USB issues after fresh 2.0b and .03 radio plz help

I recently switched from fresh 1.1 to fresh 2.0b and also the new radio flipz came out with. I love it and I cant wait for all the bugs to be out. I do have a kinda serious problem tho and need the advice of a droid/linux guru. Why is my usb connection not working anymore. I tried it on 3 cpus and no recognization. Also I used the dev tools and it says everythings fine. Some other things I have done is wiped->flashed etc. no luck and also installed the drivers. nothin. On a side note it does charge! thanks alot any advice would help!!!

When you say your USB doesn't work, what exactly do you mean? Do you mean that your device is no longer recognized?
If that is the case, try this (also, make sure usb debugging is enabled):
I have win 7 64 and here is what worked for me:
1. Uninstall HTC Driver (this will likely give you an error, you can ignore it)
2. Uninstall HTC Sync
3. Download and install PdaNet
4. Follow the directions when installing PdaNet

Yea basically the phone is connected cia usb cable. by using the app" dev tools" i can tell the phone and computer are communicating with each other but no notification by windows or phone and they will not Activsync, htc sync, or mount. Also if you boot to recovery it will add files. really odd but it seems to be a problem with alot of ppl. Preciate it im trying what u said right now I will post with results.

turn on USB debugging

USB debugging is most definitley on. I double triple check it every time. The uninstallation of htc sync and driver and the install of the pdanet did not work everything was fine until 2.1 and the radio. But I did wipe and reflash a second time

bump still strugglin comin guys someone has to have the answer

well the radio should have NOTHING to do with connecting via usb... try nand-ing back to a 1.5 and see if you can connect through adb again.. my $0.02

I have the same problem and I am using damage 1.0...The problem is that it no longer gives me any options when i plug in to my computer. I have been working on this for a few days, it really sucks cuz i don't have any other roms on my memcard so I am kinda screwed if I can't figure this out...maybe i will just wipe and start over. I am 100% sure this is not related to the radio whatsoever. Does anyone know how to change the default for when u plug into a computer...i have tried just going to settings/connect to pc. Ask me is checked, and disk drive is default. I am wondering if there is a default to clear in apps management.

well if you are using disk drive you need to use usb ports build into the mobo. idk why but any usb that is not built in will give you problems. even on my laptop the usb ports that are plugged into the mobo dont work but the ones built in do. try that.

I am not sure what u mean by mobo? but it worked on the same usb's when i first flashed, i typically use the exact same usb for everything...i have 4 ports built into my laptop and none of them work for the phone. i even tried reinstalling drivers and htc sync...idk, i just wiped, and then restored and still no go, i guess i will try a wipe w/o restore.

If you're on a desktop, he means plug the cable into the USB ports on the back of the computer chassis. The USB ports there are soldered directly onto the motherboard, where as USB ports on the computer chassis are connected by a cable to the USB headers on the motherboard. What he's saying is that the cable could've been damaged/fried/came loose, so try the ones in the back.

OiC, that isn't the problem I have tried multiple ports on all of my computers(all laptops) as well as multiple cords...idk FML, just reflashed will see if it works.

ok so i just wiped and reflashed, now i am stuck at the X loading screen and the phone is frozen...FML, is it bricked, i can still get into recovery, i have the old fresh 1.1 ROM on my card, should i just flash that, or should i just use the nandroid backup i made from stock?

ok so flashed back to stock and my computer still won't recognize my phone...any other ideas, it has to be the computer right?

unless your phone won't charge plugged into the wall (meaning it's your phone), then yes.

Did u check with changing the cord ??
I had a similar problem after upgrading radio & fresh 2.0b. I just changed the USB cable and it worked fine. Even now it doesnt yet work with the earlier cable. Something went wrong in that front, but a diff usb cable did the trick for me. try it out

i have changed 5 cords. have messed with every setting known to man after doing so wiped and reflashed. everything i have used every usb port 1.0 and 2.0 and my phone most definitly charges ( my phones never been so charged) i am a comp prog going on my mis degree im pretty good at this and know my stuff Im just wonndering 2 things is it phone or cpu? reason I keep being so indecisive is because comp will recognize a device when it is in heroc but wont verify its a hero( ive tried all drivers) but phone connected fine b4 2.0 i duno im all out of ideas im gonna try to install the new heroc .6 and hope for the best thanks for the input guys!!!

[Q] Can't connect my Captivate through USB anymore

Hi everyone,
I'm having issues connecting my Samsung Captivate to my computer. For about a week, it worked fine, I was able to transfer files to my phone but recently I noticed that the "USB connected" notification is not showing on the phone when plugged in to the computer.
Now, when I plug in my phone to the computer it just charges but doesn't comunicate with my computer. A friend of mine bought the same phone right after I did and he gets the "USB connected" connected when he plugs in his.
I tried using his USB cable but again, the phone is not recognized by Windows nor the phone detects it is connected to the computer. I've tried installing several USB drivers that I've come across on several forums, but nothing. I even downloaded and updated Kies to the latest version, but still nothing.
My phone is unlocked and NOT rooted, and I'm using Windows 7 x64. I've set the USB Settings to Mass Storage, even to Ask on Connection, but it doesn't ask anything when I connect the phone to a USB on my computer.
Sometimes Windows knows there is a device connected but says it couldn't recognize it.
I already did a factory reset, but the issue was not solved. I've tried connecting it to other computers, but still hasn't been able to connect my phone correctly.
What could it be?
Thanks!

