Intermittent "Device Not Recognized"

Hi
I have an Orange SPV M5000 with the original rom installed. However, on average every 3 out of 4 times I connect the device to my computer a balloon pops up saying "USB Device Not Recognized" and the device does nto synchronize. However if I continuously unplug and plug the device back in every 10 seconds, eventuallly it will work. I have ActiveSync 4.1 and Windows XP Pro SP2 installed on my computer.
Is there any way I can fix this problem or is there something wrong with my PC, rom or hardware? I notice that when I plug the usb into the device the charge light comes on, but sometimes will go out again just after 2 or 3 seconds and not come back on.
Many thanks
Ash

I find less errors by connecting the device with it initially switched OFF.
But really, activesync sucks.

I agree with belfast-biker. Make sure when you plug it in that the HTC Universal is OFF. If you do plug it while it is ON, just press the power button to turn it OFF and wait a minute or two then press it again to turn it ON. Your computer will now recognize your device.

Now this particular problem of yours, I have not encountered. In my EXEC, if I plug mine while it is ON, I will get the message "Device not recognize", but my EXEC would still charge, indicated by the orange light and it won't turn to green untill fully charge. But the light is always ON as long as it is connected to my computer.

Totally agree - I also find that I have less problems (not that it's gone away totally) now that I have switched off the "Turn off device if not used for"... in the Power | Advanced tab.
Cheers,
Steve.

spv m5000
I have the same issue.
Wonder if this is M5000 ROM Only? any O2 machines ?

Same problem with O2 Exec...

Same problem with jasjar, and if you check the backlight sometimes turns on without any apparent reason... I think it's beacause stuff in the notification queue...

I had this problem with my Exec and I just reinstalled ActiveSync over itself and it hasn't happened since.

My Hermes does not power on :(

SITUATION
My Cingular 8500 does not power on. I have tried connecting it to wall charger as well as USB cable. The red or the orange light also does not come on. I tried all resets also but nothing worked.
BACKGROUND
a. My phone suddenly went off when I was opening the sliding keyboard. It had a decent (60%) charge at that time. After this it refuses to come on.
b. Only addition to the phone in the last 3 months has been a 2GB MicroSd Card. I inserted this card 4 days back and it was working fine.
c. The device is around 6 months old (but its unlocked, running WM6 and does not have any warranty)
d. I have been using the original wall charger to charge this phone regularly.
HELP REQUIRED
1. Is there a way to check if the problem is with the battery or with the phone? I do not have a spare battery.
2. Should any light come on if I connect the phone to charger without the battery inserted in it?
Thanks!

Try this:
1.) Remove battery
2.) Connect Hermes to charger or USB
3.) Insert the battery while Hermes is connected to charger
4.) Red light should turn Amber
5.) Soft Reset

i have the same situation going on ... except with mine the screen faded out...it came back on once...and faded out again and will not turn back on.. when i put it on the charger it was a red light.. and will not turn on or soft reset, or enter bootloader or hard reset. .. in addition i tried the method above and nothing has worked.... any other suggestions...my phone was working fine when this happened out of nowhere... i dont have insurance either i bought the phone from someone off of craigslist..help is greatly appreciated

I am having the exact same problem, I had about 30% charge, then it just shut off, and now will not come back on under its own power or via USB nor charger. I tried connecting the charger then inserting the battery, but I do not get any indicator lights at all.
I was running WM6, and the most recent thing installed was the pointUI home screen replacement app.
has anyone experienced this before?

It wont power on threw charger without a "good" battery plugged in.
Sounds like u might have a bad battery. Happend to a friend of mine "different phone" just go to a local Radioshack If they have your type of battery and have one in stock they will most likely let you try one on your phone. If not just go to ATT wireless store and see if they have one you can try and buy.

Dear demo23019, I am not sure if I understand the above correctly. Should the Power LED light up "red" when battery is not inserted?
Once I connect the phone to charger (wall or USB), without the battery inserted in it, no red light comes on.
Does this mean that there is some problem with the phone hardware?

Yea the power LED should light up red with out a battery plugged in. Check the usb plug on the bottom of your phone, make sure the middle piece inside is still there and didnt break off.

Oops. My phone's power LED does not light up when I connect it to the charger without the battery inserted in it.
I have checked the following :
a. usb plug is fine (I checked it by plugging it into the Y cable for the USB charger. The LED on the Y cable lights up when I connect the USB plug into it
b. The middle piece inside the socket at the bottom of the phone is still there and shows no signs of damage.
c. The wall charger is also working fine.
Does this conclude that the phone has a hardware fault and this is not linked to the battery being dead?

Similar Problems
I just had the same problem. I had it happen to my Att Tilt and then to my cingular 8525. You should check out this thread and maybe post your info there too, it would be nice to see everybody post in the same thread so we can figure out what's going on.

yh
yh i got the same problem, i touched the power button so it wld go into standby, and it then refused to turn back on, even when i soft resetted it. Plugged it into the wall charger without the battery and there is no red power light coming on.
I've got a MDA Vario II and though im gettin a replacement, it kinda sucks as it seems im gna lose all my data

can we try to determine in more detail what people installed before they experienced this?

