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!

When I try to sync (ActiveSync 4 installed) As I plug the XDAII into cradle, I get a pop up on the TaskBar, saying- Generic RNDIS (Prototype-Remember to change idVendor)
The sync then just hangs and shows the green rotating button turning but nothing happens.
I am running XP Pro SP2. on my PC, cradle is plugged directly in to USB 2 port on motherboard .XDAII has the new OS WM5 loaded, sync work fine for a while then just seemed to loose the connection, have tried to fix , by removing ActiveSync 4 and reinstalling but same problem,- Generic RNDIS (Prototype-Remember to change idVendor) What is this and how do I go about fixing this, I have also tried deleting partnership and reconnecting but now absolutely nothing connecting, can anyone help, please

I'm using Vista to flash 'PDAVIET_ROM_WM61_OS20765_ATOM_Sonblack' but I was disconnected from Windows Mobile Device Center. Now my Atom cannot reset, cannot sync and STUCK with message 'Update Utility'!
Please help me to get back my Atom!
Thank you so much!
Use rec + camera + reset button.
In DM mode choose Exit DM.
weird! it works on winXP but not in Vista!
anyone know why?
Lots of things could be causing your problem. Here are some things for you to try:
1. MOST IMPORTANT: Make sure that you plug your device directly into the computer. Do not plug the device into a USB hub or other device. If you are using a laptop, do not plug the device into USB ports in your docking station. More technically, make sure that the port you are using is a Root USB device, not a Generic USB one. This make quite a difference in Vista, because locking your computer or having a UAC prompt while you are connected to a generic USB device seems to interrupt the connection.
2. Make sure that you have "Advanced Network Funcationality" enabled.
2. Make sure that you have the latest version of ActiveSync or Windows Mobile Device Center (Vista). If you are using Vista, the current version is 6.1. This version has some updated drivers that seems to help immensely with stability.
3. If you are using Vista, make sure you have all the latest OS updates installed. There was a Windows Update sometime back in November of 2007 that fixed some serious bugs in the USB drivers in Vista.
4. If you have Windows Firewall Client for ISA installed, do a search on the Microsoft website for possible problems with interactions between ActiveSync/WMDC and the firewall client.
Hope this helps.
Problem with Rom flashing

You must be careful with connection whenever you flash your rom. Never disconnect when the process is still going on.
This is what I think you should do to try to rescue your Atom.
1. Make sure that your Atom can really communicate with your PC. As long as they show that they're connected is ok.
2. Flash that rom again. This time please make sure that there will be no disruption on the connection. Don't disconnect while the process is going on or you'll have a high chance of transforming your Atom into a toy.
You have to follow the instruction and wait until the end of the process. I've flashed many roms without any single problem.
3. You better flash using direct connection. Don't flash from your SD but directly from your PC.
Hope this helps!
Hey everybody,
I'm new to this flashing as well...
I have a Tmobile US HTC HD2...
I installed the HSPL3 after getting the Windows Mobile Device Center...
It was installed successfully, but after that whenever I connect my HTC to my PC, I can hear the ding but my PC is not recognizing my device and there is no connected icon on the HTC as well.
I tried all the USB ports and nothing worked. Without connecting my device to the PC you know you can't flash any roms as well...
Any help please...

Are you trying to do this while your screen has the three colors?
If so....does it say USB at the bottom or serial?
not while bootlegger mode. I used that for installing the hspl3.
my pc didn't discover the connected device and there was no connected symbol (which you get on your hd2 on the top right side, next to 3G n/w symbol).
when I connect, it shows that as a mass storage device on my pc and the safely remove hardware sign shows up.
I hope this explains my problem.
settings menu all settings connections usb to pc tick active sync untick 'faster data' reboot the pc, reboot the phone. Should be fine.
Thanks Sam, it worked. Unticking the 'faster data', did the trick...
Thanks again.
Hi.
Firstly, sorry about my English.
I am using HTC HD2 about 6 months. I was able to connect my phone with my pc by USB. But nowadays, i can't do it.
My PC is using Windows 7 64-bit.
Now, my problem is:
When i connect USB cable, there is no notification or sound in my PC. (like "a device connected to PC" or "a new hardware found" etc.)
Phone can be charged via USB connection with PC but I can't use activesync.
Otherwise, when i connect PC and phone by Bluetooth, i can use WMDC.
I controlled "USB to PC" module in my phone. I tried "enable faster data synchronization" checked and unchecked. And i checked "Ask me first..." But there is no effect
And also, i tried it in another PC (which is Vista) and another USB Cable.
And when i shut down the device, and i open it while pressing volume down button, bootloader opened but in bootloader screen there wasn't a text like "USB". There is a text "Serial".
I make hard reset but it doesn't effect too.
What do you think about my problem? May it be about USB input of my phone?
I used to make HSPL in my phone and he has custom rom now.
If the problem is a hardware problem, is it out of warranty? :S
Please help me.
Thanks.

It maybe because you are using Win 7 64 bit. Try installing 32 bit as well and see if it cures your problem.

