One USB port does not work with external Disk or USB key
Hello,
Back to my iMAC there is 3 USB port. The second one - in the middle - does not work pluging an external Disk, an USB key or an iPOD nano. However it works well connecting a Wacom tablet.
Is there an explanation to this behaviour ?
More the keyboard is plugded on USB port 1 and the mouse on the keyboard. Time to time - especially at reboot - I have to unplugged the mouse and plugged again it in order it works.
In advance thank you for your answers
Regards
Since it does not work for three different devices, I will assume it is not something simple like a faulty USB cable. Since it does work for one device, I will also assume that the port is (at least partially) working.
As a test to narrow down the cause, I would try restarting from your Mac OS X installation disc (insert disc and restart with the C key held down).
At the first Installer screen (after language selection), go up the menu bar. Under Utilities, select to run Disk Utility. Now, connect the USB drive into that center port. Does it appear in the Disk Utility sidebar?
Please post back the result...

USB port does not work with a screen
Dear All,
My manager has a MacNook Air 10.8 and he is using a large 27'' Apple screen.
He connects the screen to the MacBook Air with a cable which has 3 connections (USB, power, Tundetoh)
He reported to me, that some time, he connect a mouse or a keabord to the USB, at the back of the screen, the two devise does not work, while it works when the devise are connected to USB port of the MacBook Air.
His Macbook Air software are uptodate.
Does you know how to make working the USB devise connect to the screen?
And what does make those trouble?

External USB HD does not work with HAL:
External USB HD does not work with HAL:
From the last 10 days the HAL auto-mount with ntfs-3g file system of my external hard drive does not woks.
But the manual mount procedure with the command mount -t ntfs-3g /dev/sdb* /mnt/XYZ works.
I've followed the instructions in the wiki: http://wiki.archlinux.org/index.php/HAL and the system has worked up to the last kernel or HAL update.
My fat32 usb-stick works without any problem.
If I try to open the device with KDE it appears an error popup wit this message:

Do you have some idea ....
Bye.I have done the following:
Downloaded the patched hal version.
used makepkg in /abs/local/trunk/ to create a pkg for pacman
used sudo pacman -U pkgname to install it.
used sudo nano /etc/hal/fdi/policy/preferences.fdi to create the fdi file with the following content:
saved the file and removed my ntfs entryes from fstab and rebooted. and still there is no automount off ntfs partitions.
have i done something wrong?
br fjodork
WARNING: what follows is a guide of what did work for me, I'm still in an early stage of learning linux, so please correct me if anything of what follows is wrong/dangerous/stupid. As I said, this worked for me, it's not pretty, since I was learning each step on the fly and I'm sure there are better ways to do this.
So fjodork, you seem to have done the the necessary steps, though i couldn't get it to work until i first removed hal without dependencies
pacman -Rd hal
it will give you some warning about the dependencies, ignore it since we are reinstalling hal in a few steps.
First i tried to follow Raymano's link, obviously it showed me nothing in the browser so I thought it might be a broken link.
So I downloaded the source tarball from here http://hal.freedesktop.org/releases/hal-0.5.10.tar.gz
unpacked it changed the /tools/hal-storage-mount.c as per Milfadoodle's instructions.
at first I tried to compile directly from source, the process would finish without a glitch though after reboot nothing changed, as if hal weren't
installed, i guess there were issues with paths. anyway read on
Then repacked the source in tarball, copied it to /var/abs/extra/system/hal and modified the PKGBUILD as follows
makedepends=('pkgconfig' 'gperf')
options=('!libtool')
install=hal.install
source=(${pkgname}-${pkgver}.tar.gz #removed url so makepkg looks in the current directory for the tarball
hal
hal-policy.patch
cryptsetup_location.patch
hal-0.5.9-hide-diagnostic.patch
ntfs3g-valid-options.patch)
md5sums=('6641c30a27c00485c6accac5110ff911' # replace with md5sum of your package's sourceball (run md5sum filename)
'882f67668cb14a0a9e4a27ef22278027'
'5ba8b610aa9763a5f42b9f7cbd7a86ad'
then makepkg (i had to add --asroot, don't ask why
and finally pacman -U hal-0.5.10-1-i686.pkg
another reboot and everything worked without a glitch!:D (yeah i know i still haven't got rid of the reboot mentality )
I have also put the policy files as per the wiki instructions.
PS: I know this is a dirty way to getting things done but as i said, I'm just starting
If anyone could comment/correct/explain this post I'd be more than happy, the automount issue was bothering me for about a month now (you'll say why do I need ntfs in the first place? well, I only recently switched for Linux as my primary OS, these are some relics of the M$ era -
Hi I have problems with not working USB ports. It used to work. I downloaded actual drivers at msi.com for my gaming notebook GX 60 Destroyer and now my USB ports does not work. What should I do?
What driver have you updated?
Try to do an EC firmware reset by removing the battery and the AC adapter then put the battery back with AC adapter attached.
Same questions like Pegasus asked, does all ports not working? which one exactly? What OS are you using?
Have you done any changes to the system? (for example: self-install OS or changing OS) -

