USB working, not working, working?

Hello,
i own a 2008 Mac Pro and have some problems with my USB Ports. I tried to find information on the internet but i was not able to solve the problem. I did everything from smc Reset to Parameter Ram Reset, Installing a New System, Reinstalling the Combo Update but nothing worked at long sight.
The trouble is, that some external USB Devices do not work on some of my USB Ports at my MAC Pro. Yesterday for example my original Apple Keyboard which was attached to the USB Hub at my DELL Screen stopped working while other devices still did their work. I plugged off all devices and tried different USB Ports and got the Keyboard to work on another port but afterwards my mouse did not work any more. The same problem occurs with my external WD passport USB Drive, my Iomega REV Drive and any other device. Some USB Ports work, some do not work. Some only work when they want to. The external WD USB drive used to be plugged into the front USB ports, where it worked perfectly until some months ago. I had to use another USB Port to get it to work but it also stopped working with the HDD some time later. Both of the Ports still work with my Ipod or Iphone but not with the HDD or other devices. I also tried to use a powered USB Hub which did not solve the problem on long sight. After setting a brand new leopard system, the WD HDD worked on one of the front usb ports but stopped doing so some time later.
Can anyone help me with this issue? I am really desperate and annoyed ... i do not understand why this expensive machine does not work as it should.
Thanks and best regards,
tm

I have an IMac (intel) and I am having the same problem. Since i updated the bluetooth firmware my bluetooth and usb ports do not work. Any clue?

USB devices not always working

Some USB devices do not work correctly when using the USB2
brackets connected to pins JUSB1 & JUSB3 pins on my k7t266 Pro 2/RU Board.
They always work fine on either of the 2 usb ports located next to the mouse & keyboard. I fear that the "USB controllers" may be incorrect.
How should they be named (and how many times) in the device manager ?

Hi,
Are you using the latest updates and patches?
Are you using WinXP with SP1?

Usb (#3) not longer working?

Regardless of what device I plug into the third usb port, nothing seems to work. I just want to make sure I didn't miss something and maybe disable or turn it off. All other ports are working normal. I'm running Lion and Windows 7 in Boot Camp and the port is inactive in both.
Any suggestions would be appreciated.

1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds. a few minutes.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.

Blue Yeti USB microphone not working in ALSA/PulseAudio

Hi all,
I recently bought a Blue Yeti USB microphone. It is supposed to require no drivers for Windows and OS X, and so far, it works well under Windows, but I cannot seem to get it to function on Arch Linux. As fair warning, although I am relatively experienced with Linux, I don't know much about the internals of ALSA/PA --- up until now, it has just "always worked", so this is my first real foray into the area. I've tried for many days, with no success, to get this thing working.
So, let's start off first with my configuration.
I have a few audio devices:
An on-board audio solution that I don't typically use. For testing, I have connected an old, crappy pair of headphones, but normally I keep this disabled. It has one capture device. (Analog stereo [or 5.1/7.1/etc] duplex)
An external DAC that is connected via USB and is output-only. So, no capture devices on that. (Digital/IEC958 output)
The Blue Yeti itself, which is connected via USB and supports output (it has an internal DAC) as well as input. So, one capture device here. (Digital stereo output and analog stereo input???)
The HDMI-out stuff for nvidia, which I never use
Here is the output of "arecord -l":

If the output of "aplay -L" is needed, let me know, but it's not all that different from arecord -L.
Here is my /etc/asound.conf:

I don't remember where the bulk of that came from; maybe it was installed like that or maybe I put it in there. Here is another useful command showing non-commented-out/non-blank lines in the pulseaudio conf:

