[Q] Is the HTC USB cable special or something? - Desire HD Q&A, Help & Troubleshooting

Since I do not have the original one for this phone I tried my Nexus 7's USB cable and its rather loose, I don't think I can flash a ROM with it due to the chance that it comes off during flash(which it does from slight movement when connected as MTP; its not coming off per se, but it does get disconnected).
But why does it? MicroUSB should be identical, or is the DHD USB port broken?

All microUSb cable are the same.
You can try to clean usb port.
You can find plenty help page on internet with: how to clean microUSB.
It doesn't matter for witch phone. All are the same.

USB Port - Proprietary???

I have a Tilt 2, had it since last March. I've had to have it replaced twice already due to the USB jack getting to the point where it no longer functions except to charge, it won't connect via cable to the pc, nor will it work with the multi-function adapter provided at purchase by HTC.
Is it dangerous/wrong to use after-market chargers/adapters/standard usb cables with the phone??? Am I damaging the usb port by using car chargers/wall chargers, etc that I got from ebay, or is this just a matter of bad design?
It isn't. It looks different, but its not. I believe its ONLY notched like that because not only is that port a USB port, but it also has a few extra 'wires' for connecting a headset to it. (via the HTC adapter)
Of course, the corporate answer is.. Yes using a non HTC Power Adapter could damage your TP2. But unofficially, I doubt it.
I've stopped buying over priced chargers for my phones and will by any Mini-USB charge that I can find. Most will work. The voltage does not matter anymore since USB is a set standard, and any modification to the voltage would not comply to the USB standard, and it wouldn't be USB then.
I've had the same issue with my TP2 (and with the HTC Wing I had before). Check the power adapters itself. I have a RAZR charger I've been using for years, and I think the plug itself has just about had it.
Also take some canned air to the USB port on the phone (while it is powered off and battery removed) and try to remove debris from the USB port. The minuscule little piece of dust could cause a bad connection. Electronic cleaner works better at this. (its LIKE canned air but contains alcohol-based cleaner in the "air". It's available at Radio Shack.) This fixed the problem I was having with my Wing.
And finally, it may just be time for a new phone. The ports just plain wear out from daily plugging and unplugging that adapter in. One slight bend and the port is all out of alignment.. (does it wiggle instead of being a firm connection when you plug in the charger?)
This is why I am waiting for the day these induction charges are standard in phones.. No more power adapters!
I just use a normal USB plug for mine. I don't even fool with the one it came with so I don't get that one confuse with something else. They only notched it like that to make a buck, I would guess.
If you are trying to use Mini USB headphone, only the ones made by HTC will work as it has 11 pins. Standard Mini USB has only 5 pins.

Have you tried other USB cables? I have the same problem with my stock USB cable too and thought there might be something wrong with my phone, but then I tried a different USB cable and it held on well.

This was my experience as well. Try other cables before you swap out your phone! :good:
The same with my cable. I guess they did it on purpose, that whenever your phone is 'tugged' the usb cable will be released instead of your movement being violently restricted by the force of the cable, which may cause you to drop your phone.
Any way, i bought a 3rd party flat USB cable which length exceeds 3 - 4 times the original cable , and it fits tightly in my phone's USB port. So i believe it is cable related.
I have the same problem, I guess it's just the one they sent. Oh well.
I did buy another cable, however I noticed that charging becomes extremely slow with it. I'm hoping to be able to find a better one that can support the higher charge needed for the phone, in the meantime I'll be leaving the phone down while charging I guess.

+1 same thing for me too. I was so worried thought it was a problem with the charging port but it seems the problem is with the charger cable. Using other cable is no issues.
Obviously it pops out very easy. I'm on my 3rd Samsung Micro USB cable, all are same.
But then I've tried my friends Galaxy Ace cable and it was fine. So you just buy a different Micro USB cable which will have same 2A output like stock one.

I. too, was worried when i first got the fone.... but it's the stock cable... tried another cable from another brand/manufacturer and it fits perfect.
I seem to be quite lucky. My stock cable fits nice and snug. I can even dangle the phone upside down holding only the cable and it wont come out unless I swing it or tug it harder lol
If you compare the stock cable with other cables you'll see that the plug on the stock cable is usually shorter than other cables by a millimetre or 2 so the little prongs on the plug probably arent grabbing onto the slots of the phone
Mine 2. I just stick blue tack on it

Yup, same here. I find the cable that came with my wife's Kindle is the best fit - needs a real pull to detach it!