Apple USB keyboard does not work with one internal usb port
Hi everyone,
hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
After searching the web on such problem, I tries a few things such as:
I tried the keyboard on another computer (windows): works fine
I tried usb stick and external DVD reading on the left internal usb ports: works fine
I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
I tried the SMC and PRAM reset : nothing
Any idea ??
Thanks
GuillaumeI'm facing the same problem, found any solutions ?

Try uninstalling all USB hub devices from the device manager and reinstalling them again, particularly the keyboard's.

Hello all,
I am writing to you hoping that one of you may have an idea what's wrong with my beloved w510.
A few hours ago the usb port (on the back on the right side) where I plugged in my external mouse stopped working.
In the Lenovo part list it is referred to as "usb Sub card yellow".
It just does not recognize a mouse nor any usb stick or external drive. I have already reinstalled the usb controller
but it didn't make any difference. (I think the driver is only for the usb 3 hub on the left side of the notebook)
when I plug in the external drive the lights of the drive start "flashing" same for the usb stick, but they are not recognized as drives..Same for the mouse. The lights go on, but nothing else works.
Probably its all my fault, but I don't know what else I can try! Please excuse my bad English...!
Hoping that somebody might be able to help me...
PaulI have a reproducible test for this issue on my W510.
1) Plug in a usb mouse into the rear usb port and ensure the mouse is working.
2) Hybernate the system.
3) Resume the system.
4) Confirmed the mouse does not work.
5) Disconnect and attach the mouse to one of the left usb ports and confirm the mouse works.
6) Disconnect and attach to the rear usb port and confirm the mouse does NOT work.
7) Restart the system and confirm the mouse still does NOT work.
8) Shut down the computer (a full shutdown, not standby or hybernate).
9) Power the system back on.
10) Confirm the mouse is now working in the rear port.
I can do these steps over and over with the same results regardless of whether the AC adapter is plugged in or not. It appears that the data connection does not work after the system is resumed from a sleeping state. I have the latest UltraNav driver and utility and the latest power management updates.
Oh, and one more test. Hybernate the system with nothing plugged in, then plug in a mouse into the rear usb port when the system is presently hybernated and then power the system back on. The mouse will not work and rebooting doesn't correct it. Only a full shutdown fixes it. -
My Garageband does not work with Symphonic Orechestra or USB Boombox
I have two Macs: the main one is an iMac with Intel Core Duo 2 GHz, 1.5 GB RAm and 250 Gb HD, with OSX 10.4.8, and all the latest software upgrades as I download them as soon as they are available. The secondary Mac is a normal iBook G4-800 with 640 Mb RAM and not always the most recent plugins, but since a few days also the latest ones.
I premit I do use GarageBand to produce professional level music and in time I bought several new music features. I am a Mac user since ever and I never (I say again NEVER) uploaded any software (or loop) who wasn't regularly licenced and usually bought from Applestore itself.
NOW THE PROBLEM:
Since I sold my old iMac G5 and implemented my CoreDuo I experienced a problem with Garageband: the external plugins for Garageband (such as the old and excellent "East West Quantum Lightning Symphonic Orchestra" but also the very recent USB "Classic Boombox" and "Ethnic Boombox" are not working. Those software instruments does appear correctly in the menus, but does not work. When I try to select them it appear this sentence (in italian, I will try to translate it approximateively):
"the plugin is not available. To add this loop using the same sound you heard in the browser loop, press the Option key and drag contemporary the loop in a new track"
This it happens all the times I try to set an instrument from EastWest or USB plugins from my iMac. As to make a confrontation, I installed the same softwares on my iBook and they work perfectly (with the only exception that I can't work from the iBook since is far too slow for me to use it with some profit).
Someone an help me or explain if there is anything I can do to fix my problem?
East West said the pluging should work (and to be honest it works correctly on the G4 as it did work properly with the G5). I own the USB software just since a few days, so I didn't ask them yet, but since is not just them, I guess is something else and do not know what may be the cause.
Some of you do have some hint or idea?Yep, I understand...
This is the final news I needed to get to complete my answer... I confronted myself the italian store and the US one and in the US one I didn't find this product...
As for the NI software, was so good that I just bought back my good "old" iMac G5 and will exchange it with this my Intel Mac. The G5 2 Ghz was good, performing as this new Intel (at times I even got the impression was more performing, but I believe is just an impression) and surely didn't have so many 3rd parties problems.
Meanwhile I filled every forum of NI and USB with my questions about the compatibility... and maybe I will be back to an Intel Mac when all would be OK, I'm not in a hurry!
By the way I had a listen to your work: GREAT!
You may hear a sketch version of something we did work on with the NI piano and choir sounds, while the alto sax is played live and the other instruments are from Apple or real keys (yes, we mix a lot of things):
http://www.garageband.com/song?
while here is a track where we did use both the Orchestral sounds of Garageband (and some of it's loops, mixed with some good old programming) together with some NI sound:
http://www.garageband.com/song?
We do not often use orchestra if not as here and there (other than in some work as this last one, but is not so frequent). Hope you may like our little works! -
I noticed that one USB port(All other ports appear to be working)in the back of my Mac Pro does not work.
Aside from taking my Mac Pro in for a repair, is there any other way to fix this problem?You can always try resetting PRAM and NVRAM…

