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.
anyone get the error message of unknown device when plugging in their wm 6 phone to a laptop, happens to me on vista homepremium and xp, both up to date. this happens about %50 of the time
I bet your USB port on the laptop is not supplying enough current (borderline, hence why it works sometimes). Try one of the following things, first try the connection while the laptop is on AC power (not internal battery). Second, do you have a double USB port adapter? This is a cable that plugs into your external USB device on one end, and has a Y-connector that plugs into 2 USB ports on your laptop, thus increasing the current capability. If either one of these suggestions solves the problem then it means the laptop is not able to supply enough current on one USB port, a common problem.
I had the same problem and found it to be a firewall issue
Ofcourse it could be a firewall issue or any issues with loading of drivers and services. A soft-reset on the device and a PC Restart will solve most of the case!
Regards,
Carty..
How would a PC Restart make your firewall accessible, I located the SmcGui.exe (symantec) created a shortcute, and use that to disable to firewall whenever I want to connect

hi guys thanks for the advice, however, i have since updated to vista ultimate and now get the following issues. xp seems to have sorted itsself out, however vista has problems installing the drivers for my phone. it says on the phone check usb cable and on the laptiop i get the symbol in the sys tray for unrecognised device. the phone will sync fine, just not allow internet sharing.(i am using a 2.0 usb port and my mobile device centre is up to date, i downloaded all the vista updates today)
my firewall has been turned off, but i believe its a driver issue as thats whats showing on the screen device not recognised.
any ideas?
For Internet Sharing in Vista, you need to install WMDC.
http://www.microsoft.com/windowsmobile/devicecenter.mspx
i have it installed, i tried changing from official rom to black satin and a few others and it still does the same. the mobile device centre will sync then i turn on the internet sharing and it installs the drivers for "unknown device". had a word with the t-mobile connectivity team who took a look at the laptop and phone, tried it on other laptops with the same result. vista doesn't like the internet sharing bit. tried the usual stuff like taking off the advanced network functionality etc.
oke here is what u gotta do :
for windows vista:
-reboot computer without wm6 device connected
-install mobile device center 6.1 (the drivers ^^)
-reboot
-wipe all activesync connections on wm6 device and vista
-disconnect device and see if advanced networking is enabled (USB to PC .. in networksettings wm6)
-set connectionssettings in mobile device center from automatic to Internet
-goto networksettings on wm6 device and choose connections
-tap advanced and select networks : both set to My ISP
-connect wm6 device and wait till it finished .. take some minute or so
installing drivers and things
-when its done unplug device and reboot computer (yes again, and i am not
going to explain why this is so important as you should know by now)
-wait for the computer to boot untill it finished (vista this take 2 minute at least)
-connect wm6 device and setup proper sync partnership
-goto connectionsettings in mobile device center and check all boxes and set it to internet if it is not allready set.
-wait for the device to do its stuff
-it will strangely reconnect after a while and internet works again
notes:
kaspersky 7 : -turn of the kaspersky protocol on the networkadapter of wm6
-allow acces to svhost when it asks for it.
norton 360: -no problem found .. maybe you need add LSP to trusted
networks
internet+wmdc 6.1
double post ...
moderator remove this please
hey dajojo yer guide is great , i tried it and unfortunately, it connected for about 30 seconds and went straight back to usb device not recognised.
when it was connecting it should show up as "generic rndis internet sharing windows mobile device" or something similar.
any further assistance would be great.
m running vista home premium 32 bit (went back to it from ultimate)
Finally Solved!
Hi there!
Seems to be the same problem on HTC Dual!
try this
go to start>settings>system>power>advanced
if the checkbox "When device is turned on, do not charge battery when connected to PC" is checked uncheck it and tap ok! Then go back again and check the checkbox again and tap ok again. and the ActiveSync software will sync all data!
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 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 just received a replacement S2 from AT&T, my old S2's USB port went out. I am wanting to root through Odin and get CM9 back on but I can not get my phone to connect to my PC. I have tried on my main PC Windows 7 64 bit and my laptop Windows XP. The phone is running 2.3.6 KK6. When I connect it I see MTP Initialization followed by MTP Connected on my phone, but nothing on my computer. When connecting in Mass storage mode by either enabling usb debugging or through settings -> wirelss -> USB Utilities the phone will just beep when connecting. I've tried the following to fix:
- Installed Kies, Reinstalled Kies
- Installed just the Samsung USB driver
- *#7284# on my phone and made sure PDA was selected under USB. Even switched to Modem then back to PDA.
- Tried removing my MicroSD card
- Multiple reboots
- Tried 2 different cables
- Tried different USB ports
Any other ideas on how to fix?
Try this dude.

First thing I would try is to completely uninstall the usb drivers in Windows, and then reinstall the usb drivers from this thread.
Well...I fixed my issue and want to headbutt a kitten as well. Turned out that I wasn't using a MicroUSB cable that was able to do Data as well as charge. Guess all MicroUSB cables are not created equally. I had 3 that I tried and they would just charge the device. I talked to Samsung and they asked if I was using my "Official" Samsung cable. I thought I was, turns out I wasn't. I went to Walmart and got a cable certified for Data and all is good in the world. Connected to my PC instantly.
So if you are having issues, check to make sure you are using your Samsung cable or one that is certified for data.
