3 USB ports missing +5 Volts., HP X18 1027CL Laptop, Win7, USB powered cooling fans, no message.

Has anyone else seen this before. I have been using this process to supply coooling to the laptop for a long time, but today the cooling fans quit and now none of my USB ports will recognize any of my devices that require +5 Volts.

You should have used the cooling fans with an externally powered hub. You may have fried some of the traces going to the Southbridge chip on the system board of your notebook. This limit for a USB port is in most cases 500 mA. You may have exceeded it.

When I connected my iPod Classic or iPhone 4S to the right side USB port of my 2012 11 inches Macbook Air (128 GB SSD), I get a message from iTunes that I connected my device to a USB 1.1 port. I checked the specs, it's a USB 3 port. What's wrong?

I have three ipods, none of which is being recognized by my itunes. I have the current editions and tried different USB ports. The mouse works just fine in the USB port. I have reset the ipods. Any ideas if it's the USB or the ipod or what's going on?

I have three ipods, none of which are being recognized by my itunes. I have reset each ipod, with no results. I wonder if the problem isn't with the USB ports. The mouse works fine in each port; nothing happens when I plug in the ipods. I have tried two different USB cables. I have no other USB devices with which to test. I have made sure I have the most recent updates and rebooted the computer. Any idea what is going on?

Problem with USB port on X6 docking station and X60 laptop

Hello all,
One of my users is having a problem that when she undocks the X60 laptop from the X6 docking station and then re-docks it later, the devices connected to the USB ports on the X6 docking station are no longer recognized. Even after repeated re-boots I can't get the USB ports to work. The USB ports on the laptop still work, but not on the docking station. Anyone know what I need to do to fix this?

BIOS 2.19 is for X61 series not X60(s).
Here're my solutions.
Solution 1. Unplug all USB devices from docking station. Reset BIOS to defaults, save settings, reboot, plug all devices back. All of them should work now.
Solution 2. Power off your system. Un-dock your laptop. Unplug all USB devices from docking. Re-dock your laptop back again. Power on your system. Plug all devices back again after system booting. All of devices should work now.
I tested both on my X60s working even if it seems rediculous.
Lenovo promised to send me a new docking; however, I don't think it will help unless new BIOS is released to solve this issue.
Note: the kep point is you have to wait to plug all devices back to docking after system boots.
Good luck.

Anyway to bypass a broken USB port? I got an error saying that my USB device was drawing too much power and had to shut off.

I have a macbook pro. I just upgraded to Mavericks last night hoping this would fix the problem, but it hasn't. I received this error message and now none of my USB ports are working. I researched some and people have told me to reset the nvram, yet it is still not working. I have seen Thunderport docks that include USB ports on them, but they cost around $200. Just seeing if there is some sort of adapter or clever way to get around this problem? I mainly use my USB port for a Wacom Tablet. I was thinking about replacing the logic board, but that would be my last option. also, when i plug my phone into one of the USB ports, it shows that it is charging my phone, but it doesnt show up on my computer.
thank you!

You may see if you can get a rise out of it by use of another reset...

Generally when combined total of items plugged into USB bus, where
ports are powered from one internal source, is too high, you'd get &
use a USB powered hub. This has a power adapter, so the USB bus
in computer does not need to try & support more load than it can.
Avoid charging an iPhone, iPad, etc from the computer, those little
USB chargers are better. And the Wacom tablet may be OK when
the computer is running on the power adapter.
The computer may not need a new logic board, but an adequate diagnosis
should be done before any major efforts are made into a big takeapart.
If you are in the USA or Canada, an Apple Store with Genius bar could
help determine the issues in the portable computer, if you check ahead &
set an appointment to discuss and diagnose this issue. This should be free
however the repair of any issue is another matter, and would cost. You can
take the unit anywhere qualified certified authorized trained Apple specialists
hang out, for further testing and repair. Or trust a reputable repair company
at a distance, and mail the computer away, after contacting them for details
on how they prefer to set up the repair, and how they want it shipped.
If you do get it repaired for one thing, while it is open consider items such as
a new larger capacity hard disk drive, etc. Otherwise a little while later, it may
be due for one, as they will fail. Even the fancy SSDs can fail quick enough.
Hopefully you can get USB to work good enough to further troubleshoot.
Good luck & happy computing!

