USB trouble...

I have an intel iMac (intel core duo 2 GHz) and I upgraded to leopard with no problems for nearly a month. Recently I experience an issue with the USB drives and all that are related to it. I am using elgato EyeTV, an external USB hard drive, iSight and bluetooth mouse and keayboard. Now I cannot operate all of them at the same time. If I have iSight acteve (ichat or photobooth) then I get an error from the EyeTV that there is not enough USB bandwidth. And if it is already working, and start iChat it shows a message that the iSight is in use. Oh and the external USB volume almost never mounts.
I used to have the iPod, the Hard Drive, the keyabard and mouse and the Elgato EyeTV and now... Well I can reinstall Leopard, but is it hardware or software issues.

It is not your hardward it is Leopard. Check out this thread http://discussions.apple.com/thread.jspa?threadID=1206301&tstart=0 many other users are having the same problems including myself.

USB troubles wit notebook satellite A135-S2386

Hi, I own a TOSHIBA Satellite A135-S2386, which began with troubles of USB ports, none device attached at any of these ports was recognized, then the Windows Vista was reinstalled, with all the drivers included in the DVD supplied with the notebook, the trouble continued. I downloaded the BIOS update (ver. 1.60), and was installed too, the current version until was 1.20, now is 1.60. The trouble with USB ports remain, therefore, I need to know any recommendation of you. Any who has any repply can contact me at [email protected] Best regards, Ing. Humberto N. Rdguez.
Solved!

If you have restored the hard disk to its original out-of-the-box contents using Toshiba recovery media and also flashed the BIOS, that leaves only the hardware as the cause.

Nforce3 AMD board USB trouble?

hi i got a trouble...
i cant make my front usb and my 2 extend usb port working... my 4 ports plugged directly on the mainboard works... but others dosent work... they are on irq 21 and 22... any have an idea... they just dont work. no power.. nothing...
thx

I had the same problem. There are allready sollutions in this forum but maybe to hard to find. You have to leave the 9th Pin empty. Do not connect it to ground

If your USB onboard connector looks like this leave the X unconnected.

4th gen ipod usb troubles

ok, so i bought a 20GB 4th gen. iPod off ebay and i can't get it to work with my computer. I have a Gateway laptop with roothub usb. My computer will detect the iPod, but not my iTunes. And it has trouble charging. I think it is a compatability with my computer so now what can i do? I don't really want to have to upgrade my computer just for my iPod, but as far as I know the iPod is the only device that will play the AAC iTunes files.

Apple created the stupid AAC file format to annoy Windows users.
Change your settings in Edit > Preferences > Advanced > Importing ~ to "Import Using 'MP3 Encoder'" - not AAC. If you wanna send music to a friend over AIM/MSN/Yahoo or whatever and they dont have iTunes, it's annoying, MP3 is more globally accepted.
So your iPod works with your computer, but not with the iTunes.
Things to try:
1) Re-install iTunes
2) Reset iPod
Good luck and reply back soon!

KT3 Ultra - USB Trouble

Hey, im having some trouble getting the USB-ports (The 2 on the board, not the extra on the "cards", they are lost) working on this m-board.
First of all the USB devices where disabled in BIOS but that is fixed.. but here comes more trouble. WinXP found new devices when i started the computer after i enabled the usb in bios. But, i cant find any drivers for "Universal Serial bus" , and its under "other units" in the device manager. But.. the "VIA Rev 5 or later USB Universal Host controller" and USB-Hub is found, drivers found and prolly working.
Anyway.. what should i do?!
Excuse my bad english and bad translatíon.. im swedish

"...and its under "other units" in the device manager..." It should appear as a separated item after Net devices or Net adapters. Perhaps could work deletting all USB items in Device Manager, reboot and let W XP reinstall all of them.
Did you load SP1 for W. XP ?

Z77A-G43 USB troubles.

