What is internal USB jack for?
What is an internal USB jack for?
Running XP SP3, using an ASUS mobo that had only usb1.1, so I bought a USB2 card a few months ago and everything is fine. It has another USB jack on the card, not the mounting bracket, and since it's hard to reach the back of the computer and the side cover was open, I inserted a flash drive into the port. Everything stopped, the cursor wouldn't move, the keys didn't work, the icon for a USB device didn't show up. It's possible my belly hit the keyboard :-( , but I would expect things to soon get back to normal if that were the problem. Had to use Reset button to warm start the computer. Now I'm afraid to plug anything into that internal port?/jack. Documentation with the card didn't even mention it existed. I wasn't sure it was even a jack until I read something that made a vague reference to an internal jack. What is it for? P.S. Flashdrive has worked fine in the past and has worked fine since, plugged into a jack on the mounting bracket. Thanks a lot. |

I wasn't sure it was even a jack until I read something that made a vague reference to an internal jack. What is it for? Typically internal USB jacks are no different than external ones. I've added internal USB ports to my own system for years, typically to add Bluetooth adapters or similar to a desktop. For many moons I used a card reader that had a standard USB cable connector on it rather than connecting directly to motherboard USB headers. The instructions suggested that you snake the cable through the case, out the back and connect it to an external USB port. I had this card reader connected to an internal USB port that I added as well. It's possible that your USB card used a similar formfactor for something else, but honestly, I can't imagine why they'd bother with a USB header, it would make more sense to skip the connector and go with bare pins if the port had some other purpose. It is also possible that the internal USB port wasn't a dedicated port but rather that it electrically shared pins with an external port (in other words, the card's chipset might support 4 ports, the card might have 4 on the back and 1 inside, allowing you to use 4-external or 3-external + 1-internal) -- I've got a SATA card that "shares" one of the internal SATA ports with the ESATA slot on the back in this fashion. If you connected two devices to one pair of hybrid ports the results would be unpredictable. |

"mm" wrote in message ... was open, I inserted a flash drive into the port. Everything stopped, the cursor wouldn't move, the keys didn't work, the icon for a USB device didn't show up. Some so-called "4+1" USB cards, where the "+1" is actually on the card itself and the "4" on the backplate are incorrectly described. The internal one is not the fifth USB port but is actually wired in parallel with one of the "4" that appear on the backplate. You can see that by plugging something into the internal one you may well then have two USB devices plugged into the same port - and that may well be what locked your machine up. The internal socket cab be useful where you have a bulky USB device to plug in. I use a "4+1" card with an ASUS A7N266-VM and I plug my wireless network dongle into the internal "+1", which leaves me with 3 backplate USB 2.0. It works OK - even though it is inside the PC! By the way - for God's sake, post intelligently and so help us to help you. Don't just say "ASUS mobo". Identify the mobo - and the USB card. If you are using the same motherboard as mine, you might like to disable the on-board USB 1.1 in the BIOS as there is a known compatability issue which causes random errors on plug-in USB 2 boards. |

Now that's interesting! I have a cheap'n'nasty USB card from one of those electronics clearing houses in HK that's given me trouble on both of the computers that I've tried it in. (Both Tualatin PIII boards, so worth keeping, without USB2.) Thanks for the tip. I don't think I threw the card out, if I find it and try it again I'll try disabling on-board USB 1.1 in BIOS.
