My Mini XDA can't connect to my PC via USB cable anymore, it can only recharge the battery.
My iPaq connects flawlessly, so it's not my PC.
Any suggestion ???
Mine does not connect after been run even a little bit. However if I do a soft reset and connect to the usb cable it seems to hook up right away. Whe I first got it it did not have any problems like this and I would like to fix it if possible.
I get a rather frustrating mesaage when I connect my O2 Exec via the USB port. It takes about 3 time before the connection with the comp finally happen.
The message is - 'USB Device not recognised' ' One of the USB devices has malfunctioned ........'.
Does anybody else have this problem and can anybody help?
Yep
I get the same problem but only with one PC. It happens on either USB port and is not helped by adding a USB hub. As such i am investigating the problem as if it is PC based.
Is this with ActiveSync or CardExport? Either way try rebooting PC first, wait for it to finish loading Windows. Power off your Universal, connect cable to Universal and PC then power on Universal. Seems to work okay for me. If you are using CardExport, remember you can't change modes while connected.
Regards
I have an O2 xda mini and that connects first time every time.
Found it strange that the Exec did not do same!
I have this on one PC - make sure the XDA is turned off first. Then plug the USB cable in and it should power up by itself and get recognised by the PC.
Also make sure you are using the very latest ActivSync (4.1 I believe).
Thanks lads - connect the cable while the Exec was off and it cobnnects first time. Good stuff!!
Why is that?
I think its the phone not the pc that is at fault, as i had a usb car charger and a usb power charger, both using a standard usb lead and the same fault applies, obviously just charging, AS wouldnt happen would it lol.
me missus just got a wizard and none of these faults occur on it
I concur that the plugging in USB while Uni is switched off is much more successful. Can I check with you guys - can you activesync by USB while bluetooth is on? I've not been successful with that.

Hi,
I am using QtekS200 G4 .When I connect to the USB in one of the pcs where Activesync 4.5 is intalled I am able to sync once or twice after which I get this error in PC USB device not recognized.I am not able to connect to PC then on.I tried reinstall ActiveSync...Rebooted etc...The problem persists.
try another USB cable or try it with other device,
I had this problem with my friend PC, and it was his USB cable, hope it is the cable, the cheapest thing to replace
but my advice try the qtek aku 2.2 ROM with SPL 2.20, it has nothing to do with this but it is for your device
The device is charging via the USB...Anyways....Let me see...When I reboot the Qtek it connects and i am able to sync....Once I disconnect after this and connect the problem crops up...
it maybe your PC, try with another PC, and please update to last bios for you mother. it maybe your PC, I'm not sure.
and it could be your phone, but I don;t think so,
do you have SP2 if you use windows XP, try to have SP2, it has a lot of fixing for USB driver.
by the way, USB cable has 4 wires, 2 for electricity and 2 for data transfer, charging doesn't mean it is not defective.
Problem Solved.....I have two USB good condition USB cables though .......A hard reset did the trick.......
great, I would say it is your computer, casue when restarting the computer fix the problem
good it is working now
I tried rebooting the pc....reinstalling activ sync.....soft reset.......Everything failed to work......Hard reset did the wonder otherwise I would have to sync via bluetooth forever .....Before purchasing any hardware i suggest a hard reset for any nagging issues....
Hi,
I have for two days tried getting my PC to recognize my SGS2. With no luck. I want to ROOT my phone.
I am using Windows 7 64-bit and gingerbread v2.3.5
- USB-debugging is turned OFF.
- I have tried to format the SD-card, even used different SD-cards.
- I have tried using another PC, with no luck.
- Tried diffrent versions of Kies; 1.5, 2.0, and 2.1
- Tried diffrent versions of the Samsung Mobile driver; 1.3 and 1.4.8
- Tried using a different USB-cable (the one I'm using, is original and i can see that my phone is charging.)
- I have formatted the phone several times.
- I have tried typing *#7284# and changes the USB setting from Modem -> PDA
- Windows Drivers are up-to-date.
- I cannot see anything in the Device manager.
What else is there to do? Is something wrong with my phone?
Is there any APK, besides from Gingerbreak, that i can use to root my phone?
Cheers
Could you tried it in another PC with Windows XP?
When you plug it in to the USB port... Does the phone start to charge up?
Sounds like a hardware issue, i too have Windows 7 X64 on my laptop and no such problems.
Give a shot with USB debugging to ON.

