(sigh...) Inside MINE is a "vertical" (since mine is obviously Up-Down instead of Left-Right - YOU GAVE NO PHOTO IMAGE) Black Strip with FOUR contacts and on the OPPOSITE side there are TWO "contacts" that MAY be (and obviously ARE) for the Shield/CaseGround. See this Pinout (both Male and Female) and this Mobo Pinout? I have NO CLUE what you're talking about...

P-I-C-T-U-R-E!!!

I don't have a camera. All I want to know is if a piece of that black coating is worn or chipped, could it damage a device?

I know of NO "black coating" that you refer to. It's Plastic and adheres to the PINOUT link I gave. Did you LOOK at it? Does yours look like it? Are the Contacts (per the Pinout) STRAIGHT? Is the "Problem Area" you speak of going to "touch" the contacts in a cable plugged into it? Can you SPECIFY whether it's on the OPPOSITE SIDE of the 4-contact side?

I don't know... WILL IT interfere or damage? YOU answer some straight-forward questions or you're on your own! You have a nasty habit of avoiding specifics and that cause US (all of us) to NOT want to assist! BE CLEAR! How about (maybe) you use PAINT or some-such and MAKE a picture?

Four Contacts as seen on LEFT on the "Receptacle", Four Contacts as seen on the RIGHT on a Cable (see link given). Is the "piece of the black coating is worn and appears a clear or silver color" anywhere NEAR those Contacts? Is it REALLY a "worn" spot or is it part of PACKAGING that needs cleaned out? DISCONNECT from inside and check it!

Please SPECIFY with some DETAILS DETAILS DETAILS! (IOW, A-N-S-W-E-R!)

"Something doesn't look right... is there a problem with it?"... GET REAL!

DUDE!!!! FOUR PAGES AND ONLY REAL PROBLEM IS HEADER FOR AUDIO!

Rule #12 applies to individual POSTS as well!

(sheesh!!! shouting now... wonder why?)

Sub, here's that image you requested. I hope it makes the problem clear. It's definitely a defect, as I attempted to remove it with a damp cloth and then a screwdriver blade. It appears to be metal underneath the black plastic strip.

As far as I know, and from looking at all the female USB connectors that I have access to, that piece of black plastic is solid black plastic with no metal underneath it. I suppose there is a remote chance that your case is unique, but that doesn't seem to make sense, since all the pins rest against it. Being a conductor, such as metal, could lead to problems, I would think. There is also a remote chance that if you believe the defect is metal that it could be solder that got stuck on top of the plastic, but if it is that it should be able to be pried off. If it really is metal underneath a plastic coating and the plastic is chipped, exposing the metal, then I suppose there is a chance of that creating a problem depending on (1) how far around the chip is, (2) what that metal is connected to, (power, ground, or what?), (3) whether it is possible to create a connection across multiple pins on the USB cable as you are plugging it in or even touch any of the pins for that matter, etc, etc. It's hard to say, but I have a hard time believing that black plastic is not solid black plastic. If I'm wrong, it won't be the first time. :)

Cheers and Regards

I wish it were solder, but it's definitely metal, or something metallic colored. I attempted to remove it with a sharp screwdriver blade and gentle chiseling, but it won't budge. I did insert a USB flash drive into the port, and the drive read and wrote with no issues, but I'm not sure about the future.

If you have a volt/ohm meter, which usually has sharp probes, you could see if the metallic area is connected (shorted) to any of the pins. Test this while system is powered down and unplugged to be safe. You could also try to see with a sharp knife if you could make a mark in the metallic colored area, maybe even see if there is plastic underneath. For that matter, you could see if you could scratch through the non-chipped black area of the plastic to confirm there really is metal underneath the plastic. I still believe it's solid plastic. Or just leave it alone and hope for the best, since it is not causing any problems now. I wouldn't suggest trying to cover up the metallic area with anything since I would think it is likely that whatever you use might eventually flake off while plugging in a cable and gum up the connector deep enough that it would be difficult to clean out.

Cheers and Regards

First, my apologies on the Pinout "on left/on right" - the LEFT one is the "cable" and the RIGHT one is the "jack" (on the PC). Your picture exactly matches.

If you use a magnifying glass to look inside a cable connector (like I just did) you'll note that it's all plastic EXCEPT the four contacts. You picture indicates that there apparently IS a "defect" but it's in the FACE and will butt right up against the rear of the cable connector (which BETTER be plastic). I see no real problem here and doubt you could even cause a failure when plugging into it even if you tried as a cable slips INTO the jack and not ONTO it. SO... if it indeed HAS +5v at the "defect" you'll never be able to "short" anything anyway.

Does this satisfy your concerns?

Does anybody have a USB 2.0 type-A port that they wouldn't mind taking a screwdriver to and chiseling away the face of the plastic strip to see if there's metal under it, too? I highly doubt I have some special expensive USB port. I mean, it's China. So if you think this piece is made out of plastic, which I think so too, then I agree. But something silver is on the face of the plastic strip, and it's slightly indented and appears as a chip, not solder.

Sub, as I said, my USB port pin 1 (the right most pin looking at the port from in front of the PC) is GND, not +5V. In the pinout I used to create my diagram, that USB port was installed so that the 4 contacts were on the top of the plastic strip and pin 1 was called +5V. However, my USB port has the 4 contacts on the bottom of the plastic strip, making pin 1 the GND, right? So if the defect is above the GND pin, as I think it is, is this port still completely safe to use?

