Segundo os diversos relatos que andam pela internet, algumas pessoas tem vindo a ter problemas do aquecimento excessivo e também em muitos dos casos as portas USB queimadas quando usam cabos USB da HTC, particularmente os cabos USB para MicroUSB.
Aparentemente a parte do conector está demasiado próxima da parte metálica do encaixe sobre si ou seja isto quer dizer que algum movimento mais brusco ou caso o cabo fique sob pressão a parte metalica entra em contacto com os fios causando um aquecimento excessivo do cabo que pode mesmo queimar “fritar” a porta USB.
Esta situação deve-se à escolha de um "conector híbrido" mais económico em relação ao micro usb tradicional.
- Spoiler:
- The case today is an HTC Evo MicroUSB Cable.
This is the same cable that came with your HTC Evo and it may be the one that you still use.
STOP USING THIS CABLE ASAP - IT WAS POORLY ENGINEERED AND MIGHT BREAK YOUR PSU OR COMPUTER!!!!![[PC] Cabo USB da HTC IMG_20110420_163045](https://2img.net/h/1.bp.blogspot.com/-fwf0hUT8MfQ/Ta9aDgahK2I/AAAAAAAAAFs/YMtCTAyTDIY/s320/IMG_20110420_163045.jpg)
I can say this because this is NOT the first time I have seen this same thing happen. You see, this is my Boyfriend's HTC Evo MicroUSB cable and not mine. Mine had the same issue, except I caught it right when it happened as it burned my hand when I was getting ready to plug in my phone at work 3 weeks ago!![[PC] Cabo USB da HTC Microusb](https://2img.net/h/3.bp.blogspot.com/-BMpesXc4Ne0/Ta9aGyXWxlI/AAAAAAAAAF8/f__ShsUDM4g/s1600/microusb.JPG)
This Cable was not engineered properly because of the MicroUSB Connector Chosen. Instead of using a proper MicroUSB Cable Mount style Connector as seen in the picture below, they went with a panel mount/board mount hybrid connector (cheapest as it uses board mount parts) as seen above.![[PC] Cabo USB da HTC IMG_20110420_164023](https://2img.net/h/2.bp.blogspot.com/-sCipelPFdAY/Ta9aCXt4xUI/AAAAAAAAAFk/1M0whgJ4dAw/s320/IMG_20110420_164023.jpg)

What happens is that since the connector shield/metal outside part is not secured beyond two small points, any movement of this shield can cause a temporary dislodging and have the GROUNDED shield touch the 5V power line on the USB cable. Most Modern laptops and desktop computers put out between 500-1000ma of current at 4.5-5.5V which means that you could be having as much as 5.5Watts burning through those cable lines and melting the crap out of some rubber as in this case. This would not have happened is HTC had decided to go with the larger isolated and secured connector or if they simply had chosen to use a Hard ABS plastic instead of flexible rubber to secure a metal part.![[PC] Cabo USB da HTC IMG_20110420_163152](https://2img.net/h/3.bp.blogspot.com/-EHq_3wHpiF4/Ta9aFC0f1qI/AAAAAAAAAF0/htCvcTC2Snc/s320/IMG_20110420_163152.jpg)
What this can Harm:
- Burn out the Power Diode for your USB on your Laptop/Desktop making that port useless (did not burn out my BF's Thinkpad as it is fuse controlled)
- Burn your fingers/hands as it did to me causing a blister.
- Burn out your USB Receiving Chip on your laptop/desktop
- Burn stuff ( a lot of us have a bunch of papers right next to your computer).
Why this matters:
No way in H3LL is HTC going to pay to fix your laptop or build you a house or pay medical bills. They will likely redirect you to the company that designed and manufactured the cable which is likely very hard to sue in the US.
Spend some money on a nice BlackBerry or Motorola or basically any proper cable. $5 for peace of mind is worth it.