USB PORT REPLICATOR WITH DIGITAL VIDEO JUMPING BETWEEN LAPTOP SCREEN AND LCD

Hi,
I have an E330 connected to the above port replicator and I am having an issue where I could be working away on a document and all of a sudden the screen on my LCD freezes and goes blank, then my laptop screen boots up for about 3 seconds then it switches back to the LCD.
I have noticed that it only seems to happen when I am either using the scroll wheel on the mouse or clicking on the mouse button.
Any suggested fixes would be welcome
Graeme

This sounds like the USB dock is dropping off the USB bus and then reconnecting. This could be a problem with the USB 3.0 hub in the dock.
Lenovo have made a firmware update available for the USB 3.0 hub in this dock, that could solve the issue:
http://support.lenovo.com/en_GB/guides-and-manuals/detail.page?DocID=UM014961
It is also work making sure your USB 3.0 host controller drivers are up to date if you are using Windows 7. Links to the latest USB 3.0 HC drivers can be found here:
http://kb.displaylink.com/315
I *think* it is an Intel USB 3.0 chipset on this laptop.

USB ports won't work

Hi, I recently bought a Probook 4441s-445TX. I installed Windows 7 Professional 64 bit on it but I couldn't get my 2 USB ports on the right side of my laptop to work. I looked into this and it seems like HP Probooks series have similar issue as well. The USB ports on the right (USB 2.0) don't work at all, they won't recognize any devices nor they can recharge any devices via USB cable.
Any suggestion? Am I missing a driver here (I checked Device Manager and it says I miss one driver but it's unknown device with Hardware ID "ACPI/HPQ6000" which I still couldn't find the driver for it, btw, but I don't think it has anything to do with the USB ports.

Hi:
If the notebook is still under warranty, it is time for you to call HP technical support.
Good luck,
Paul

What's up with USB Ports in Mac OS???

One of the things I loved about my old TI-PB is that you could plug in any digital device and it would truly be "plug and play" (as opposed to my PC's which were a pain to get working correctly.) In that regard, those "Mac vs. PC" TV ads WERE correct...Until now....I have a brand new MBP, and I can't use my HP Scanjet or my Nikon Digital Camera. System Profiler "sees" the devices on the USB ports, but they don't work. I searched "USB" here and some one mentioned that while Rosetta can translate applications for the Intel chips, Rosetta cannot translate "drivers." WHAT!? A Mac with a "driver" problem??? Heck, that's inheard of, and one of the reasons "I Switched" several years ago....So guess what? I bought a copy of Windows XP, dl'ed BootCamp, dl the HP software for Windoze and the scanner works fine in WIN-XP....For the camera I didn't have to dl anythin else...It works fine with the "Windows Camera and Imaging Wizard."
Sorry for the rant, but this is ridiculous that after spending $$$$ for the MBP I had to buy Windows and have to boot into XP in order to use devices I used flawlessly for years. HP was quoted in MacWorld that all their stuff would work fine with the new macs...Not So...I dl'ed their "HP Image Zone" software marked specifically for intel-based macs to no avail.....
Did I miss something? Is their a fix (firmware, OS, anything!) out there or on the way?? Any Advice would be GREATLY appreciated....

In other cases, you may need to download the latest firmware or driver updates for your camera in order for the device to be recognized and operate properly with Mac OS X. Check your manufacturer's Web site for a download.

Equium A200-26D - Error code 19 in device manager on USB ports

I have decided to try Windows 7 but the usb ports don't work in device manager all the usb root hubs have a yellow triangle and the device status says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".
I've tried uninstalling them through device manager and restarting the computer and downloading and reinstalling the vista drivers, as I can't seem to find Windows 7 drivers, but none of that fixed anything. I was wondering if there was anything else I could try or if I could get a link to the right drivers.

