Try uninstall again.
Dl usb drivers but dont install. Save them to desktop
Plug in phone
Unknown device pops up, click on message. Click install custom drivers, navigate to where you saved uninstalled drivers are. Select
This has worked for some
CM7
Ok I uninstalled any versions of the drivers, when I plugged in my phone, the computer said unknown device as usual but it is automatically installing an "unknown device" driver. When I went to select the driver manually for it, it told me that there was no need to update and it didn't give me another option.
I should probably mention that originally, the computer recognized my internal sdcard when i mounted it. Now it isn't, and it won't recognize it in any mode.

what rom are you using now? does the driver you installed came from the stock eclair or froyo. I get the same message after flashing from stock to custom roms. I just plug my phone again and the pc automatically searches and installs driver from gt i900 driver. My old PC is running win xp with android sdk manager in it aside from the kies mini it has which already has the samsung drivers which supports stock roms.
definitely wrong drivers...If your computer recognize it in normal mode as in to mount internal sd card, but says unknown device in download mode than try to download USB drivers from somewhere else...
I have noticed this that drivers from samsung website doesnt support the download mode...I have faced this problem...mine would ask for gadget serial..so i use this drivers...http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x86.shtml
Hope this helps
I'm running perception 10.4. I've tried several different download sources, and it doesn't read when I mount the sd card anymore. On my windows 7 computer it worked no matter what rom I had, and I didn't have to change drivers at all. I'll try that link and see what happens
Still won't work...
This happens to me all the time when attempting to flash back to stock. What I do is just keep doing battery pulls and switching usb ports. Eventually, it works!

lol How long will that usually take until it works..
I've tried pulling the battery and switching ports at least 15 times.. nothing happens. windows installs an "unknown driver" automatically, and if I choose the galaxy s drivers for it, it says the driver isn't compatible for my device. It's not even recognizing it's a phone, or a mass storage device, or any other usb device it can be.
Unknown Device
Was this ever resolved? I have the same problem. Unknown Device in Download Mode. ADB works, PC recognizes phone in normal mode.
The phone shows up in Device Manager when in normal mode. If I use ADB to reboot download, the PC immediately drops the phone and displays unknown device in device manager.
Have tried complete uninstall/reinstall of drivers including regedit. NO JOY.
Running XP SP3. Any ideas?
after upgrading to gingerbread my pc thinks it is an i9000.
try those drivers.
i have no issues though.
I'm getting this error when i connect my phone after installing kies. Same thing happens with the drivers from the all in one toolkit. Using only the drivers windows installs seems to let me use mtp. However, I can't access usb debugging this way. Any help?
I've been able to install the 9k drivers and the normal usb drivers however I can not get my PC to see the USB MODEM and install drivers when I plug it in. Please help. I've tried serial mode, and it still won't recognize.

also having troubles installing drivers... are u on windows 8. im using 8 and cant seem to get them working. anyone?
I have this problem in connecting my Lenovo A7000 with my laptop, whenever I connect the device to the laptop I get this error - "USB device you connected to this computer malfunctioned".
I read some other threads regarding the same error,
So far I have done these things to debug this -
1. Uninstalled USB drivers from my laptop
2. Checked for any available update for the device drivers in device manager.
3. Tried installing drivers manually using Lenovo tool.
4. Wiped data from the device to give a fresh start
5. Changed the USB cable.
6. Even tried this on other PC.
But still I haven't come across any solution yet, I want to flash some zip's in my device using the recovery, but can't install TWRP, because I can't connect with PC, so I am stuck with stock recovery
P.S - My device is rooted.
Try installing proper vcom drivers.btw a specific edition of win10 didnt detects the device.i have faced the same.
Hallo Everybody,
I'm new to flashing/rooting/etc. on mobile android devices, but since my Motorola RAZR I is stuck at the red Motorola logo, it is time to gather some experiance.
As said, the phone stucks at the Motorola logo, propably a bootloop. Fastboot access is possible, it is also possible to get into the recovery menu. But when I try to connect adb via the recovery menu option "apply update via usb" my PC (Win7) gets an "Unknown Device" in the Device Manager under USB-Controller.
I used adb before for playing a little bit around, so all Motorola drivers for the normal debug mode work, but I don't find a driver for the "Unknown Device" (recovery mode adb).
I already tried different USB cables and restarted my PC serveral times, but still no driver for the "Unknown Device". I also tried the Intel Driver update for android devices and forced to install the Motorola drivers for this "Unknown Device" but nothing helps.
I wanted to try to download/backup some files from the internal storage. Afterwards, I want to flash a lineageOS.
I also searched a day in the internet and in this forum but I didn't find a solution. Sorry if I didn't find the Solution-Thread.
Has somebody an Idea?
Many Thanks in advance.