Hi.
Thank you for your attention.
Unfortunately, i tried it, too. In another PC, whose OS is Vista 32-bit. There is no sound or notification at PC
Actually, i've searched so many topics in this forum.
And i am almost sure that my problem is a hardware problem.
Because i tried so many things in settings of PC and Phone but there is no change.
I just wanna ask you, guys, if i send my phone to service, is there any problem about my phone's HSPL and Custom ROM situtation??
So the problem is hardware problem and most probably my USP Port is damaged.
Do you think they tell me that "your phone is out of warranty bec. of HSPL!" ?
Thanks.
faulty cable or faulty usb port. search out the "stuck in car kit mode" thread and compare the symptoms.
As per the title, device manager doesn't change when I plug the phone in, tried two different computers and two different cables, flashed the stock firmware back, and still nothing.
It charges when I plug it in and SOMETIMES brings up the MTP-Initialization logo thing, but never gets any further.
Is my GS2 goosed yet again?
Edit: Tried on my PS3 as well and still charges, but won't ask to mount the SD card or anything, so I'm back to my trusty HTC HD2, wondering whether I should sell the GS2 once it's repaired and get a Galaxy Nexus...
Hah, another HD2 veteran, it's like everyone from the HD2 forum is now here... even the devs. Anyway, may be a stupid question, but are you always trying with the same USB cable?
Disable usb debug mode
Sent from my GT-I9100 using xda premium
Tried two different cables as stated in my OP, and it doesn't matter whether USB Debugging is on or off. I'm taking it back to the service centre after work today, and I'm probably going to sell it after.
I've had the camera go.
I've had it not vibrating at all.
I've had problems with spots on the camera lens.
I think I'm going to put some money to the sale of it, and get a Galaxy Nexus, hopefully the built quality will be at least a little better...
Solution is in the phone
Dear All
Following are my observations and possible steps to
1. When the phone is upgraded to Android 2.3.4 and above (mine is 2.3.6) Kies stops recognizing the phones and USB connection / Serial port connections etc get reset on the phone
2. Even if proper drivers are there on the laptop (mine is Windows 7 64bit) they are not recognized
3. Device Manager shows "unknown device"
4. Updating the driver also does not result in any help
5. solution lies in the phone
a. key in the dialer *#7284#
b. it has 4 option there..
UART (MODEM/PDA)
USB (MODEM/PDA)
c. For USB. select the PDA.if it already selected to PDA. reselect it by select MODEM and then PDA again.. Only change the USB setting.. andthen press back. try reconnect (thanks to napi1 @ androidforums.com/samsung-galaxy-s2-international/447145-sgs2-kies-not-syncing-os-2-3-5-a.html#post3484588)
6. The Laptop will start recognizing the required drivers and install them
also
Phone is not recognized by laptop when it is in USB debug mode, MyPhoneExplorer does not recognize when it is not in Debug mode
Hope this helps

Thank you !!!
Unbelievable! Thank you soo Much!
Helps also on Mac 10.6.8
Thanks a lot mate..I was afraid that i'll have to take it to service center. This helped me.
thanks people!...even i had upgraded to 2.3.6 and usb mode just wouldnt work....
this solved that problem though..
Fantastic tip!
It worked! Now my S2 can be detected by the PC.
Thanks a million!
Doing a factory reset after backing up data will solve the problems.
Still Hasn't worked for me. I'm getting no USB function other than Charge. Its working as if the USB isn't plugged in at all.
Is there anyway of reinstalling the MTP application on the phone? When i find it through App manager its showing with no size and no options inside (clear data or clear cache)
Kies isn't working as far as the phone is concerned there is no USB connection at all.
I know ICS is coming within a few days for GS2 owners, will this clear the problem???
So frustrating.
Thanks in advance if anybody can help

same with mine. mine still doesnt work with the dialer *#7284# and with debugging off or on. ive unistalled and reinstalled the driver serveral times and nothing and this has happened to me on my hero and my sgs2 dozens of times, its so annoying =[. at one point i manged to get all but the usb storage drivers installed. what else can i do ???
Same problem
Same problem here, tried everything (to my knowledge). Someone told me it had to do with the battery overheating because I had use the charger from another phone. For about 2 days my phone would go on vibrate randomly and started the connection process (like a usb cable was connected). It could do that non stop for a few hours. Now that Im back to my original charger, it stoped, but still can't connect to my pc.
I tried on 3 diff PCs with diff version of windows...
I've tried everythin, debug mode on/off, reinstalled Kies, drivers, did factory reset, but nothing.. when i try to connect my SGSII to Kies, it writes "Current connection mode not supported by Kies".. I'm on Lite'ning rom v2.2..
If you're running a custom rom, why would you want to use Kies ? It's awful. There are so many other apps that have the same functionality as Kies (tho granted not one app that does everything Kies does) that work perfectly with custom roms.
Only reason to use Kies would be if you went back to stock because you wanted official ICS OTA or similar IMHO.
I did a backup with Kies, now my all contacts, sms, videos, music, calendar are in this f***in' backup file.. :| I have an awfull headache Or i can do a restore with another app, will it be compatible with Kies's backup file?
same problem. USB connection to PC will only charge. Recently updated to 2.3.6.
Tricky one.
----------EDIT---------
it worked ok after rebooting my PC. Must just be general crapiness.