Honestly, I think that's about all of the configuration info I can give. Here are some screenshots of pavucontrol, though, in case you are not yet sated: http://imgur.com/a/ngyLl
Now, on to the debugging stuff. First: everything except Blue Yeti recording works. The external DAC works, the on-board audio (both input and output) work, using the DAC in the Blue Yeti to play music/monitor the microphone works (so it works as an output). The only thing that doesn't work is actual recording from the Blue Yeti itself.
When I try to record from the Blue Yeti with parecord -v, I get very strange behavior. Essentially, the "latency" of the microphone measured is exactly the same as the time it has been recording. That is, if it has been recording for 5 sec, then the latency is 5000000 usec. Also, if I try to record something in Audacity, I get no result except for a message box that says "Latency Correction has caused the recorded audio to be hidden before zero. Audacity has brought it back to start at zero." Also, pavucontrol doesn't show an input volume bar for the Blue Yeti, as in the above screenshots, whereas it normally will for microphones that are getting input. The Yeti is not muted, either, so it should be picking up ambient fan noise and such.
Does anyone have any ideas? Is there some configuration error I've made? Typically, this sort of stuff simply works out of the box for me, so I am somewhat stuck on what to do. Could it be a driver-level bug?

I'm not sure what you mean by "mixed with audio in Alsamixer". Can you clarify?
With that said, my problem did mysteriously fix itself after some update (presumably to alsa). Unfortunately, I noticed it in passing one day while I was changing the volume of something in pavucontrol, so I don't remember the exact update that caused it to work. But yes, my current setup does work now: I can listen to audio through my DAC and use the Yeti for recording. However, I have found that use of the Yeti crashes Google Hangouts, although it works perfectly in every other program I've tried.
As documentation, here is my current working setup (it is very similar to the above): in PulseAudio, the DAC is set to be a Digital Stereo (IEC958) output. The Yeti (called an 'Integrated Rate Matching Hub' in pavucontrol) is set to be an Analog Stereo Input. In the input devices section, I have the Yeti's volume set to around 58% (-14.31 dB), which is past the base volume a fair ways but produces decent levels for recording. The DAC's volume is set to 100% (0dB gain, the DAC takes care of the level). In alsamixer, I have the mic level for the Yeti set to 40.
Edit: This is a long-time-later edit, but let me say that when you have multiple USB audio devices, what USB hub and in what order they are connected seems to matter a great deal. If you can't get your Blue Yeti to work, try moving it to a different set of USB ports (controlled by a different controller) on your motherboard. This magically fixes the issue for me.

Ipod "usb device not recognised" on one computer but works with another!

I have a 60GB ipod video and a 2GB ipod nano. Both connect fine to itunes on my work laptop but will not connect to my home laptop. They have previously worked fine with the home laptop but now when conected the message "usb device not recognised one of the usb devices connected to the computrt has malfunctioned". I have tried reinstalling itunes several times and tried the usual reset of the ipods etc but nothing seems to work.

If you have more then one USB port, try the other port.

USB Device Not Recognized when direct to computer, works through hub

I have a rather bizarre problem (which I've already written about on Tom's Hardware) regarding my Samsung Galaxy S III phone and my ThinkPad T440p. At first I thought it was just a driver issue, but now it seems to be more hardware-related.
As I explained in my other post, the phone works (in both Windows 7 and Linux) when plugged in through a USB hub, but not when connected directly to the computer. My computer is still under warranty (thank goodness), but I'd like to avoid sending it in if possible, as it's my only computer.
Any suggestions? Thanks!

I just tried plugging another Samsung phone in with my USB cable and it has the same problem. If I plug it in with another cable though, it works. I use the same cable with my phone and nothing happens. No charging, nothing. At least with my "bad" cable it charges and the computer complains about it.
At this point I'll get another "Samsung USB cable" (supposed to work, eh?) and see what my luck is. This cable is less than a year old though. I already replaced the original. Maybe Samsung went too cheap again... It wouldn't be the first time. Their push buttons fail left and right.

