Hi all - does anyone know if it's possible to connect the N1 to a PC (to do adb, shell etc) without charging the battery? Reason for question is, I am trying to do some kernel/configuration benchmarking and do not wish to skew the battery usage/uptime figures too much! (fairly theorhetical question, I guess, as I realise accessing the N1 via USB could itself use battery)
I don't believe there is a way to do that. the only way I could think of is to get a usb that can only transfer data and not a charge for the battery.

Cut up your USB cable and clip the wire attached to pin 1.
Caveat: I haven't tried this but it's certainly possible.
There is such a thing as un-powered usb ports. However, I believe the name is misleading, as in reality they are simply low powered (if memory serves correctly). However, it might be worth looking into if you can't successfully clip the power as in the previous post.

An unpowered USB hub will still pass power. It just gets a maximum of 5v from the computer so you can't power multiple devices that actually need any substantial amount of power.
A powered USB hub just makes sure that all of the ports get their full 5v.

Ok, so hoepfully someone can clear this up as I don't yet have my Kaiser (tilt) and am trying to get some accessories.
I previously had a PPC-6700 which synced and charged via a standard mini-USB jack.
I then upgraded to the PPC-6800 which I only had for about a week (had to give it back to my work). With that device there was a different type of usb jack on it that seems to be what the Kaiser also has. Can someone tell me what this is called?
From my recollection however, this slightly different jack would also accept the typical mini-usb plug as i can remember using my PPC-6700 wall charger on it.
So can you use standard USB to mini-USB plugs to interface the Kaiser with either a PC for sync/charge or to a wall-charger? What is the new interface called and what is the point of it?
thanks much!
I may have actually answerd my own question as I have found (I think) the name for this new interface... EXTUSBTM ? Is this correct. And the point is to interface the charger/sync and audio headset together?
If this is all it does then I should be fine using all my old mini-usb plugs for data interface/charging, right?
thx!
Yes, you can use a standard 5 pin mini USB cable. The port is HTC's 11 pin combination sync/charge/audio port. Both their plug and the standard 5 pin mini USB plugs fit and work.
Wikipedia (for once!) isn't too big on details here: http://en.wikipedia.org/wiki/HTC_ExtUSB
But basically, it's got 11 pins to handle audio, power and syncing.
Have a look here for pinouts etc.

AT$T Cheaped me out again. I only got a standard USB sync cable from them! DoH! lol
Hi
I don't know if people realise this but you can modify a generic car charger to automaticlly activate the Navi Panel mode so you don't need to buy the SU400 kit.
You will need a car charger that is capable of suppying 1 amp, to enable fast charging. ( Use an app called Spoon Charge to check) or disassemble the USB Micro A plug and ensure Data- and Data + are soldered together. DO NOT solder Data - and Data + togehter if not already done so this means the device is not capable of supplying 1amp.
If so you should have a unused pin ( this is called the ID pin) solder this along with Data + and Data - to OV.
When the charger is connected it will launch Navi Panle if enabled and turn on bluetooth and pair to a set device.
I will take a pic of the modded plug and post it up. In theory I would assume the same mechanism is used on more than this device.

OMG LEGEND bro. lol. Finally someone figured out HOW to do this so you don't have to buy that overpriced HD2 carkit. Thanks. Mod's this should be a sticky.
mods seriously this should be front page news
Are you sure, that this will work? Did you tried it yourself? Cause my CU-S400 is also activaiting the Navipanel even if i don't have plugged in the Charger! So I think that it hasn't anything to do with the mAh-size of the charging unit....
You're right.
Right connections for recognition Car Kit Mode :

Source.
I created a docking station for the hd2 with the following materials:
- cd dual case
- dtech solar usb hub
- mini key usb keyboard
- Kensington Universal Multi-Display Adapter
- multiple usb cables
You can connect two usb devices (usb-host only works in winmo and linux so far). Two usb ports are inside and always connected to keyboard and displaylink device. The dvi(vga)-video out function only works in hd2 linux with displaylink framebuffer installed. The 5V for usb host can be provided from external power source (usb in) or from internal battery. The internal battery (700 mAh) can power hd2 and usb devices for approximately 30 min (depends on usb devices). The internal battery can be charged over usb in. It can also be charged with solar cell but it takes forever (The actual purpose of the solar cell is to compensate self discharge).

hd2 with an external monitor is great...so kensington display adapter it s an external usb video card,so you can have dvi output.At wich resolution?
I think at least less than 1600*900 because when I set that resolution in xorg.conf xserver wont start. I tried several different lower resolutions and I got an image on second screen but image actually always looked the same as if resolution was unchanged. I think this is a bug. But hopkinskong is still working on the matter so we will know for sure when he releases the final version of hd2 slackware.

Whaaaat!?? Yet another battery app! yeesh!
Hey, don't be like that. This time its different. It's not about making your phone charge faster or extend battery life. This time, it's about STOP charging your battery.
Want to stop charging your Android phone's battery when connected to Computer USB?
You are a developer that often connect their phone via USB and don't want the battery to suffer?
Disable USB Charging will disable usb charging (obviously...). Allowing you to connect your phone via USB without straining your battery again and again and again.
---
Roadmap
Automatically disable USB Charging at 80% battery. And automatically enable charging when its < 80% battery.
Better user interface for tablet.
Support for disabling charging on Quick Charge device (dunno it already works or not, i have not tested it).
Force Enable charging on tablet when connected to low-power USB charger.
.... please add...
---
Please mention your device, Android version, and ROM if it's not working for you. Thank you.
Best app 2k16, thanks a lot! Working fine for my Huawei Honor 5X.
Update: Doesn't seem to work on my Moto G 2013 (falcon). Any idea why?
I understand Note can charge devices such as my Bluetooth micro USB earphones, however i am straggling to get right cable i.e. micro USB to micro USB and perhaps an adaptor on Note 8 to convert it to C type.
Anyone done what i am trying to do?
Use the otg adapter that came in the box

Normally you only need to use the included OTG adapter. Connect it with your note 8 and connect a normal USB cable (USB to micro USB) with the device you want to charge. It should be automatically begin to charge the other device. Maybe you need to pull down the statusbar and tap the "android system charging" notification and tap it. Then it should open the menu you will see on my second screenshot. Select the last entry "charge connected device" and there you go. It should be charge the connected device

Don't be afraid to hit the "Thanks" button if someone helped you. It don't hurts
Completely forgot I had OTG adaptor, that will the connectivity type issue
Thanks