I had the same problem.
This may sound stupid, but it does work, try another USB port.
I just plugged my USB cable into either one of the front USB ports on my PC (WinXP) and sometimes the phone connected (Debugging ON: phone was an external hard drive. Debugging OFF: phone connected to KIES) and other times it didn't. I tried toggling the Debugging, switching off and on the phone, changing USB cables, uninstalling KIES and then reinstalling KIES.
I finally noticed that the phone worked fine on the front left USB port and not on the front right. I have the same thing happening on my work's PC (only it was the front right port that worked). The rear USB ports didn't work.
I doubt that it is a problem with the PC operating system (I found out later that someone with a Mac had the same problem). It therefore must be with the phone's software recognising a connection with a computer and only wanting to connect through that initial connection port.

ive noticed this problem too of it only working with certain usb ports and not others on the same pc. Quite annoying when i was trying to use my phone to transfer some files from another computer and the phone wasnt picked up by the computer.
I think it may have something to do with using MTP rather than standard USB mass storage.
Never plug your phone or any other usb powered device into your front USB ports. most of them do not supply full power. As a matter of practice you should always plug your phone into a direct motherboard USB port on the back of your computer.
I had the same problem with my front ports several times on several computers. My first galaxy S1 would not work on my front port either. all problems were solved by plugging into the direct motherboard usb ports.
Why would you turn USB debugging off?

Do you have Administrator rights?
try installing drivers manually on your pc
and then plug the phone ( usb debugging off )
Try 32bit system
Try using a 32bit XP or 7 PC someone I know had the same problem their Win 7 never gave the problem when flashing or connection with their SGS2 for over 6 months. And just the other day they had a problem so they used a XP 32 bit PC connect ok flashed ok once the phone was rebooted they connect to their Win 7 64bit and the PC saw their handset. So what gives

I have plugged in many different phones and other devices that take their power from the Front USB ports on my PC. Power has never been a problem. Recognising a device can sometimes be a problem (but the same problem happens with the rear USB ports).
I regularly charge my SGSII via the Front USB port of my PC (both work and home). Quite a few of my workmates now do the same because a spare microUSB cable is much cheaper than a good mains charger and also they can back up their phone and transfer files as well.
This worked for me
1. Unplug the USB cable
2. On the cell phone, dial the following number: *#7284# Once the last # is hit, the PhoneUtil application is launched. Choose USB -> Modem and then USB -> PDA mode. The good mode should be PDA. Even if the mode is PDA, switch to Modem and then back to PDA.
3. Plug the USB cable.
Sometimes if you're not using the cord that came with the phone it won't recognize the phone
I had the same problem with my phone but I found the cord the phone came with and it solved the problem

Try turning off your antivirus first for drivers to install. Worked for me.

I have just installed SiyahKernel 2.3 and Windows 7 Ultimate 64 bits did not recognize my SGS2.
What I did is turn on and then turn off the "USB debug" option. It was off at the beginning but... I did that just in case and...
That solved my problem.
Similar issue
My phone charges when plugged in but won't mount. It worked fine until about a month ago.
I'd similar problem.
My SGS2 couldn't be connected to PC (Windows 7 Ultimate 64bit) by USB cable, but it could be connected via Wi-Fi. I found out, that my, however original, USB cable was faulty (could only supply a juice from USB port ). When I used my wife's cable (she's got SGS2 too), everything was fine: my phone connected to PC, Kies v.2.1.0.11112_41 checked firmware and wanted to update, but couldn't do it, because battery was almost flat - I'm charging it now.
Will see tomorrow, however I was able to connect SGS2 to PC via USB cable
Still having the recognition problem, however you can get around it a number if ways. Use Kies wifi to get files to your phone. Use mobile Odin to flash.
Highly recommend to pay the $2 for pro version, that way it will stay rooted.

Hi im new here
I got my hd2 when it first came out running winmo 6.5 now i just cant connect it to the computer tried more than 1 computer and more than one cable when i connect it only charges i receive nothing on the computer like i used to before i have tried everything in the setting usb to pc still same thing
please help me how can i connect it
and i also tried hard resetting it more than once same thing
under settings tab -----other , there will be a usb to pc button
I bet you have tried all setting changes so since you have done a hard reset and it still doesnt work, it has to be your micro USB cable. I had the exact same problem as yours and i feared that it was the micro USB port that was faulty. But then i tried a different micro USB cable and it works perfectly. Hence, it is likely to be your cable. Im not bad mouthing HTC because of the amazing work they have done, but their accesories seem to be a bit down on quality. My original micro USB cable is now frayed and almost severed, my Touch HD micro USB is also frayed and the original earpiece is now experiencing audio balance issues.
the thing is the cable that comes with the hd2 i lost it but when i was using it i could connect
but now im using nexus one cable and Nokia n900 cable to connect to the computer and it just charges like i said nothing appears
Have you tired different ports in your computer or tried reinstalling the drivers? To do that, uninstall the Activesync or Windows Mobile Device Center in your PC and reinstall it. Then try. If you still cannot connect your HD2 to the PC for USB mode, then im afraid the micro USB port in your HD2 is faulty. Try the above. Meanwhile, use the SD card method for flashing or transfer files using wi-fi or bluetooth.
Good Luck
If your HD2's USB port doesn't work you can connect to ActiveSync via bluetooth. I do that very often for a quick synchronization, and since HD2 has an Activesync profile it's easy to configure...
Anyway, check that "accept USB connections" option is selected in your pc ActiveSync configuration.
Most probably, he's facing the da** usb port breaking issue.