Firstly I'll state I know first hand that sarcasm and being generally rude via a forum will not get issue's resolved any faster , but I feel raped by Toshiba and 3rd parties and obliged to post
Lets start at the beginning , that's usually the best place .
On 2008 I bought a Toshiba , being a 3D artist I thought this would be a great investment .
But sadly I was wrong .
Purchased at PC WORLD GLASGOW - for 450 GBP "just for geographical reference "
Once I had opened the shinny new box and carefully unwrapped the dangerous contents , I switched on my laptop with bated breath........................
Guess what ?
3 dead pixels not at the side nor the top but right in the middle .
Now you can understand my concerns being a graphics artist , but this issue was quickly resolved "After a Huge fight with PC world because there generative manager policy for today was
" You cant return Unless it had 5 or more dead pixels "
" WRONG ANSWER MY FRIEND "
Ok ,so excellent they swapped it ,after I had to fork out another 50 GBP for an upgraded version because they had none in stock ! .
So effectively I got another machine that I didn't want for extra money .....superb
Ok so, I get this machine home , TOSHIBA EQUIUM A210
everythings fine and dandy for about 1 week
A) DVD DRIVE
-At first I notice the DVD drive acting funny , reading discs then not reading them it lost all function except the ability to read ,ok not a problem I have a home PC that can burn discs ,I'll let that one slip .
B) PAINT FLAKING OFF
the paint on front panel "where the lights are " starts to flake and fall off .
-Ok I'll put that down to wear and tear but its still only a month old
C) OVER HEATING (MEGA) Burnt my daughters arm .
- As I mentioned above I do graphics , this machine main purpose was to browse the internet ,maybe a few world docs , not render out 9 million polyz , I fully understand this concept .
but it started to overheat , I'm not talking about a little bit warm , I'm talking full on ,that much you could cook an egg on . not only did the machine but also the power pack . remembering this machine is still less than 2 months old .
The heat was that intense that it burnt a perfect rectangle onto my 3 year old daughters arm .
-arguing with my wife not to sue for faulty/dangerous electrical goods I phoned customer services up , and spoke to a very nice gentlemen that was happy to help .
Excellent Laptop getting picked up and taken away to get fixed ----SEE CUSTOMER SERVICES NOTES .
I was that considerate that I re-formatted the machine ,dragged all the essential tools onto the desktop ,you know control panel , system setting ect . and even made a nice jpeg schematic where the faults are "because I know how much off a pain in the teeth it can be working on the tech side and anything I can do to help "
1 or 2 weeks later I get my newly refurbished laptop back .
Superb , or so I thought ...................
Jump forward 6 months later , just before the manufactures warranty runs out IRONICALLY
Inbetween random faults and the paint starting to fall of AGAIN ,
The machine starts to switch its self randomly off ! without prior warning .
"Ok , maybe it was just a system fault , I'll restore .
Nope still doing it , Maybe its the battery not holding charge and it's struggling to detect it ?????
Nope its still cutting out ................
May I also add after the return off the machine ,which in my professional opp " YOU JUST REPLACED THE SHELL AND BLEW THE DUST OFF " . --------- PLEASE POST CUSTOMER SERVICES NOTES ...."maybe I'm wrong ?"
Now due to the machine randomly switching it's self off it caused massive corrupt sectors and chkdisk errors and loss of data ."some of which was costly , but functionally I'm an intelligent spices I managed to back MOST data up .
Ok so not a problem It's getting old (1year and 3weeks to be exact ) , its generally used for Internet ,theres some work and some personal photos ,nothing thats going to rock your world .
I'll use it for that .
OVERHEATING AGAIN :
Now this can be caused by dust ,also quoted by one of your ignorant members of staff .--
!!!!but this was caused by another mass produced product ,quickly shipped out and grossly missing product user safety testing .....................
HOW DO I KNOW THIS ::::::::::::::::::::::;
Mainly because when you Google Toshiba A210 it hits over 3 million user faults / problems
"Excuse me for sounding like one of your tech guys , but I used google search string to legitimize the search "
and the evidence is there .
Ok so its overheating ,thats maybe why it keeps cutting out ?
not a problem ,not UNTILL TODAY .
"sorry it took so long to get here "
So today My daughter "now 4 " is playing on nickjnr home page "Carefully avoiding the hot lava that pours from the heat vent at the side , and it cuts out again ....
Goto Switch back on
" A method we now call " PULL THE PLUG OUT AND SWITCH ON AND OFF 5 TIMES ,STAND ON 1 LEG & PRAY .............
and up pops this
some here may have seen this before ...................
THIS IS CAUSED by poor programming and bad development
BIOS :
Its called BIOS lock "and yes i did try , TOSHIBA , ADMIN , 12345678 blah blah blah " effectivily the machines decides to encrypt or maybe not encrypt a password , just depends how it feels that day .
Toshiba know about this fault and offer a fix ##maybe at a price ,just depends on what sales rep you get ##
This is the whole point of the conversation so If I lost you with bad grammer / spelling at any point in the post please PAY ATTENTION this is the IMPORTANT PART
================================================== ==========================
I searched ways to brute force , fix , remove battery and so on when I decided enough was enough this machine is faulty -------I'm going to give legal jargon here just so you know where on the same page .
The Sale of Goods Act 1979 as amended
Goods must be:
???????????????¢?????¢??? ??????¢???¬?????¢???????? ???¢fit for the purpose they are made for

