue/bug between the driver running on the Epic and the driver running on Windows.
Sprint/Samsung, you clearly have a common issue here. I can reproduce the "USB device not recognized" or "this device can run faster" error on every Windows system I have access to. btw, my son's Epic has the exact same behavior across all these systems, so it is unlikely to be a hardware issue with my Epic.
I hope this issue gets attention from Samsung. Although I have some USB connectivity with the Epic, it is poor at best.
Exactly right. I went through the same process, uninstalling and reinstalling. Then, reading this last post, I just tried plugging in to my powered USB hub instead of directly to my computer (a macbook running bootcamp). It then came up fine. These macbooks have weaker USB power-- that must have been it. (ps, i was actually using the stock samsung cable, which is pretty long)
Here is what worked for me on XP 32 bit.
Install the driver -Motorola_Consumer_Driver_Installation_MotoConnect_01.01.12_32_bit_4.1.0.msi
plug in Epic using a rear USB port.
Press mount on Epic
Under Start /control panel /system /hardware /device manager /
look for the yellow question mark thingy that says Samsung SPH-D700
right click /update driver and then install from specific location
click the check install from list or specific location (advanced)
paste ---> C:\Program Files\Samsung\USB Drivers\03_Swallowtail
or whatever drive letter Motorola_Consumer_Driver_Installation_MotoConnect_01.01.12_32_bit_4.1.0.msi installed to.
It should then work. I would guess Vista and 7 are similiar.
Sprint/Samsung I will gladly accept a check for a couple grand for doing your work for you. ~shakes head~
I have a MacBook Pro and when I first got this phone I plugged it in no problem. The phone mounted on my mac with zero issues. Then sometime in October they released the update on the Epic after installing that.. I can't get my phone to mount at all. I have been in touch with sprint service via phone, and in store as well as Samsung phone service. They all want to give me the same crap "Debugging, restart, powered usb.....etc" None of it is working.
I actually took my phone and MBP to a sprint store and they wanted to argue it was my computer. They were able to mount my phone to their windows no problem. Then I told them it was after the update in Oct but he still wanted to argue, untill I took my MBP over the floor model plugged it in and it worked perfectly. I asked did you guys do the update and he said No. I said see here is your problem... the answer i got was. "well.. hmm guess your just $h!t out of luck".
Now is there anyone who has been able to get any better service than this? I've been trying to get this resovled since Halloween. I left sprint 5 years ago because of their awful service. We decided to give them another shot just for this phone. Starting to question that move.