[Q] USB Port not working

I have an E4GT and my USB port is being fickle. It doesn't connect unless I hold the cable in a strange upward tilt position.
In order to rule out any software cause for this, I ODIN'd back to stock but that didn't change anything. I tried all sorts of different USB cables (stock cable, monoprice cable, HTC cable) but no dice.
Anyone have this problem? is the USB port portion soldered on the motherboard or can it be replaced easily?

USB cable issues (keeping connectivity)

Hi all..
this is a general question really about the issue with Micro USB cables and the connector's ability to stay connected.
I know it isn't my phone as when i buy a fresh cable it clicks in nicely.
Does anyone recommend a decent cable where the connector stays connected after more than a few weeks of use?
I've obviously used Stock HTC, but also PortaPow (power only), Blackberry cables, Nokia Cables, Samsung with varying success.
Thanks

RK3188 1024x600 front USB not working? Any workarounds?

I'm not able to get to the bootloader screen because the front usb port is not functioning on my unit. Has anyone been able to use one of the USB ports on the back to get to ADB and/or get to the bootloader? Is this a known issue with a workaround? I've done quite a bit of searching and have not turned up any solutions. Considering what is involved in shipping this back, I'd much rather figure something out. Thanks in advance for any help!
Edit: I should mention that I have used the adbon password and it does acknowledge that adb has been enabled. Just nothing seems to work on the front port. When I connect my Linux machine and run lsusb nothing shows for the unit. I have considered buying or making a USB-A to USB-A cable to connect my computer to one of the back USB ports, but I'm concerned about how these back USB ports are designed. Is it as simple as a built-in OTG cable? If so I'm probably fine. If it is more like a computer's USB port I could damage my laptop, my headunit, or both. I'd really like to hear if anyone else has had to deal with this. Unfortunately I haven't verified if the front USB will charge a phone. This is my next step.

My front USB also doesn't work. I even got mini to standard USB cable with unit, but plugging flash drive into it doesn't produce any reslt.
I also plugged extension cable to one of back USB ports and tried it (plugibg same USB flash) but it doesn't work either.
So I'm also confused.
Does that mean you are still running the stock ROM? I have been hesitant to install the custom ROM because they say you must be able to get into the bootloader even though I couldn't find a step in the process that required it.
Regarding the USB ports not working at all, you may find that you need to use a powered USB hub. I've seen reports of USB devices acting up due to the low power. This is one of the reasons I thought it might be safe to use the rear ports with my computer. (My first real test is going to be mangling a male-to-male USB cable so only the data lines are connected to see if I can get those rear USB ports to talk to the computer. I figure that way there is no chance of frying any circuits.. Each side already has its own power and I don't believe any signaling is sent via the power pins.)
On my unit (MTCB-KGL-V2.80), I have used a T-Mobile USB broadband modem successfully on the rear port, so I know rear ports are live. I did take it apart to see if something was obviously wrong with the front port, but nothing jumped out at me.
So I have a bit more information on my headunit. BTW, I have the BMW E46 model with MCU MTCB-KGL-V2.80.
On my system, both the front USB port and the rear 3G USB port are wired as device ports connected to an AU6258 USB controller (http://www.sunnyqi.com/upLoad/product/month_1403/201403162331285643.pdf). I don't remember exactly which USB ports they are connected to, but I believe the 3G port is connected to port 2 (pins 6 & 7) and the front USB port is connected to either ports 3 or 4 (pins 9 & 10 or 11 & 12 respectively). Nothing is connected to port 1 or to the upstream port. The other rear USB port is wired directly to the MTC_RK3188 board.
All three ports are wired with only four pins, so I'm concerned that none of them could work with the computer. The USB controller doesn't have USB ID pins, so does that mean that the 4 downstream ports are OTG and the upstream port is for a computer? Unfortunately I don't know the hardware side.

No I flashed Malaysk ROM from GPS SD card. No problems. Just follow instruction. I had luck that I didn't need to recover from USB.
Did you tried with USB powered hub? I don't have one to try it myself.

I checked on my Linux workstation with
Code:
lsusb |wc -l
plugging and unplugging all three USB cables and the number did not change. BTW where did you use the "adbon" command? The only place that I could even try was at Settings > Factory Settings. Regards Flint
