Kaiser/Universal mini usb

Before i got HTC Tytn2 i had qtek9000. I had also Brodit car holder and instalation in car with cool hidden cable for charging qtek. After i bought Kaiser i also bought Brodit holder for Kaiser. I thought that this miniUSB should charge battery but it is very strange. Kaiser shows "charging" but battery is not charging. On normal 220v original Kaiser charger it works like charm. Are pin combinationfor these two smartphones different?

As far as I know the pinouts are the same.
There is a blog here which describes the HTC ExtUSB socket and also mentions that there are 2 charging modes. The faster charging, higher curent, needs 2 pins to be jumpered. Without this fast charge the current is limited and may not be sufficient to actually charge the device if you are actively using it. eg. GPS, 3g, Music etc. Try using the charger with the Kaiser in GPRS only mode, or Radio off, and with no apps running, this will enable you to see if in fact it is charging but at the slower rate. The Kaiser may need more power than your Qtek needed.

do you maybe know which two pins?

Quoting from the blog...
As for the power pins question this is simple a case of juice.
If I plug the USB cable into a HTC device, then plug that usb cable into a usb port and just wire that up to a bench power supply... the device draws a few hundred milliamps. (As much as USB spec allows).
This device, much like other mobile devices I have used which USB charge, can barely draw enough power of the USB to run itself let alone charge the battery.
However, if you close the A/B pins you are telling the phone "This is not a USB port, its a 1A power brick" so the phone charges the battery at its maximum safe rate.
This behaviour is stop the phone frying your usb ports.

Hope this helps

I had problems with some cables and some car chargers. It turns out that when I use a cable for sync that is fully USB 2.0 compatible everything works. For charging in my car I bought a universal car 12v to USB converter. Then I am usinging the same USB 2.0 sync cable with it. It works.

When i first got my kaiser, i used the car-charger from my old MiO A701. For a period of 1,5 month, it worked just fine. After that, for some reason, kaiser shows that is charging but it really does not!
I thought it would be a charger malfunction, but after reading the posts above i have my doubts...

Problem charging

One of my Tilts suddenly won't charge on some chargers:
HTC AC charger - OK
USB to PC - charge and sync OK
HTC compatible car charger - no charge
Blackberry AC charger - no charge
My second Tilt is OK on all four chargers (as expected).
I am suspecting a problem with the usb connector but looking for a reason why some chargers work and others don't.
Any insights would be appreciated.
Thanks

I saw a few weeks back a thread on this very forum that examines this problem in detail -- keep searching

Problem Charging
I think I 've read everything relevant. I am looking for someone who has h/w insight into the Kaiser charging scenarios. I suspect mini-usb damage.
I am somewhat familiar with HTC's pin 4-5 implementation to detect a true charger as opposed to a usb connection that can also apply power.
I want to eliminate software possibilities.
How can a Kaiser charge from an HTC AC charger and also charge from a USB connection to a PC....but not recognize a car charger or a third party AC charger that does not implememt the pin 4-5 grounding technique to identify a charger (and not a generic USB connection).
That is where I am lost.
Looking for "inside-out" knowledge...not "outside-in", if you catch my drift.

charging problems
If the car charger worked before, you can do an easy test. Just put in the car charger and do a soft reset. If it starts charging than, its only a software issue. I did a modification on a charger myself. Because I have different chargers using a normal USB cable, my device didn't charge alway as well. I modified a standard miniUSB cable by connecting the 5th pin to ground. When I use this cable for charging I never have a problem anymore. Succes.

I had exactly the same problem after I tried to re-set my device by poking the stylus in the mini-usb port instead of the re-set hole (tryng to do three things at once!). The port was mangled, and once i'd pushed it all back it wouldn't take a charge from the genric car charger. I bought an HTC branded car charger and it charges as good as a wall adapter.
I imagine that your suspicion of USB port damage is correct.

[Q] Whats With Charging This Thing?

