Anyone having issues using aftermarket wall chargers with the EVo?

[zanda61]

I've been using several different 1000 ma chargers with various micro usb cables and all seem to charge the phone just fine.

One thing I've noticed though is that I can only use the HTC Sync application with the HTC cable. I was wondering if anyone else has had any luck using HTC Sync with a non HTC cable. Thanks for any insight guys.

In fact, I just rooted my bitch and ran dmesg under several scenarios:

unplugged
plugged into USB on computer
plugged into HTC stock USB to AC charger
plugged into Plantronics AC charger
Plugged into HTC stock USB to AC charger from TouchPro

The Android clearly runs a process to identify the manufacturer of the charger:

"Get USB ID PIN, mfg_df_serialno: 0000000000, usb_switch_dummy_serial_num_by_GPIO,usb_id_pin_gpi o 37

usb: mfg_USB_ID_pin_status: 1, ID_Pin 1:1,usb_switch_dummy_serial_num_by_GPIO
usb: suspend
usb: not AC charger."


But when the stock charger is plugged in:

"usb: AC charger"

It even instructs it to slow charge under certain circumstances.


Please. Someone hack the crap out of this.

I got it!
so i too was having the same problem, i was like "wft?! thats such an apple move HTC, and apple doesnt even do that..." so i i was just messing around (while playing CODMW2), and turned my phone off just to soft reset it. and thought "lets see if it really does charge while the phone is off". (and it worked) so after about 15 mins of charging while the phone was off, i turned my phone back on bc i didnt want to miss any calls. i kept the plug in, and to my surprise, after the phone turned on, it continued to charge! so i thought, to keep it charging with the after market charger, just turn it off and then back on again and there you go! but i unplugged it, and plugged it back in and it still charged! and so far it works with that charger without having to power down and power back up! and it still works with the OEM charger! problem solved!....? someone else try it and see if it work...
also, this seems kinda long winded, but im kinda drunk right now... YAY!

Shell

I just took a look at the amperage on my plantronics charger and it does like 180ma...i'm guessing the phone tries to draw WAY more than the charger can output and the internal circuit protection in the charger kicks in, otherwise it'll just burn out.

Taken from a post I did at XDA inquiring about USB fast charging...

"the ma rating of the charger really makes no difference as the phone (and prior htc phones) will pull <500ma if they detect they are plugged into a computer or non-official charger and 1a if they detect an htc charger (which can even damage 500ma chargers). The way this is detected is through grounding of one of the microusb pins in the official charger (and indeed many generic chargers but not all will be detected this way). Absent this grounding (I forget which pin), it will charge at a slower speed. I know of cheap 500ma chargers which have been caused to smoke by attaching a cable with that grounding fooling the phone into thinking it is an oem charger. Many chargers labeled 1a will charge at the 500ma rate as well."

I had a feeling they were doing something like this. I wonder if it's the same way Apple does it. Has anyone tried a USB charger made for Apple devices to see if the EVO detects it as AC?
Also, is there any place to buy an official HTC wall charger?

Thanks. But, I was actually looking for the same one that comes with the phone. (It's the same one that comes with the HTC Incredible BTW).