???????????????¢?????¢??? ??????¢???¬?????¢???????? ???¢have no minor defects
???????????????¢?????¢??? ??????¢???¬?????¢???????? ???¢acceptable in look and finish
There's others if you would like me to continue ,even better ones but I'll just use this one right now , just to be polite .
Your PRODUCT was faulty since it left the covaor belt , your people should have picked up on this when it got returned but I'm sure they may have been busy ! .
Now we can argue these points and justifications but ontop all that .................
this hurts the most .
Today I phoned - TOSHIBA CUSTOMER SERVICES :
"Sorry Mr Scott for the problem you can either wait and we'll send someone out to fix it , OR I QUOTE you can take it to PC WORLD and because there TECHGUYS they will be obliged to fix FOR FREE due to it being purchased there .
I PHONE SEVERAL PCWORLD NUMBERS UP and bounced there calls try to get an answer before someone on the end says # " Maybe you should take into your local store 15 miles away " ----
great thinking sherlock
OK
I GOTO PC WORLD : Yet another human with the capacity of a moth , 300 million sp3rm and that's the one that got threw .
TELLS ME " We don't do that because we are are not obliged to fix it " ,"But i have a piece of paper with a customer reference that a trusted toshiba services man gave me
Ok hold my breath walk out and go and phone TOSHIBA up again not a problem ................
This is where it gets good , I phone you after speaking to another 4 or 5 people on your side .
When I get to speak to someone that's happy to help but at a price ,who decides to become law and Order roled into one, the conversation gets silly and YOU throw potential threats and jargon around #congrates your grease monkey can read off a pdf document ,well so can mine ,but fortunate she has practiced Law for the last 10 years and is pretty accurate ...
but again I said Polite so here it is :
YOUR QUOTE TO FIX YOUR PRODUCT ::: 100 + GBP give or take just depends on how constructive your people decide to be that day ...
So here is my QUOTE
PHONE CALLS
TOSHIBA 8 : average length 20 minutes 8 GBP
PC WORLD 4 @ 1.50 min 15 GBP
GAS / FUEL : 15 GBP
Loss of Earnings : 90 GBP @ 5 DAYS 410 GBP
Damages " DO YOU GET MY POINT YET ? "
As I mentioned I'm a reserved man ,but getting shafted by TOSHIBA from all angles does has Limits
Now what I would like to see arriving on my front door is a new brand spanking Laptop with " WE ARE SORRY " note attached .
but for some reason I don't get that impression ?????
I'm hoping we can remedy this issue in a sensible fashion ,
If we can't , I do have a great idea of posting a YOUTUBE video of me destroying your product with several sharp objects , counter productive maybe ,but when it hits a million hits I'm sure I will get another company to give me a laptop out the kindness of there heart ................
Now for forum posters I apologize for raining on your day , to TOSHIBA please try to understand why I'm a little bit upset .
Have a nice day
PEACE .

Right Side USB Port not working

My USB port (closest to the screen) is not working? And what is an IR Receiver in my USB port?

Hi everyone,
     I recently found out that my USB port, closest to my screen, is not working. Before I called Apple Care for help, I performed a PRAM and a SMC RESET, which unfortunately did not work. I called Apple Care and they help me troubleshoot simple resets such as, shutdowns and restarts. The representative I spoke with conluded that the physical hardware has an issue and must be brought to the Apple Store for a diagnosis. I called the Apple Store to at least budget the fee for getting a USB port fixed and it's about $300.00. I never dropped my macbook or had any sort tactile encounterment with hard surfaces by dropping or hitting. I don't understand how my macbook pro would be physically damaged. I then thought maybe my software was out of date (right now I am running 10.9 Mavericks) or I forgot to do the minor software updates, but I was at a lost again because my macbook is up-to-date. I searched for further help and found a way to monitor what's plugged into my usb ports. (I read in the apple forums that a girl had nothing in her usb ports, but upon looking at the System Information> Hardware> USB, that the macbook recognizes that there are drives in the ports) I looked at my ports; one is being used by wirless mouse (the port that works) and the other (the port that doesnt work) is being used by an "IR RECEIVER". Now, is the IR Receiver actually using that port and that's why my macbook cannot recognize other devices inserted into that port? Or is the IR RECEIVER suppose to be in that port and that the hardware for that port is simply damaged (which would mean I need $300.00 to get that fixed)? I know this is a lot, but someone help me?