Hmm. You have Mass Storage selected and up-to-date USB drivers. Try selecting USB-Debugging and Stay Awake in the Development option of your phone. If that doesn't fix it, then I have a few other ideas.

Make sure the usb door is completely open, it should click into place, some users have reported this solves their usb issues.

I did what you told me, but still my phone ain't recognized by Windows nor my phone is aware that it has been conected to a computer
What other ideas do you have in mind?

Have you tried using a different USB outlet on your computer? I had this same issue when I plugged my phone up using the USB outlet on the front of my computer then when I tried the one on the back of my computer it worked just fine.

Are you running a launcher app? I use launcher pro and can't connect until I change back to the default launcher with home switcher and launch it.

First off, think back. If it worked for a week and then suddenly stopped, what changed? Maybe you updated something on Windows or changed something on your phone. There's a reason it just stopped.
You can try using a free program called USBDeview.
It might do the trick for you and help you install the correct drivers. I'm thinking you no longer have them.
1. Download USBDeview (link is above)
2. Plug your phone in and open the program. Find all the HTC drivers-delete them
3. Unplug your phone and plug it back in
4. The correct drivers should install automatically
You can also try updating the drivers manually.
Galaxy S drivers (These are for ADB, but will work fine)
1. Click the Start Menu on your computer and right click "Computer"
2. Choose "Manage" --> it will ask you to continue --> "Device Manager"
3. Plug you phone in and look for it to pop up, probably under Portable Devices
4. Right click --> "Properties" --> "Update Driver" --> "Browse" --> "Let Me Pick" --> and navigate to the location you extracted the drivers to.
This is most likely a driver issue. I doubt your phone is messed up. You'll get it eventually. I also had a hard time getting my Captivate to connect. After uninstalling and reinstalling my drivers (more than once) it finally worked. One last thing, for now. When you uninstall drivers, also make sure you don't have any installed under your program list. As in, Control Panel --> Uninstall a program. Good luck!

A friend of mine, who bought the same phone on the same day as I did, plugged in his phone on my computer using my cable to the same port my phone was connected, and he did get the "USB Connected" notification on his phone

I did all that yesterday, but the device ain't listed in the USBDeview nor it shows up in the Device Manager

did you finally fix this problem? because I'm having the same issue here

Same here. It was working fine, I could connect to Kies, transfer music in Media mode and see both sd drives in Mass Storage mode. Then I rooted today and now I get nothing. In anything but Kies mode I get the Windows Bong of Recognition, but still not visible in Explorer. Also, my Home screen stays active instead of switching to the USB animation like it did before. I know this can't be a consequence of rooting the phone, can it?
EDIT: More weirdness, with the phone connected in Mass Storage mode if I look at My Computer in Explorer there are 2 extra drives showing, but they are greyed out and when I click on either of them it asks me to insert a card as the drive is empty. WTF???

UPDATE: I unrooted and managed to get my USB connection back to working. It is still a bit flaky as I sometimes have to disconnect/reconnect several times before it works, but at least it now works although it sometimes loses sync in the middle of transferring a file. Can't imagine why simply rooting the phone would cause the loss of USB connectivity. I am going to reroot and see if it occurs again.

OK, a rerooted the phone and this problem is now back. I have no problem connecting while in debugging mode. I installed OCD (non-Market apps mod) and when I turn off debugging and connect I get the Windows bong and see the USB icon in the Notification bar, but the MTP screen never comes up and I can't see the phone in Explorer (Mass Storage mode) or in WMP (Media mode). Kies can;t see it in that mode, either. I really don't want to have to unroot every time I want to look at the phone contents. Any ideas? PLEASE!

I'm having a similar problem - I installed the Perception ROM and immediately afterwards I can't see the USB connection at all from my PC or my Mac. The USB icon on the phone does not come up either.
I'm trying to get my hands on a different cable - but the weird thing is when I plug the USB into my computer the phone starts charging for like half a second and then stops.
This is really annoying. I tried changing the rom to Cognition 3.02 but that didn't change anything.

There are a few topics on this here on the forum - I would recommend the following:
How are you rooting your phones? Nobody has said exactly how they are doing this. Are you using recommended rooting methods? Or are you using some app found on the market?
Make sure you have USB De-Bugging is turned on.
Make sure you have it listed as ask on connection.
For those who can see the drives in Windows...
Plug in your phone and then pull down your notification bar and click on the USB connected message. It will give you an option there to mount your SDCard(s) to Windows allowing you to transfer files.
Kies is junk - I'd recommend uninstalling it as it seems to cause more issues then it solves.
Use the drivers I have posted in the Q&A section (these are the ones that are linked in Design Gears Odin 1 Click Back to Stock post btw) - but I would try and COMPLETELY removing the pre-existing drivers before installing the new ones.
Make sure the USB Cable is plugged into the back USB port that is directly on your motherboard - this will ensure it's not a computer/hardware related issue.
I know of one user who had to go through his computer and manually remove all remnants of other drivers. I have my phone connected to both a Windows XP 32bit and a Windows 764bit systems and have been lucky to not have any USB issues.
If none of that works - I'd suggest taking it to your nearest AT&T/Rodgers shop and see if they can get the phone to connect (make sure it's back to stock!). If not they should warranty replace the device.