I got a stand for the notebook at www.raindesigninc.com the mstand and I got the $50 aluminum usb keyboard apple sells.
I installed windows xp on a 50 gb partition, put the bootcamp in got all the drivers installed.
Then I got to the office today plugged in my apple keyboard and it was not recognized. I didn't have the bootcamp cds with me at the office.
Are the drivers for the aluminum apple usb keyboard on the bootcamp cd?
I've done some searching on google, and the only solution that i've read is downloading a new version of bootcamp then using a program called transmack to pull the driver out of the bootcamp image file. I hope there is a simpler soution that won't take up so much time.
So do I need to put bootdisk in again to get the drivers for this usb keyboard? Or how can I get this to work as it is now the usb keyboard doesn't work. I had to take the laptop off of the mstand and use its own keypad.

found out i just needed to put in the cd that came with the mac book pro

L550/010 USB port not working properly, non-standard USB ports

I wondering if anyone can shed some light on this strange problem I'm having with my laptop USB ports.
Background.
I have a USB device (CED-M2 USB Chronograph). The device comes with Windows 7 software to upload fps readings.
The CED has a calculator style keyboard - so you can lookup data without the laptop.
My L550 PSLWSA-01000Q, is running Windows 7 professional.
Problem.
When I connect the CED into the USB port the buttons on the CED no longer operate, As soon as the USB lead is disconnected the buttons work. Uploading the data doesn't work either. The buttons freeze occurs as soon as I plug into a powered USB port (even if user not logged into Windows and programs are not running).
I've installed the upload program onto two PC's at home (Vista Home and Windows 7 Home) and both PC's connect to the CED and upload fine. Furthermore, the CED push buttons works perfectly! So, this leads me to think that the hardware or signals from the laptop USB ports is not standard.
I've tried all three laptop ports (e-Sata/USB and normal USB ports), same problem.
Any ideas what could be causing this problem?

Hi Jerry
Firstly, thanks for repsonding.
All L550/010 USB ports appear to work well on other devices (Sierra Wirless card, HP optical mouse, HTC phone), doesn't matter which port (USB, Esata/USB) all works fine with these units.
I've tried connecting the Chrono via a USB 4 port expander - same problem, no comms, chrono buttons locks up. Connect to Home PC running Vista Home and Windows 7 Home and works fine 9 - just can't take those to the range.
The Chrono unit is self powered (9V Alkaline) and it's new, so USB supplied 5V is not a problem.
The buttons seize whenever the laptop is powered up. Also, if the chono unit is powered down, connecting the USB lead to the laptop turns it on (wakes up). This wake up functions on both home desktop PC's and laptop (good), however, with the laptop I can't power down the Chrono as the buttons don't work.
Whilst laptop connected, and rebooting the Laptop, the Chrono buttons will work just before the Press F2 for setup screen comes up - so could it be electrical.
I've downloaded the latest BIOS from Toshiba and Intel chipset too - no change.
I got the unit to connect once tonight - when I plugged my mouse in at the same time - USB configured for mouse, and whilst doing that the Chrono worked. Once mouse working, Chrono stopped. Can't repeat results.

Hi, I have an HP Pavilion G6-2146sl with Windows 7 Ultimate x64... my problem is that the two left USB ports stopped to work properly: for example, when I insert an USB flash drive it turns on but it's not recognized by Windows. The only port wich works is the one on the right of the laptop. I've tried to do a driver search, but Windows doesn't find any driver. Here's a screen of my Windows device management:

Usb ports not working- Hp Pavillion dv6

1. Product Name and Number
    Hp Pavillion dv6-6124ca
2. Operating System installed (if applicable)
     •Windows 7 64 bit/Ubuntu 12.04.1
3. Error message (if any)
     • Usb device not recognized
4. Any changes made to your system before the issue occurred
     • Nothing really. Stopped working while working on an assignment for school
Description:
My usb ports are not working. There is power running to them(light on usb stick light up) however when I plug anything in it says usb device not recognized.
I have tried:
Updating bios(No option in bios to turn usb on/off)
Reinstalling all drivers for usb(removed and restarted so they would automatically reinstall.)
Unplugging laptop and removing battery for a long period of time(all night)
The problem persists in Ubuntu and Windows 7. I am coming to the conclusion that the ports are toast and I will need to replace the mother board. If thats the case can anyone tell me the approximate cost of replacing the motherboard?(If too much ill just be buying a new computer)
Thanks.