DUDE, you are a JACKWAGON!!!

THIS Image is from the LINK pinouts.ru - WHERE is it different from YOURS?

Pin Name Cable color Description

1 VCC Red +5 VDC

2 D- White Data -

3 D+ Green Data +

4 GND Black Ground <--- FOUR! GND LIKE YOURS!!!

LOOK AT YOUR FREAKIN' THUMBNAIL! COMPARE TO THE BELOW IMAGE! FOUR PINS ON THE BOTTOM! It is EXACTLY correct!!! DAY-UM!!!

AS I SAID, It is IRRELEVANT as it's in the FACING!!! YOU tell ME how you can "short" a CABLE when you INSERT IT - NO FREAKIN' WAY! Why don't you do a CONTINUITY CHECK for GND if you wish OR with a Multimeter PROPERLY SET for +VDC (red="bare spot" black=metal casing) while ON to PROVE whether its "plastic" or not!!! It COULD be a "hole" in the FACING where the CONTACT is MOLDED INTO THE PLASTIC! AND IS IRRELEVANT!!!

TEAR UP YOUR OLD CASE'S PORTS (it's empty, RIGHT?)!!! I refuse to tear up MINE!!!

My last nerve!!! You just LOVE to argue, don't you??? Done!!!

You'll not get ONE SINGLE RESPONSE from me... ANYWHERE!!!

If I get chewed for being RUDE, then SO BE IT!!!

EDIT!!! Starting to believe you're maybe one of the SPAMMERS!

Relax, buddy. First, I didn't use that image. I used another image, which is why pins 1 and 4 are switched, because the port orientation is different. What's your problem? You ask for info, and I give it to you. Now you're calling me a spammer. I'm not a USB maker. I don't know enough about the subject, which is why I asked for help. Why can't you be polite and try to help, instead of always being condescending and rude? Take a page from bphlpt's book. It's not a hole in the plastic for a contact. I'm selling my old case, so I don't want to ruin the USB port. I wasn't saying take a used working port on your live system and destroy it. I asked anybody if they had a defective USB 2.0 type-A port, if they would take the job. Where have I argued with you? I actually agreed with you about that strip probably being 100% plastic.

You never said that you said this

Now, look AGAIN at YOUR Picture - DID YOU SAY THE PIN# REVERSED? No! And THAT, sir is... IMPOSSIBLE (that they are reversed)! MAYBE you are CONFUSING the MOBO PimOut Pin#1-4 (which has NO BEARING on the Front Connector) - see attached (YOUR MOBO). See how the OTHER ONE is Pin#2??? 1-3-5-7-KEY and 2-4-6-8-NC - "A NOT= B" !!! Good Glory! SURELY you're not as dumb as a bag of rocks and this is some kind of joke!

edit - Try disconnecting the Front Cable and do a Continuity Test between contact and the cable connector - bet you're WRONG! HUMOR ME!!! DO IT!

----------- Did you even THINK of something like this?

and it's slightly indented and appears as a chip, not solder.
Electronics Forum...
Yes, virtually all epoxies & most other glues are completely non conductive when dry, unless specifically stated otherwise.

In fact, epoxy is often the material of choice for high voltage insulating jobs. It's also what most circuit boards are made of.

Get some, mix it, smear flat with a piece of paper and let dry. DONE! Problem solved!

The horse is dead! Long live the new horse! Move on to something useful and quit bugging people...

Actually, Sub, I did tell you. I even wrote a note below the diagram explaining it. I've attached the image I used so you can see why I said that.

Now, notice how that USB port has the four contacts ABOVE the plastic strip and pin 1 is +5V. Well, my USB port has the four contacts BELOW the plastic strip, so I assume pin 1 is GND, because if you rotate the USB port 180 degrees, GND becomes pin 1. Do you understand me?

I just tore up a USB port. There is no metal inside the plastic. Other than if you break it enough you will see the pins from the other side.

Regarding the ports arrangement, there is no "up or down" standard when manufacturers put together their cases. For the most part, they may have a quality control measure to make sure all ports are facing the same direction for the entire production line, but it does widely vary as far as which way they are facing when they have a vertical orientation in a case.

BWAHAHAHAH!!! That's STILL correct even if UPSIDE-DOWN!

1-2-3-4 (pinouts.ru)

4-3-2-1 (yours upside-down)

Mine are "sideways" - does that make them all "1-1-1-1" or would that be "4-4-4-4"?

If a Commercial Jet flips over, does the Pilot/Copilot Seats magically "reverse" (or "mirror")?

Ennyhoo, you've been specifically answered. I'm betting it's a "coloration bubble" from when the plastic part of the component was molded over the contacts. Same thing can happen when Fiberglass is mixed and spread (check out some aftermarket fiberglass automobile products). ;)

Indeed (from another of your topics - CPU Upgrade)

This is my main system. This system meets all my current and, as far as I can see, future needs. I have absolutely no desire or need to upgrade my system now or, as far as I can see, ever. I know exactly what I'm doing and have put extreme thought into future-proofing my system.

Move on, please... :whistle:

Thanks so much for doing that. What do you suppose this anonymous metallic defect could be? I highly doubt it's solder, as that's white, not metallic. It appears to be a slight indent from a scratch where a round portion of metal shows.