USB Camera does not work with iChat
Hello,
I'm having a terrible time getting my ToUcam Pro II to work with iChat. I downloaded the iUSBcam program. That didn't work. I downloaded the program Macam, and copied the proper file into the Quicktime Library (as suggested) and that didn't work. I downloaded IOXwebcam, and got an error stating that it wouldn't run due to the fact that it didn't have the proper security settings. Sigh.
So... what am I to do?
I'd like to buy a webcam that does, actually, work with my 8 month old Mac Pro 4 core mac desktop, but the iSight camera is ridiculously expensive. Any other suggestions would be appreciated.
BradAn X-box 360 cam will do it although not in that list.
Anything that is USB 2.0 and marked UVC compliant or Vista Certified.
Be Aware some Mac Keyboards do not have USB 2.0 ports.

USB hub does not work with iTunes
I have been trying to add USB ports to may Mac's and am not able to synch through the hub. They are hi speed 2.0 USB hubs by Rocketfish and Belkin. iTunes locks up until I remove them from the USB cable (spinning color wheel) and then iTunes goes back to normal. I have tried with both my 24" Intel iMac (Metal one) and a new 15" Macbook Pro. When I use the USB port on the Mac iTunes works great. There seem to be a ton of USB problems posted and zero answers on how to correct. I have tried with an Color iPOD, iPhone and an iTouch to no avail. Having a couple of USB ports won't work in my situation. Anyone know if Apple has posted a workaround or a real fix anywhere.
Thanks, I missed where I posted But I tried with my HP - Same issue. I think others have had this. I believe that iTunes is hit or miss on Hubs. I wish I could figure out what makes them a hit - instead of a miss.

Lightroom 4 does not work with external editor
Hi All,
I am using Lightroom 4 and Photoshop elements 9 on Mac OSX. I upgraded from LR3 to LR4 a few weeks ago and since I updated I can not anymore use Photoshop Elements 9 as external editor. I did all setups, still does not work.
Anyone has an idea what could be the issue or did anyone experience the same issue?

E3200 - USB port does NOT work for more than one device
We needed a new router that had the dual band connectivity as our previous router stopped working properly when we started using a baby monitor operating on the same 2.4 GHz. The choice was between E3200 and E2500. We chose the E3200 mainly because it also offered a USB port. We were hoping to use that to connect our printer and two external drives (thus bypassing our old desktop that's been working as a server). However, it turns out that the USB port on E3200 does NOT support USB hubs! So, you can ONLY use ONE device - either a printer or one external storage drive. That wasn't really clear at all from the description. I feel like we wasted the extra $50 hoping to get functionality that just isn't there. Can't believe that in this day and age, Cisco thinks we all have only ONE USB device we might want to connect to the network! The router itself is fast enough, but the extra $50 for a USB port that doesn't do much and some speedboost phantom ability is just not worth it.
Just to save time to you all, after numerous attempts to install a USB hub to my E3200,
I wrote to Cisco Customer Service (live chat) and I specifically requested how to set up the usb hub or the virtual USB port and they said that they do not have a software to install a USB hub.
Hope this help