I can help with the "IR Receiver" part of your question. That's the piece of hardware inside older MacBook Pros (MBPs) that lets them work with the Apple Remote. "IR" is the standard abbreviation for "infrared," the portion of the electromagnetic spectrum used by remotes for many common devices (stereos, cable boxes, Apple TVs, etc.). The remote sends a coded stream of IR pulses; a corresponding receiver in the target device "sees" the infrared light and decodes it. The MBP's internal IR Receiver sends the received signals to the processor via USB through an internal hub.
The most recent MacBook Pros have dropped the IR receiver and no longer work with the Apple Remote.

USB ports don't work after resuming from standby with Windows 8 on X230 tablet

I have just done a clean install of Windows 8 on my X230 tablet. Before installing Windows 8 I installed the most recent BIOS for this machine (version 2.50). After installing Windows 8 I installed System Update from the Lenovo Website and downloaded all the recommended drivers and other files. I've also installed all the latest Windows 8 updates.
Here are the symptoms of my problem: After resuming from standby/sleep mode, my USB ports do not work. My computer has two USB 3.0 ports and one USB 2.0 ports. All exhibit the same behavior. After resuming from standby mode I have tried inserting both my mouse and a USB thumbdrive, but neither are recognized. After restarting Windows, the USB ports work again... until I resume from standby mode again.
I hope there is a solution to this issue. It is very frustrating.

Thanks for the suggestion about tweaking the "Allow this computer to turn off this device" feature. I un-checked that box for every entry I could find under "Universal Serial Bus Controllers" in the Devide Manager. Unfortunately, the same symptoms of my problem persisted.
I went back and looked at the README file associated with the BIOS 2.50 download on Lenvo's support site. At the bottom of the file it gives a "Summary of Changes". Under version 2.03 of the BIOS (the version just before version 2.50), it says:
- (Fix) Fixed an issue where USB device might not detected when system resume from sleep mode.
This indicates that Lenovo support was already aware of such issues. The problem was intended to be fixed in version 2.03 of the BIOS. However, the issue persists on my machine, even with the latest BIOS.
Hopefully someone from Lenovo can comment here.

PLease HELP!!

Hello jounin85 and welcome to community,
Kindly unplug all USB devices connected to the USB port then go to device manager and uninstall all USB drivers
Download the USB driver and install it.

IPhone 4S won't charge anywhere in my house if its powered on, only off - but will charge by USB port in my car. Help!?

I know part of my question is a repeat of others, but - I can't find one on the boards that matches mine exactly.
Basically, many months into having my phone (I'm updated to the current software), my phone is refusing to charge by wall sockets. I thought it may have been a specific socket, so I tried others. No luck. I tried connecting to one of the power strips I my room, again, no luck. With my last attempt, I plugged it into one of the USB ports on my new power outlet block (has two USB ports), AGAIN, no power.
I switched and also tried 4 different cords. No change.
At this point, after an hour of extreme frustration, my phone had died. So, I plugged it in for you-know-what's & giggles. Within about 15 minutes, my phone mysteriously powered on with about 5% battery - but, NO CHARGING SYMBOL AND NO CHARGING ONCE ON! I even tried almost every outlet, in a two story house, while switching between outlet, power strip, and USB ports on the power block - to no avail!
I was stunned, so as a last resort I went to my car. I have a 12v universal USB charger, as well as a USB port that is built into the car. They work...
As you can surely see, I'm extremely frustrated. Since my fiancés iPhone is broken, and my mother (whom I do not live with) is a severe heart patient, and currently sick - I need my phone on & running out to let the phone charge in 20* weather and going out to check it every hour, is not ideal.
So, ultimately, if anyone can explain to me if they believe it could be a circuitry issue, battery issue, or phone issue - also, explain as to why it will charge by two methods in my car, but not any means in my house; I would be greatly appreciative!
Thanks!
Typing this as my phone is about to die -_- .

Got the same problem
last night I tried to charge my iPhone 4 with my ps3 USB ports, suddenly it began to stop charging and start again like on/off so i unplugged it from my ps3, now it wont charge with my ac adapter or my macbook, however it charges on one computer that ive build my self. if my phone turn off due to 0% battery it will charge anywhere until it got 5% power
since it charges means nothing is wrong with the phone i think, so I will buy a new USB cable, or borrow one to see if it works. most likely the usb cable causing the problem for both of us

3 USB ports missing +5 Volts., HP X18 1027CL Laptop, Win7, USB powered cooling fans, no message.