Windows 7 (Ent) Sp1 on server 2012 R2 HyperV, RFX USB redirection not working

Hello,
I currently have windows server 2012 R2 with HyperV installed. I have built two virtual machines. A windows 8.1 and Windows 7 sp1. Both are enterprise editions
For RemoteFX the hypervisor is using a Zotec GTX 760 GPU. It recognizes it and uses it to apply remoteFX adapter on my Windows 7 Sp1 VM.
As you are aware I do not need to use a GPU to enable RFX on my Windows 8.1 it can do this without the need of a GPU.
Using an RDP client( v8.1) I can connect to my Windows 8.1 VM with a USB headset,memory Key or a printer and they all enumerate on the Virtual machine. The driver for each device installs
and I can use the device without any issues.
However this issue lies with the Windows 7 SP1 VM. I can connect to it via RDP( Same client) but I cannot redirect any devices to it. I have installed the latest integration services available on the VM. I have ran all updates available.
Because I have ran all updates the rdp version on the VM is running v8.1.
Previous to installing the updates USBr still was not working
I have enabled the following group polices under remote desktop services on the Windows 7 SP1 VM :
RDP 8.0 -- Enabled
Configure RFX -- Enabled
Is there a known issue with USB redirection not working on a Windows 7sp1 virtual machine hosted on server 2012 Hypervisor ??
Many Thanks
Brian

Hi,
According to the log above, I found that we run the script on both Server6 and Server7. Errors as below:
Server6: Conversion is not supported in restricted language mode or a Data section.
Server7: Couldn't figure out valid servers from the specified destination scope. Check your parameters and try again.
Since we can only run the RollAlternateserviceAccountPassword.ps1 Script on CAS server, the script not works well if Server6 is MBX server.
For Server7, based on the error message, it seems you still have no right to run the script/cmdlet.
Please add your account to Organization Management Role group(ADUC->domain.com->Microsoft Exchange Security Groups) to test if possible.
By the way, from Technet:
You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Client Access Security" entry in the Client Access Permissions topic.

Dual-Boot; Restart and boot other o/s USB devices not working

I have issue with my msi z97-g43 mobo and Windows dual o/s PC.
Booting with win-8.1, USB devices working very well.Restaring windows 8.1 have NOT any issue.
After shutdown & start PC, choosing to boot windows 7 on bootmanager, USB devices not working in Win-7.
System no hang or occur any error/BSOD message.All startup programs run as normal.
I tried to re-plug usb devices but notting happens... Still not working
But after the win-8.1 shutdown, if i switch off PSU power button, watting ~1 munute for discharge.
After power up PC and boot with windows 7 all usb devices works normaly.
I checked all internal connections. 2 times disassembly all hardware and re-built system, nothing changed.All windows updates and latest drivers installed.
I'm sure other H/W is OK, but I thnik this mobo have a fault.

Thank you for reply.My PC system specs:
CPU:    Intel Pentium G3258 3.2ghz
Board:    MSI Z97-G43 /Bios: Ver. V17.7
MEM:    G.Skill Ripjaws 2x4gb DDR3-1600mhz cl9 1.5v F3-12800CL9-4GBRL

All hdd's have MBR based partition table.Windows 7 & 8.1 installed in non-efi mode.In BIOS Boot sequence is setting up to non-efi Boot(system) drive as primary.
Before I suspect maybe have a short circuit to pcb or similar thing cause this issue.I take out all parts outside the chassis, and ran this system on the antistatic bag and box.Nothing has been changed.
I have Cooler Master Devastator(MB24 + MS2k) USB keyb+mouse set and tplink wn722n usb wireless dongle.
I have one more pc,based on AMD 970+SB950 chipset mainboard and AMD CPU.I exchange all parts to this amd mainbaord and tested for faulted hardware.All intel system H/W's is ok.All works great
Dual boot works perfectly.Not needs to switch off psu/power back and run system again.
I think msi z97-g43 mainbıoard have a problem.

USB working, not working, working?