This isn't my first rodeo... But to answer your questions:
I used the rooting method posted in XDA forums - the one-click rooting.
I've used the drivers included in the xda-forum. Not the kies software.
The only thing that changed was the loading of a new custom rom. The cable works (confirmed on my friend's phone). I can't get odin to restore back to stock because I can't get the computer to recognize the phone in either normal or in download mode. I've restored to stock using the jh7 in the stickied q&a thread
I don't think it's a hardware issue either - I think it's software-based. I'm going to try to take it to an at&t store today at lunch to see what they say.

I also have that problem only I noticed it when I cleared the dalvik cache. It messed up the auto rotate so it was always sideways and now I have no connectivity to the PC. Let me know how ATT treats you.

USB Driver issues

I've been having USB driver issues for a while now with my captivate (On serendipity 4.2 right now, finally decided to try to get to the root of this issue and update); I've used the SAMSUNG_USB_Driver_for_Mobile_Phones_x86.exe (and I am on 32 bit Windows XP SP3), and have always received a "USB Device has malfunctioned" message whenever I have tried to plug my Captivate in.
My computer has 2 USB Ports; one of them has a USB 1.0 hub plugged in (which has a keyboard & Plantronics Microphone plugged in as well) and the other has a Logitech mouse. I've tried both of the main USB ports, as well as the hub. The hub's been plugged in when installing and uninstalling (I'm trying to give as many details as possible in the hopes that one of these might trigger a red flag).
Anybody know what the problem might be? Maybe I've been uninstalling the drivers incorrectly? (I've done it through device manager & restarting the computer before reinstalling)
EDIT: No Kies on this computer, has never been installed; I have been mounting the device via the notifications menu but it still gives me a malfunction error.

Hmmm.. You've done everything that I would try as well...
At this stage I can't really say it's anything specific... Have you tried it on any other computers by any chance? Or got it working before?

Should mention that I got it working by turning on USB Debugging mode on after installing the drivers, then plugging the device in, and after that it began to function as normally.

So is it working now or not? Sorry, the latest post is a bit confusing...

I think that's a known issue. I usually can not get my computer to recognize my captivate without enabling debugging

[Q] Connecting to computer problems

Hi all!
I have a Nexus One running CM7.2.0 with Clockworkmod Recovery. My computer is running Windows 7.
I want to connect my phone to the computer in order to return it to it's factory state with an official shipping rom and stock recovery image.
However, I've run into a problem which I've been having for quite a while now; when I plug the phone into the computer via USB cable, it charges, but nothing happens on the computer, and nothing happens on the phone.
I've tried different USB cables, and different computers.
If I push the part that goes into the phone port to the right, the computer will make a noise as if to say that something is connected, but then it will be unable to install the correct drivers, and will say "USB Device not recognized" It comes up as an "Unspecified" device in Devices and Printers, and in "Unknown Device Properties" it tells me that "Windows has stopped this device because it has reported problems. (Code 43)".
I have a feeling that the problem is the port on the phone, but I wanted to ask on here first to see what other people thought. Why is it that the phone charges correctly, but won't be recognized on the computer?
I might just add that this problem first started when I installed a device manager program that allowed me to see my texts and things when the phone was plugged into the computer. It was a while ago, and I think I remember (not entirely sure though!) not safely ejecting the phone before unplugging it, and then 2 minutes later when I went to plug it back in, this occurred. Whether this is related to the problem or not I do not know.
Also, I'll add that this problem has been occurring for quite a few months now, but it is only recently that I have noticed that when plugged into a wall charger, the phone charges much slower than it used to, and the charging light will go on and off every so often. This suggests port wear, but this started happening quite a while after the connection problems happened.
Anyway, thanks to all those who respond! I am keen to work out what is wrong.
Thanks,
Simon

Also I'll add that the SD card works perfectly fine in an SD card reader USB thing!

My phone doesn't work on any computer I try it on. All other USB devices work fine on the computer I am currently using. This means that it is not simply a matter of following the steps you linked, because the problem is not related to a windows error.

I've been working with another member on this issue. Go here and read through my suggestions and see if one helps. The first thing I would try, is to uninstall sync manager and all drivers for the phone from your pc. Then, connect the phone and see if it reinstalls sync and the drivers. I hope this helps.

usb 2.0 . i have two friends with htc one's and they both connect just fine.

Same issue here! Last night pulled my phone out and it said "incompatible charger, please use original charger". I wasn't even charging the phone, and now it wont charge or connect to PC unless the phone is off. Tried turning off debug/developer/power save/fastboot/ etc with no luck so far.
