Hi guys, I just got my Atom Exec this week, and I have the following problem. When I activesync my PDA with my laptop (via USB) my internet conection(on laptop) drops. It is a wireless connection, and I've tried to fix it and nothing, any ideas?
What's the spec of the laptop? (OS/Network/SP2)
Windows XP SP2 Laptop and wireless network through a router
Could be a number of things, interupt request, com port problem, try reinstall USB drivers and modem drivers and make sure you're running latest Activesync. Also if you're connecting USB via a hub to device that can be problematic, connect direct to USB port instead.
I'd hone in on the firewall - see if there are any errors in the logs.
I just got my Galaxy S2 yesterday, and I'm trying to get the appropriate drivers installed on my PC so that I can go about rooting it.
If I just connect my phone to the USB port, I see a new Portable Device, "GT-I9100", and I can browse that to see my phone's filesystem.
But Kies fails to connect to the phone (It just sits there saying "Connecting..."), and if I look in Device Manager I see, under "Other Devices", a device called "CDC Serial", which doesn't have a driver installed.
I've tried un-installing and re-installing Kies which, according to my web searches should install the driver, but it makes no difference.
I understand this driver is a prerequisite for being able to run Odin and root my phone.
I've searched this forum and Googled my question and have yet to find an answer to my problem.
I'm running Win7 64-bit.
Anyone got any ideas?
Did you install Kies on your pc? I had a similar problem yesterday but solved it after downloading Samsung Kies from www.samsung.com and it worked perfectly.
You need to download Kies manually onto your pc in order for Kies on your phone to detect and connect to your PC.
Yes I installed Kies, which is why I mentioned "I've tried un-installing and re-installing Kies"
That was the solution I'd found by Googling, but it had no effect on the problem.
Are you using 64-bit win7? I'm wondering if that's relevant to my problem.
am using Win Vista...
hmm.. sorry mate.. can't really advise u... cause I am just a noob like you.. Lol.. good luck with that~!

I've been facing the exact same problem on my system (Win 7) as well (Thankfully I updated my phone firmware while I was on older version of Kies so Phone is up to date <I'm using the Indian version of the Galaxy S II. PHONE: I9100DDKE4>, however the CDC Serial driver issue started as soon as I updated Kies).
I tried downloading a driver set from the internet for Samsung Galaxy S, - but that didn't work either.
I had earlier updated Kies using the Kies updater itself and thought that might be causing the issue, so, I downloaded the .exe of the new Kies from the Samsung support website and installed it again - unfortunately, this didn't work either and the CDC error remains.
I also tried using different USB ports to connect my phone - again - no luck.
I will try some more troubleshooting once I get home from work and will let you know if anything works out.
In case you are able to figure a way out - please do share the resolution steps.
Tried and failed. Haven't even got Kies on my PC any more. If you are going to root and use custom ROMS then just use Odin. Can't really see any use for Kies.
@davedontmind,
Something simple , but, go into settings/applications/development and make sure usb debugging is UNTICKED. Kies wont connect to the phone if you have it ticked. Also, dont run odin and kies at the same time.

Hmm, I am having Win7 64-bit. I also had the same problem with CDC Serial and Samsung_Android being in the unidentified devices in the device manager. Then I downloaded and installed Kies. After that connected S2 with USB Debugging checked (enabled), the drivers began installing on their own from Windows update. Now I have a 'Samsung Android Phone' as a device and 'Samsung Android ADB Interface' under it.
Hope this helps.
choose reinstall drivers throught kies solved fo me !
I had the same issue, and even choosing to reinstall drivers from within kies didn't work, but if u browse to program files and look for the kies folder there should be a folder called usb drivers with an exe in, run this and all should work fine.

Possible solution CDC Driver and Keis Connecting Spin
I've been fighting with this off and on all today.
I have had no joy with the downloads of the drivers at all (the all seemed to error out on install). I am using Windows 7 (32 and 64 bit).
I found a mention somewhere else about "USB Composite Device" being detected as part of the install chain. Sorry, I can't remember where, but it sent me down a path of thought. They were right, it does get detected.
The KEY thing is that THIS is wrong and it then causes all the other problems I believe.
It should be a "SAMSUNG Mobile USB Composite Device"!
If you change this to correct device (and you might need to make it something else to force it to go to the net and get it) it will then find the others correctly too (although you might have to unplug and plug in a few times).
BTW, CDC becomes a "SAMSUNG Mobile USB Modem" and the MTP becomes "GT-I9100".
And then everything is right with the world (and Keis seems to find my phone!!).
And now finally I can go to bed happy .

Man..i`ve been trying to solve this retard problem for like the last 10 hours..and ur small tip saved my ass just now.. Thanks alot
You dont need to install Keis to get the drivers (win7). As Gavin stated the device will be listed as a USB composite device (under Universal Serial Bus Controllers) , just right click and update drivers on the composite device and it will then change to SAMSUNG Mobile USB Composite Device. Your phone will then be listed as a SAMSUNG Andoid Phone higher up with a subtree giving an adb interface.
Phone in USB debug Mode
Plug in USB
Windows 7 searched for drivers (none found)
Control panel -> device manager
Universal Serial Bus Controllers -> USB Composite device
Right Click -> Update Driver Software (net connection needed)
Do the above step for each USB Composite device if you do not know which one to update.

Still nothing.
No driver found
cdc serial error.hardware drivers not found error
please install Kies updated version manually as it contains hardware drivers for all samsung models.it worked for me.

i can confirm that this worked for me - cheers gavin !
i just worked my way through the USB Composite Devices that were listed under device manager, choosing to Update Driver Software then Search Automatically For Updated Driver Software and one of them turned out to be my phone.

I can confirm that this works for XP64 with the only change being that "device manager" is under "System". Thanks for giving the obvious (in hindsight) answer. MS had the drivers we needed!!!
I was actually looking this up for a band-aid fix for the 10.1!!!! Worked like a charm.

i'm trying to tether a sgh-i777 (at&t SG2) running CM7.1
wifi hotspot just says "Error" after disconnecting existing wifi.
so i'm trying USB but i can't get windows to install any USB modem drivers.
i tried the ones from samsung, by themselves.
i tried the ones that come with kies (i'd assume the same version as above) and i tried the google android SDK usb modem drivers
windows just refuses as it can't find the "appropriate software".
windows XP
any ideas?

Don't you have to flash back to stock in order to install Samsung drivers or Kies? I could be wrong, but I'm sure If you search you'll find your answer.
Ok so im trying to connect the phone USB but it gives me only options like im connecting a camera photo and scan in windows lol? how do u access the phone so that you can transfer files i dont understand, never had a problem connecting a phone this way before.
I had this problem too.
I'm using XP and I had to install a driver for windows called MTP I think it was.
Once I restarted it worked. Make sure it is in MTP mode when plugged in via USB.
Probably worth trying
EDIT: Just realised I think what actually fixed it was installing the Samsung USB Driver for Mobile Phones (I installed 1.4.8.0 which I think was the latest)
Google it and download should do the trick
Thanks that did the trick installing USB drivers, i found them from here if anyone else has the same problem.