Hi there,
This week I did a build for one of my clients for wich I used a Z77A-G43 board and I'm having trouble with most of it's USB ports. Planned for the build was an Asus P8Z77 WS board for this workstation, but since my supplier couldn't deliver on time I was forced to pick another, the Z77A-G43 was recommended to me by my supplier and after reading a lot of positive reviews I gained enough faith to just go for it. Unfortunatly, I have ran into trouble with the board... :( Just my luck!
The USB 2.0 ports on the back function fine, but the headers on the mainboard and de 3.0 ports (on the back as well as on the 3.0 header) give me alot of headache.
The problem was noticed first when I tried installing the OS with a USB stick. First the install failed almost imediatly, telling me it couldn't find the medium. I thought it probably had to do that the install of the OS didn't have drivers for the USB 3.0, so I tried the USB 2.0 port on the front of the case (connected to header on the mainboard). This time the PC wouldn't even POST normal, no errors either.... it just hang there. I'm also unable to enter setup with a USB stick in one of the ports connected to a header on the mainboard. If I plug the same stick into the back, the system POSTs fine, can enter setup, and installed the OS this way. All is fine, as long as I don´t connect mass storage media to the USB headers on the mainboard.
When the OS was installed, I could connect a drive to the front headers and Windows will recognise the drive. I´m even able to read from and write to the drive. However, if I leave the drive in and reboot the PC, I have to take out the USB stick to be able to post (same thing if I leave a SD card in the reader by the way). Switching off legacy USB support in the bios lets me POST with storage media connected to the USB header, but if I restart windows with mass storage connected to the headers, it won´t recognise the drive once it´s booted.
This also happens with the card reader that´s connected to one of the headers. If I disconnect the cardreader and plug it back in with windows running, it finds the cardreader and I can acces my SD cards. If I restart the PC, it posts as long as legacy USB support is turned off (with it on it hangs at the POST), but as soon as windows is loaded, the cardreader isn't recognized and it doesn´t see the cards untill pysicaly I reconnect the cardreader. The bluetooth part of the cardreader is recognized just fine though, and also the webcam connected to a front USB port will start just fine on every boot. Just don´t expect a USB memory stick or the cardreader´s mass storage functions to work.
Is this a known bug with the BIOS at the moment? Or is this a case of defective hardware and do I need to RMA the board?
Things I did so far to help it;
Installed latest drivers
Updated the BIOS to version 2.7 (including the Intel ME) at that point I realized the connection between the problems in windows and the post / bios setup problems with the front USB headers and mass storage.
System specs:
Case: Fractal Design Define R3
PSU: BeQuiet Pure Power L7 (530 watt)
Mainboard: MSI Z77A-G43
CPU: Intel i5 3470 Ivy bridge
Cooler: Gelid Tranquillo rev2
RAM: Crucial Ballistix 8GB PC3-12800 (1600 MHz, CAS8, Non-ECC, 2 sticks)
SSD: Samsung 830 128Gb
HDD: WD Caviar blue 1TB (7200rpm)
Optical: Asus DRW-24B5ST DVD ReWriter
Cardreader: Akasa AK-ICR11 all in one cardreader with bluetooth
OS: Windows 7 Professional
Hope someone can shed some light on this...
Thanks in advance,
Michiel
PS:
I'm sorry for my bad English, it's not my native language and am not used to having to write in it.

I'm not keen on trying to flash beta versions of a bios onto the board, if I'd brick it it would be my own risk. I can compensate for power outages by putting the system behind a UPS, wich I always do, but I can´t compensate for bugs present in a prerelease. It´s just a risk I´m not willing to take, especialy if the problem isn´t one that more boards of the same type have.
If it's not a known issue I think I'll RMA the board... I mean, if other boards of the same type are not bothered by it, by all means, they (my supplier) can send me another one that´s not plagued with these gremlins.
Mainboard has been run on a testbed outside of the case already with one DDR3 2GB stick (Kingston valueram), same result. I will check the CPU pins, but to be honest, I would be VERRY surprised if one of the pins would be off.
Thanks for your help so far, but I think this will be one for my supplier to take back. Hope I have more luck with the board they send back. Is the Z77A-G43 generaly a reliable board? Or would it be wise to request another board? I can't afford to having to tell my customer that the board I got back also failed... It will already miss it's deadline because of this, so I realy need to have a solution asap