When I first got the phone earlier this week, I could plug it into the charger in the wall just fine with no issues, it would just charge. Now suddenly it started telling me USB connected and goes to the MTP screen and of course locks up the phone.
I can of course bypass this by switching the phone to mass storage mode, but since I have Kies and use it occasionally, it would be nice to not have to switch that setting each time depending on my charging/syncing situation.
Why would it have not locked it up with the MTP screen originally when charging from the wall but now it does? The results are the same whether its plugged into the wall or the USB port on the computer. I have two Captivates bought brand new on a family plan, both do this now with any combination of chargers and USB cables, wall USB port, or car charger. Neither one has a common application installed since the other is my girlfriends who hasnt done much to it yet, so Im blaming the phone itself for now...

Interesting. I just checked with my BB charger and they dont do it using that charger, but they do it as soon as I connect the stock charger again.
Im wondering if its a voltage sensing circuit thats tripping due to the different voltages which should be applied - either wall charger or USB port. Maybe for some reason my wall chargers arent putting out enough voltage and its thinking its a USB port, but the BB charger is putting the right amount of voltage out?
Am I on base as to how it differentiates between wall or USB port? The number of pins obviously doesnt matter as all the cables have all the pins in them, unlike some charger cables which only have the power and ground. The only thing I can think of is that it uses the amount of voltage/current to tell the difference and create its reaction.
~T.J.

Sounds like a problem with the stock charger, maybe usb cable alignment. My iphone wall adapter does this with the samsung cable but the samsung wall adapter doesn't, same with my car charger from att. Also I have a $5 walmart car charger that has a cable that splits into both a mini usb and a micro usb that isn't a real usb cable, it's charge only. That cable has no problem on any wall or car adapter. I believe the phone detects if its connected by checking voltage on a data pin (just a guess really) so if a nonstock charger is used it assumes that it is a computer. But it may also be a data signal that is given off by the charger.

did you try a new charger and if so, did it work? I've had my captivate since Thursday and on Thursday it charged and everything fine, but then yesterday,
a) no computer I connect it to while recognize it, no matter what I have it set too and have latest drivers installed
b) if I charge it, after I unplug it, it locks up to black screen and I have to remove the battery to get it to work
c) I also have an in-dash touchscreen monitor in my car that has a usb port because it works with an ipod. I plugged the usb into to use it as a car charger, unplugged it, same thing
d) it did say usb connected after it was unplugged, but I switched from mass storage to ask on connection and it went away
so is an actual wall charger the solution?

and now I unplug it, and if it locks, it will not unlock, just black screen
I have to take out the battery and then only way to get it to turn back on, is to plug it back in the wall

^^^Ouch that's not right, if you can't figure it out you may need to re-flash or just bring it back under warranty, or insurance

[Q] Modify car cradle to automatically enable car mode ?

Hi there,
I just bought an active car cradle for the Htc HD2 (Carcomm), no problem, working as expected.
Then I began wondering why the phone would not go into car mode when connected to the car cradle... If it's a car cradle, it should put the phone into car mode, right ??
So I was wondering what could possibly trigger the phone into car mode when connected to a charger.
Found this in another thread (http://forum.xda-developers.com/showthread.php?t=767961):
To the person who wanted to know about connecting pins 2&3 to 4 to create a car doc? Looking at the USB spec datasheet It's not that simple. You need to insert a voltage divider across the data lines and tie it back into the 3.2v of the device. A little more trouble than it's worth unless you are doing it for the learning experience.

and also from user dabigcheezze :
unfortunately it is a problem with froyo, whenever the phone is placed into dock mode, no matter what the charging input, it will only show up charging in usb mode, i have a homemade dock cable with pin 4 to ground, when i hook that up to my 1 amp charger it only shows usb, using a normal cable it shows ac charging, it has nothing to do with the HTC dock, it will happen whenever the phone is placed into dock mode, it also locks the vol output on the 3.5 jack 3/4 up....sooooo stupid.

Does anyone know about grounding pin 4 to enable car mode ? what about power, is the charger powering enough the phone while using BT, GPS and navigation ? Also, the limitations in Froyo are they gone in Gingerbread or could it be fixed ?
Thank you for sharing your experience, I would really like to have a car cradle working 100%

Nobody ?

