not reading in download mode?

ok. so I recently started using a different computer, it's windows vista. when I go to download mode, and plug the phone in the computer just says "usb device not recognized". I've got the latest drivers, and tried uninstalling then reinstalling again. any ideas as to what is going on?

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.

Phone storage doesnt show up in windows

Ive had this issue for a few weeks now and its finally got my attention because i cant load any custom roms into storage.
Whenever i plug my phone into a computer, it will charge fine, but wont connect and show storage. It doesnt show up in device manager and usb debugging doesnt activate. Im using windows 8 and i did notice an error pop up telling me that the usb device is not recognized and has malfunctioned.
Oh, and im running ARHD 12.1

did you install the htc drivers correctly on your computer?

yeah. i had everything working fine for months before. im checking to see if its an issue with the rom. i think it first started after i installed the version that im on.

If you plug your phone in via USB, to see the internal memory, your phone needs to be unloacked. Will will come up with a warning on the the phone.
Steve

Im starting to think this is a hardware problem.
I reverted to stock and the issue is still there. Im now noticing that it shows up in device manager occasionally as an unknown device. It appears to connect and disconnect over and over on its own. Sometimes it will stay connected for a few minutes and i would try to update the drivers manually but it would say no drivers found. Windows also reports that "my device may have malfunctioned". I know that all my storage is still in tact though, so i guess its just something wrong with the usb controller?
Thank goodness for wifi file transfer or i'd have no access to my storage. But im concerned that i may be stuck if i ever need to adb or fastboot...crap!

Delete pls wrong thread

Phone won't connect to HTC Sync or adb

Got my phone about a week ago & got pretty bored of it so I wanted to root it and get a different ROM going. For some reason, I can't get the phone to connect to HTC Sync Manager though I updated the drivers. Any time the phone is switched into USB debugging, My HTC drivers fail to install. I have no idea how to solve this problem. Also when trying to get the Token ID using the command prompt, the device doesn't show up after using the command adb devices either. Need help please.

In bootloader you should type fastboot devices not adb devices.
You can try this to get the drivers installed correctly
On your PC go to device manager and find your phone(usually M7WLS), right click and select properties
Select the driver tab
Select update driver
Select browse my comp
Let me pick
Look for ADB USB device or similar should be one of the first couple choices
Select MyHTC install and you should be good
Also try these drivers http://d-h.st/FXC

If the phone doesn't have USB debugging enabled, it doesn't appear in the device manager besides under portable devices. Once USB debugging is turned on, Android devices tab appears at the top but the drop down reads My HTC with the yellow triangle with ! on the inside indicating there's some sort of issue. I tried updating the drivers, uninstalling the drivers, restarting the phone and computer, then reinstalling the drivers but nothing has worked thus far. HTC Sync still isn't detecting the phone at all and I can't get the Token ID to continue the rooting process until the device is able to be detected.

Strangely enough, I literally just tried it on a different computer and everything worked exactly as it was supposed to. I had 3 computers in my home, none of which worked but got to work and the laptop they gave me worked just fine. Then I got on my gf's Mac and it went mostly smooth (even though it was difficult not being as familiar with the OS). My advice is do everything you're doing on a different computer until you see it without the ! in the device manager.

My experience may be helpful. I had no ADB driver, but Composite USB seemed to work. However, the driver install crashed. I needed to open my phone and answer the dialogs on my phone while the driver was installing. After that, everything is hunky-dorry (I know, showing my age).

I was having the same problem until I UNCHECKED the USB debugging mode and reconnected the phone to the computer. Drivers reinstalled and HTC Sync Manager (not HTC Sync--different program) recognized the phone. I had to answer dialogue on phone and then the USB debugging mode status changed itself to enabled. It's all working now, after hours of fiddling.