I just pulled it apart, and cleaned the inside to no avail, nothing seems to be awry, atleast not to my untrained eye, however it did get me thinking.
I listen to music on my tytn all the time, and over time the usb connector has become quite loose, frequently losing connections over activesync and music comes and goes from both lef and right. if the USB connector is shot, then when I plug it in it won't register that there is power, nor will it have the power to light up the red light indicating there is no battery. also, if the usb link is shot, then the phone wasn't charging so my battery is likely dead.
now to test this out I need to have a verified 100% charged battery.

I currently have the same problem. It will not charge via wall/usb. It flashes red once and that's it. Without the battery and plugged in, I get a solid red light. I tried plugging it into the wall charger without a battery and then putting my battery back in. The red light just turns off. That's it. I can get an active sync connection with a dim white screen, but I do not have enough juice to try flashing a new rom. If anyone has issues like these, are you also able to get an activesync connection?
TIA
EDIT: Is it possible to bypass the low battery protection when flashing a rom? My battery is somewhere around 40% so it would be safe.

Update:
Okay, I purchased a new oem battery and a battery charging dock. This way I can charge the battery without the phone before I attempt to flash a new rom.
I still would appreciate it if anyone who has seen these symptoms (white screen BUT with lots of vibrating / no charging / no bootloader) could give me a few pointers. I've exhausted the Wiki and so far it seems my only option to save the phone is to flash a new rom. Thanks in advance to anyone willing to give me some advice.

Phone no longer charges from PC USB

Hi
Yes I know its better to charge from the wall than from my PC however... Phone charges with no problem from wall outlet but when plugged into computer (for active sync reasons etc..) the battery icon stays the same and does not indicate charging. It used to work fine and I just used to leave it overnight so it would be ready to take to work the following day but not anymore.
Anyone come across this one before?
Tia
D.

Have you checked the setting under Settings --> System --> Power?

Thanks [email protected] you hit the nail on the head.
Think I know how this one happened too.. sometimes when I have been on a call I go to end it and the power screen has been on. I must have accidentally ticked the box with my face
Thank you for a very speedy response.

lol hahaha

HD2 does not sleep when connected to usb

Is there any way to have the HD2 sleep after it's been idle for a couple minutes? When not connected to usb, it sleeps fine after the configured time, but on usb, it never goes to sleep. The screen only dims.

I think, by default, the screen will stay on for 30 minutes when connected to power.

this settings doesn't help?

Well i think this is more a feature than a bug... Imagine you are transferring big amounts of data to your SD-Card via USB and the HD2 would go to sleep, the SD would disappear and datatransfer would be stopped. The same would happen while you are syncing your device...

Agreed. I guess thats just how the HD2 is. Maybe I'll just charge it on the regular wall charger.

that's not to say you can't decrease this time or just press the power button when ya plug it in 2 turn off the screen.

this was the answer i was thinking about
or, are you saying it powers off fine when connected to a wall charger and acts differently if connected to a usb data cable?

That's it. And it's normal, as when connected to a computer it's either for activesync, disk drive or internet sharing, and in any of these cases you wouldn't want it to go to standby randomly, so it doesn't.
Just press the power button.

I'm interested too.
If I press the power button in my Leo while connected to my PC via USB, it sleeps, but then it turns on again.

No power, red LED blinks now and again, otherwise nothing

Recently I noticed that my S8 was not fast charging when plugged into the wall outlet, but it was still at least charging albeit slowly. Yesterday the battery was down to 15%, I used a car charger on the way home, not really paying much attention to the battery percentage, but then when home used it for a couple minutes before plugging it onto the wall charger.
At that time I noticed it had shut off, figuring the battery was simply flat I left it for the night.
This morning I get up and it is unresponsive, if I push any buttons the LED will blink red a couple times then do nothing. I have tried to reset holding the power button and volume down and just get the same red LED blinking. Tried plugging it into a laptop charger, and still nothing.
Any suggestions before I send the thing back? Any way to access the pictures, contacts etc?
Thanks.

Laptop and car chargers are usually slow. Do get a new home charger with cable and even change the socket which you use to plug the charger in.

I have a smilar problem.
100% battery, charged overnight, at 9:00 the phone was working, at 9:45 it wasn't working... I had a green led blinking but no response from any key or combination. When I unplugged it the green blinking stopped but the phone doesn't respond. It doesn't automatically connect to wifi (I've restarted the router to see if it connects)
I'm proceeding to get a refund because mine is 5 days old (16/08/2017)

I know they are slow, but figure maybe the laptop can get it to at least power on. I have tried a different socked to plug the charger in, not going to go and buy a new home charger and cable though if the phone is unresponsive.

If I can get this to power on I am getting all my pictures, contacts and then dumping it. At the moment nothing gets it to power on, just a blinking red LED. It is barely 2 months old.
Edit: Looks like it will be a warranty replacement, the red light is blinking regardless of any type of charger I hook it up to. Any combination of trying to get it to reboot either normally or into recovery fails. My laptop recognizes something is plugged in, but that is as far as it goes. Hopefully I can get contacts off it at the very least, I also hate to turn in a phone without resetting it.