USB trouble on k8NGM2-NBP new build

board: msi k8NGM2-NBP
cpu: amd 3800+
drives: single maxtor ide 80GB
ram: OCZ platinum 2-3-2-5 PC3200 512MB x2 (1GB) (slots 1 &2)
with the DDR voltage raised to 2.65+, detects at 400Mhz
psu: Antec 450 from a Sonata II
I get this board from www.mwave.com and start testing by connecting
components on my tabletop
The first post is OK. I set optimal defaults, reboot, then raise the DDR voltage so
that I see the RAM working at 400 Mhz, instead of 333.
Next I try testing with a bootable CD of memtest86+. I'm able to test without errors through test #4.
By accident I try memory testing with a
bootable USB flash disk. I get errors immediately. I then try the bootable CD again with an
external USB drive connected -- RAM errors again. Now I know that its the USB causing an instability.
So the board is OK as long as I have no USB ports inuse -- .
I don't continue on with the build, the next step being an install of FC5 linux, until I
know if this is an RMA issue or bad bios setting.
please advise and thanks

hello Kakarocht and Built2last,
This board has the nvidia 6150 northbridge with integrated graphics, which I'm using -- no addon video card for this build.
The bios is the latest, at 1.1 -- I checked the site.
I've been advised elsewhere that even with USB RAM errors I should go ahead and install an OS, since the OS can do integrity checks.
I don't agree with this and stand firm that there should never be any RAM errors, with or without USB connections.
I tried connecting to USB on the rear and with the onboard headers -- all gave the same bad results in memtest86.
From reading a few posts here very few posters test RAM in a tabletop build, but usually charge ahead and do their first
build in a case, then test after assembly. I don't do this anymore -- I did for my first few builds.
I'm going ahead with an RMA since I have confirmed that everything but the MB is good. I tested the RAM and CPU elsewhere.
ciao

PDA Palm syncing via USB troubles

kernel messages indicates a detection of USB device plugged in:
usbserial.c: Handspring Visor / Treo / Palm 4.0 / Clié 4.x converter now disconnected from ttyUSB0
usbserial.c: Handspring Visor / Treo / Palm 4.0 / Clié 4.x converter now disconnected from ttyUSB1
does this mean hotplug is working?
but trying these devices eg. '/dev/ttyUSB1' under jpilot and the PDA and desktop do not connect
/dev/usb/hid
/dev/usb/tts
are empty folders
I thought I was running static dev system but could devfs still be around
and if so what are some entries I should add to
/etc/devfs/conf

ty
my default 0.6 fstab entry is different than yours
usbdevfs /proc/bus/usb usbdevfs defaults 0 0
all permissions under /procs/bus/usb are world readable, do they need to be writable as well?
I'm testing connecting the PDA USB cable to machine and using these devices
/dev/ttyUSB0
/dev/ttyUSB1
are they correctly named?
usbview does find the PDA

Deep freeze +imaging = USB trouble

When we image a pc and then freeze the machine the first time you plug in a USB device it takes upwards of 9 Minutes to install the USB device.
After that first device is installed every device thereafter installs in less than 25 seconds. Once I reboot that first usb device once again takes 9 Min.
I realize that is Deep freeze doing it's job. Has anyone found a way to initialize the usb controller so that first time plugging in USB takes less time?
If I thaw the machine and then plug in the USB device and wait 9 minutes for it to install. Then freeze the machine. Every device thereafter installs within 30 seconds even after a reboot.
However if I take an image of this machine once USB has been initialized and put it on a new computer I am back to square one again. The first device plugged in takes 9 minutes until I do the thaw, plugin, and freeze trick.
Any help would be greatly appreciated.

IPod USB trouble!