Unknown USB Device (Device Descriptor Request Failed)

I am having issues with my Nexus 6. I am unable to get it to connect to any computer. Windows says the device is malfunctioning, but it charges okay. Windows gives the error "Device descriptor request has failed." It doesn't matter if I'm booted, in fastboot, or have the phone off, it gives that error.
What I have tried:
Toggled USB debugging, MTP, and PTP.
Nexus Root Toolkit to try to install the drivers
15 Second ADB Installer by Snoop05
Alternate drivers (Naked, Generic, PDA).
Each time I have tried new drivers, I have checked to uninstall anything using USBDeview.
Tried "Updating drivers"
Tried three different Windows machines.
Tried different USB cables
USB 2.0 and USB 3.0 ports
Cleared cache partition
I think I am down to two things: Factory reset or draining my battery all the way and letting the hardware reset itself. I am not confident that factory resetting it will work since this same message pops up in the bootloader.
I have researched the hell out of this and one person in this section was having similar issues but got it working when plugging it into their USB 3.0 port. If those last two things do not work, then I don't know how the hell I'm going to lock the bootloader to get it worked on--that's the only thing I have done to it as far as modification wise (/system is stock, no root).
Any help is greatly appreciated. This is so frustrating since using USB is our way of working on these damn things. If I could get root without having to use USB, then I could easily lock the bootloader back.

Does anyone know how to re-lock the bootloader without root or using USB? At least I could have it locked so I can RMA it.

In your device manager see if you see the device with a yellow exclamation mark. If so right click it properties select update driver and then choose the driver option and it will give you a list of things to select.

Doesn't work, I'm afraid. Windows says it already has the best drivers for the device. The device simply is not telling Windows what it is. Thanks for your reply.

I've come to understand that USB problems are generally Windows' fault (i.e. Windows itself or poorly written drivers) rather than the device's fault. Not always, but the vast majority of the time.
See if anything in this article helps - installing the Google USB driver worked for me:

right click the file then go to update driver than select browse my computer then at bottom select let me pick.

Thanks for your reply. However, I have a hard time thinking that three Windows machines are experiencing the same thing. I have successfully gotten it connected before the 5.0.1 update to transfer ringtones. I even booted into Linux Mint and couldn't get it to connect either. It's like the controller is bad but it can still charge.
Also, I have followed every direction on your link at least twice already.

Thanks for your suggestion. I have tried this and Windows refuses to use the proper drivers. It argues they aren't for 64-bit OS, but they have worked in the past. I almost got it to use some Samsung drivers, but after it installed, no change. The device is not reporting the details it needs to convey to the computer to start a proper driver setup.

I have not been able to connect either. Tried 2 different Nexus 6 devices, numerous reboots, different cables, different USB ports and all the stuff you tried also to know avail. I updated drivers, went through device manager, but I can connect when I switch from MTP to pictures, however you don't get the same access.

To me, it sounds like you have a glimmer of hope. Have you tried a different computer? If you don't have a different computer handy, boot Linux from a flash drive and install fastboot and adb.

Windows 8.1+Nexus 6 USB MTP-mode

IS anybody else having issue when trying connect Nexus 6 to Win 8.1 computer via MTP-mode? My laptop isn't reconizing and i'm sure that i have drivers installed. I know that this is common problem (also with OnePlus One). It's working with PTP mode but not MTP mode. So i want to know if someone have solutions to this?

Did you try it with USB Debugging off?
I ran into this with Win7, the instant i unchecked USB Debugging, MTP fired up working.

Haven't had a problem yet. I plugged mine into my computer when I got it and the phone connected almost immediately. Already had the sdk manager installed but I don't believe I installed any other drivers. I also have usb debugging turned on. Have you looked under device management to see if there are any yellow exclamation marks showing up for your nexus 6.

yes i had this happen, the solution for me was the delete the samsung ADB driver (think it was called that) in the device manager, unplug the phone, give it 30 secs then plug back in. worked after that.

That worked almost. Difference was that it was named Google ADB Driver. I deleted that, unplugged and plugged again and it installed drivers again so it was some drivers issue, not sure why. But if someone have samething just try that.

good to know it worked. it was the google ADB driver, not samsung !