Come on, I'm sure somebody did the modification... or tried to do it
Willing to share ?

Hi !
Just wait I can contact the guy I wish to buy that second hand HD2 first, then find an appropriate car charger craddle, and I'll look for a solution.

Don't know how to automatically enable car mode, but just solder the 2 middle wires in your USB cable together and you'll get 1A instead of 500mA, which charges way faster. Your car charger needs an output of 1A, of course, else it's just gonna remain 500mA.

Thanks for your reply. Yes, it's true. I've seen this small hack to enable AC charging for cheap chargers that are charging with USB mode (400mA I think).
My charger was good enough to provide AC charging (1A), which is great, but not enough to enable the car mode...
What I would like to confirm is if grounding pin 4 will really put the phone in car mode when plugged into the car cradle, before doing it myself...

Do not hack the hardware!
Use a software
http://forum.xda-developers.com/showthread.php?p=8178010

Thank you for your response.
But... is it a software for windows only ?
I run Android on my HD2

Unfortunately, the software only runs on Windows Mobile :-(
So you have to try that:

I personally ordered the original car holder from htc and it is really a very good one!

Excellent !!
I think that if the mentionned modification works with a HD2 AND a Desire HD, the official Htc android software should work also, like the windows software in the video.
Thank you, it's great ! I will post here my results when done

Even easier - try using PhoneWeaver (can't add a link as a noob)
It's basically an app for setting your phone's parameters, based on all sorts of external influences, such as time, date, power source etc.
So, for example, I have the following settings:-
6:15 am - turn phone on, set volume to Normal
8:15am - set volume to low (for when I'm in the office - its a personal mobile)
4:45pm - set volume to Normal
6:45pm, turn wireless on (as I'm at home, and browsing is much faster)
10:00pm - turn phone / wireless off, set volume to low, start SPB Time (my alarm clock)
Additionally, I have the following:-
If external power is detected AND Activesync isn't running (ie it's not connected to a PC) then turn on Bluetooth and increase volume (this is because the only other possibility for this environment is when its in the powered car cradle)
If external power is detected AND Activesync IS running, turn Bluetooth off, but turn wireless on
It's completely brilliant - never fails and I never have to remember to do anything

[Q] Z3c won't charge on DK48 dock

So, I have the official Sony DK48 dock for my Z3 Compact (no case). The phone will recognize that it is connected to the dock by giving the notification sound, but the battery will not charge while on it. I've tried wiggling it all sorts of different ways, and tried at least 3 different USB cables, but still no dice.
Is anyone else having this issue?

Have you used original cable? I had this problem with some poor quality cables, they were too thin inside for the designed current

plug it in the mains...

With 'mains' you can mean so many things.
I guess you mean plug the cable in an electrical outlet, rather then in a computer. I believe that I had the same issue. (Worked fine in an outlet)

The DK48 will only charge the phone when power comes from the mains. It does not charge the phone when connected to a USB port of a PC or laptop.
Use the original charger and the original cable that came with your phone and the Z3/Z3C should charge just fine in the DK48; that's at least what my does.

Yes all of my attempts occurred while plugging the dock into the AC adapter that came with the phone.

I guess then it seems like its a faulty DK48...
It should work with the original cable, adapter and electric outlet (not a PC).

Why wouldn't the DK48 charge through PC? How does it know? Amperes?

The input from the computer is too low even when you plug the USB to 3.0 port... Unfortunately you MUST use wall charger for the DK48 to be working.

I am a bit late in this thread, but I will post it anyway in case somebody has the same problem. Dk48 won't charge phone while connected to PC, because it checks if data lanes in Micro USB port are used. If they are, charging is stopped. If someone wants to charge phone using dock connected to PC (I for example connect it to my active USB hub, which is connected to my PC) it is necessary to use Micro USB cable, which doesn't use data lanes, just charging ones.
I hope it will help somebody.