So I have an iPod Touch Gen 4 and whenever I connect the USB cable to my iPod and Computer it just does nothing. It makes the little jingle when you connect but that's it. I can't access my files or charge my iPod. I'm pretty positive it's not the charger because I can charge it with the adapter. I tried updating the drivers but they're already up to date. The device status says, "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" and I'm just looking for a way to solve this and be able to charge my iPod on my computer once again. (My computer is a Windows 7 Home Premium Laptop) Please help!

See
iOS: Device not recognized in iTunes for Windows
- I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
However, after your remove the Apple software components also remove the iCloud Control Panel via Windows Programs and Features app in the Window Control Panel. Then reinstall all the Apple software components
- Then do the other actions of:

USB troubles with iMic?

I have used the iMic off and on for a few years, and I've noticed that sometimes it is recognized when I connect it to the USB port and sometimes it isn't. When it isn't, it is really frustrating! Today I started unplugging other USB devices and trying different ports until I finally got it to work.
(I was using the Sound Preferences panel to look for and select the iMic, and I was also watching in System Profiler)
Are there any "gotchas" that I need to be aware of when using iMic with USB in combinations with other USB devices? Like, don't use that type of USB device in this or that port, or there is a Product ID identification problem when using something from Griffin and XYZ?
I'd like to figure out how to use the iMic consistently and reliably.

Virtualbox: usb troubles

I installed virtualbox 4.2.16 and its extension pack to get USB abilities in my guest OS.
Everything was installed correctly: pacman didn't show any errors.
But it didn't work out of the box: I had to create an empty directory /etc/vboxusb
If I didn't, I wasn't able to list my USB devices.

Windows Vista was reinstalled, with all the drivers included in the DVD supplied with the notebook,
downloaded the BIOS update (ver. 1.60), and was installed

T41 USB trouble - nothing works !!

Hey all - bit of an odd one this - im having USB issues, no matter what the usb device I plug into my ports on the T41, it does not get recognised...... however, sometimes I get the usb icon appearing in the corner saying USB device not recognised....yet there is nothing plugged in !! Any ideas as to what the problem could be as its smegging me off having so many things to put on my ipod lol

This is a known problem on T4x units, and amounts to a minor motherboard failure with no known cure. You'll have to buy a PCMCIA USB 2.0 card and feed your stuff from there.
Hope this helps.
Cheers,

USB Troubles

I have an HP that is about a year and half old. Recently it won't recognize USB cords. It doesn't matter what it is. I also tried to use my zip drive in it and I can't use that either. I have tried cords that I know work in other computers and I have used my cord in other computers and it has worked! Is there a way to check to see if the USB is bad on the computer or should I take it in and have someone look at it? I also tried to do it from the back and it won't recognize it. PLEASE HELP!!!

Use self-powered peripherals?

USB-trouble on 7235 P965 Neo board

Hi,
I resently bought a HP Photosmart C4280 all in one printer. However, connecting this to my computer to any USB port causes that the computer completely freezes up.
As soon as the power to the printer is switched on or a switched on printer is connected through the USB port to the computer this happens.
HP-help center advised to change the drivers of the USB ports and choose the Standard USB host controller. Doing this I noticed that only 2 of the 7 USB host controller in the device manager are listed as "enhanced" versions the other are the "universal" versions. I came to understand the enhanced version means USB2.0 and the other USB 1.1. This brings me to my questions
- Is it correct there are only 2 USB2.0 host controllers possible, and how can I find out which usb-port this refers to. I have 4 in the back (on the MoBo) and 2 in the front panel.
- From MB is advertised having 10 USB2.0 ports. No mention of USB1.1 only ports. Is this correct. (I suspect the backpanel USB ports of beiing only USB1.1.
- I cannot install the "enhanced" drivers for the now listed "universal" host controller. Is this correct.
- Does anyone have additional thoughts/ solutions about a printer that freezes up the computer when connected or powerd.
As mentioned in the title my motherboard is of the type MSI P965 Neo version 7235 V1.1.
Thank you for your time.
M.

All of your USB-Ports can operate either in USB 1.0 or USB 2.0 mode. They are assigned to the proper controller when an USB 1.0 or USB 2.0 device is connected. Have a look at the explanation I provided here for comparison:
