Default Sound device with attached USB devices

Hi,
my situation: i've got an iMac 27" with an attached 24" cinema display (using display port and usb). Also i've plugged in a usb headset (headphone with microphone).
Whenever booting up Mac OSX 10.6.4 (also happened to older version of Mac OSX, at least all 10.6.x versions) OSX sets the default audio device (input, output and system sounds) to the cinema displays audio device. No matter what i choose as the default sound device i have to reset it after every boot.
Does anyone know how to come around this? I know i can easily set the device by alt clicking on the speaker symbol in the menu, i know there are tools out there like SoundSource that let me even more easily set the sound device but all i want to have is a default sound device that doesn't get overridden on every boot.
Any help?

All right, I seem to have solved it. The fact that it was only working using plughw: should have tipped me off, but at any rate, this is my working ~/.asoundrc:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
ctl.!default {
type hw
card 1

Premiere Pro CS6 does not recognize USB PnP Sound device connected to iMac OSX even when activated in Audio MIDI setup. The iMac(i-7 processor,16 GB) is working with this USB device without any problem

Premiere Pro CS6 does not recognize the USB PnP Sound device in order to produce a commentary sound track. The USB device has been activated on the iMac OSX by using the Audio-MIDI-setup and is working correctly with the iMac. When opening > presets >audio hardware I can only select between >standard >out integrated > digital input integrated >microphone integrated. USB PnP is not indicated at this place.
With the built-in microphone of the iMac I can produce the commentary sound track, but I would prefer a stand alone version for better quality.
Your help is highly appreciated. Thanks in advance, Annemarie!

I'm using a Logitech Webcam Pro 9000 (which has a microphone on the side). I have several other devices plugged into separate USB slots: a keyboard, a mouse, my iPhone, and a Roland keyboard midi controller.
I've considered that maybe the webcam/mic combo is the culprit. If USB doesn't work at a constant speed, that could very well be causing the issue! The sound begins to lag badly sometimes when it's working properly, so that there's a multisecond delay between speaking and hearing my voice repeated back over the mic which is another sign that something is wrong. I've also caught it making a strange electronic sound during its "hang" time once it stops taking sound input correctly.
Maybe I should try to use line-in and forgo USB altogether then. I think I'd need a preamp and some sort of converter for that since the Mac Mini lacks a powered mic jack. I'm only a newbie musician so I've never set up such a system but it might be a better solution in the long run.
I'll check to see if it hangs before or after my computer enters suspend mode, that's a good suggestion too. Thank you for your help!

USB Device Not Recognized - USB device attached has malfunctioned & Windows does not recognize it

I have an HP Pavilion dv4 Notebook running Windows 7 Home Premium and the USB ports worked fine for an HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB Device Not Recognized" and also indicated that the device attached to the computer has malfunctioned. This prompted me to buy a new Canon digital camera. Well, a new camera did not fix the problem. Now, anything connected to either of the 2 USB ports will not be recognized by my laptop. Help! I'm at a loss to figure this out. I've tried the suggested Microsoft help below:
Suggestion 1: For the issue with USB devices, uninstall and re-install all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition.
The USB controllers represent the USB ports in Device Manager.
a. Click Start, type device manager in the Start search box and hit Enter.
b. Expand Universal Serial Bus controllers.
Note: You might have to scroll down the list to find this item.
c. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
d. Repeat the above step for each USB controller that is listed under Universal Serial Bus controllers.
e. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
f. Check the USB device to see whether it is working.
This did not correct the problem. Then from device manager, I tried updating drivers on all the USB controllers and root hubs. While some may have received downloaded software updates, it still did not correct the USB device not recognized problem after restarting the computer. I'm hoping someone knows of the fix to this situation and can pass it along to me. Thanks for reading and posting any help.

Hey 655micha,
I'm sorry you're having an issue with a USB device. Do you get an error window that pops up? If so what does it say? Have you checked Device Manager? Is is just one device that isn't working? Has it ever worked before? Is it just one USB port in particular that isn't recognizing devices?
What model do you have? Here are the steps to find your product number. FN + ESC is the easiest way to find that information.

Identifying attached USB devices

Is there some way to get a list of attached USB devices and their speed (i.e. USB 1.1, USB 2.0)?
 20" Intel iMac (2.0GB RAM, 500GB HD + 1.5TB external, 20" Cineama Display) Mac OS X (10.4.7) All tools, no talent!

I guess the manuals would if I could find them I'm pretty sure the hubs I've added are all 2.0. In the Window's world, if you plug a USB 1.1 device and USB 2.0 device in the same hub it warns you that the faster device may not work at the faster speed. I've found this to be true. I've been getting some strange results with my USB devices on the iMac so figure it's time to separate the 1.1 and 2.0 devices to different hubs. We shall see.

Unable to attach USB device in XP Mode on Windows 7 enterprise x64

I am using XP Mode on win 7 enterprise edition x64, when i try to attach USB devices on XP Mode i receive the below message
''Could not attach the USB device. You can attach the USB device to the different USB port or restart the virtual machine and try again"
USB devices works fine on windows 7 but not in XP Mode.
Any suggestions please..

Hi,
From what I have known, not all USB devices will work under XP Mode hubs.
Also, Windows 7 XP Mode is not capable of detecting or recognizing USB 3.0 ports on the host system. It is only capable of detecting and recognizing USB 2.0 ports.
Does the USB device can be detected in the host machine? On the host machine, go to Device Manager, check if USB Virtualization is installed, try to uninstall and re-install it for test.
Meanwhile, please refer the following article and check the result:

My Macbook Air behaves strangely with my USB devices.

Hello! My Macbook Air behaves strangely with my USB devices. They appear in the Finder but the icon then quickly disappears, as if the device has never been connected. Sometimes the devices work fine, however. Could you please help me identify the problem?

USB draws power from the MBA, and MBA will shut them down if too much is taken. Try a self-powered (not USB-powered) hub, to see if the AIr acts better. Costs about $25 at BestBuy.
May not tbe the final solution, but no a bad idea anyway.

How to communicate with HID USB device under windows XP with Labview

I have designed a EZ-USB FX2 device and I need to communicate with LabVIEW. I mean I just want to send and receive data. I don’t know how to achieve this goal.Someone have advised me to design a HID device,then use VISA Driver Development Wizards to generate driver(inf file).SO I defined it to a hid device .However when I connect my hid device to the computer, it will automatically be recognized as HID compliance device. I can’t to install the inf file driver. I wondered whether all HID devices will be acquiescently installed the drivers contained in the windows rather than use the inf file driver generated by VISA Driver Development Wizards? If so，what should I do next to communicate with HID USB device under windows XP with Labview? HOPE TO GET HELP!

Hi,
I am working on a project using PIC18F4550 MCU and USB.
I would need to send and receive data from the MCU thru USB. I have uninstaled the HID and created a new NI-VISA driver for my MCU. this worked fine, and it did showed up in MAX
Unfortunately I was not able to receive data from the MCU, Just sending!
I thought to use HID.DLL but the way I need to use the functions inside the HID DLL is simply too much for me, I am not a PC programmer.
There is any kind of VI that is able to use HID.DLL to comunicate with external devices conected to PC thru USB?
Please Help

Problem with detecting USB devices.. something abt ehci-hcd??

Hi All,
I have a DELL E6410 laptop. I have a problem with connecting USB devices.
Whenever a power event (such as connecting/disconnecting of AC adaptor) happens, my laptop stops detecting any USB devices and any changes that happen on the USB ports. That is, say an external mouse is connected to the laptop, the mouse stops functioning, and if I connect a mouse/USB_stick or any such thing to the computer, the device is not detected.
dmesg output show that any connecting/disconnecting events are not detected by the computer. lsusb output too shows the same thing.
To solve the problem, I need to rmmod the module ehci-hcd and modprobe it back. That is, I have to run the commands rmmod ehci-hcd followed by modprobe ehci-hcd. Then, this problem goes away until the next power event happens.
This event does not happen all the time, but it happens very regularly.
Here are the kernel and laptop specs..

Kindly help me on this issue.
Thanks

This is the output of kernel.log when I unplug my AC adaptor with the external USB mouse connected.

Open Default Email Editor with attachment

How I open default email editor with attachment. Now I can just open the email editor with mailto,subject,body BUT i cant open it with a attachment, which is in a server.

So either I could either just create the attachment somewhere and let the customer handle the whole email side of things OR I could make use of the fact that my customers email address is embedded in their license and that an smtp server can be used to send an email from anyone, to open a form for the user to write a problem description and then send it from within my application, but the trouble with this approach is they can't have full control over the email they send.

Hi, How do I communicate CANopen device with anyother CAN device? What things needs to be made compatible with 2 CAN devices to communicate?

Hi,
I have to communicate CANopen device with other CAN device which uses GMLAN.
So in general, How do I communicate CANopen device with anyother CAN device?
What things needs to be made compatible with 2 CAN devices (i.e, one is CANopen and anyother CAN device) to communicate?
Please reply.
Thanks,
Najmu

Hello,
The two devices need to be connected with a CAN cable and while carrying out the communication, one device should be the master and the other should be the slave. Also you should maintain the same protocol (Baud rate, Arbitration ID etc.) at the two devices.

Can't attach USB devices in Windows XP Mode

I am still trying to set up my new Probook G1 450. It is presently in the original Win 7 Pro 64-bit OS.
I am trying to use Windows XP Mode. I can set up XP Mode, but I can't get USB access under it. But for me, the whole point of getting XP Mode is to be able to run two key programs which require USB access. The USB devices have been successfully installed in Win 7 (it's the programs that require XP Mode).
I have tried with VMLiteXPMode, Virtual Box, and finally with Windows Virtual PC. The results are about the same. I am presently trying Windox Virtual PC. When I access the USB button on the top of the XP Mode box, there is a list of all the USB devices. This looks like things are fine. All the devices are there. Hooray. Oops, too soon! It still doesn't work. One still has to "attach" the USB device, by clicking its listing under USB devices. When I do this, I get the following error message:
"Could not attach the USB device. You can attach the USB to a different USB port or restart the virtual machine and try again."
Yes, I can and have done all those things, and I get the same error message again and again and again. This is true for all USB devices (except the USB mouse, which works perfectly and automatically in XP mode and is *not* listed under USB):
* Epson Perfection scanner
* HP Laserject printer
* the computer's own HP HD Webcam,
and
* the computer's own Wireless/Bluetooth Device
For example, the scanner and printer will work well in the host machine, where I have installed them, but they can't be "attached" in XP Mode.
Notes:
* I have enabled "integration features"
* I have tried disconnecting and reconnecting the devices.
* If I try to install the printer in XP Mode, I can't do that, because this requires, at some point, the printer being plugged in to the USB. And I get the above error message when I try to attach it.
Also I have already had to deal with one driver issue (it came with the wrong driver for wireless; the right driver wasn't on the HP support page and couldn't be obtained by the computer's own "update' function), but when I finally discovered the right driver, wireless worked flawlessly
There is yet another possible driver issue, but I'll leave that for another topic later. One thing at a time.

Problems with multiple USB devices. (Possible Low Power on USB Bus)

I believe I'm having an issue with the USB bus or one of my devices that I have installed on my iMac.
I purchased this iMac along with a printer (HP C4280 All-in-One) as part of a promotion deal. I also have wireless logitech USB mouse, and iPhone and an 80gb 5th Gen iPod.
My problem has to do with syncing the iPod and iPhone. Normally I have the printer attached to the iMac along with the USB mouse. Both devices function as expected. However I have problems when I connect the iPhone or iPod.
iPod Symptoms: When I connect the iPod the iPod screen shows the flashing red circle with a line but iTunes never launches and the iPod never syncs.
iPhone Symptoms: When I connect the iPhone the iPhone screen says Sync in Progress and iTunes does show the iPhone in the list of devices but a dialog appears giving me one of two messages (that I've seen so far) - [msg 1] Your iPhone is corrupt please disconnect then reconnect to restore. [msg 2] iPhone device timed out.
I've been dealing with this problem for a couple months and found that if I disconnect the printer (HP C4280) then connected either other device then everything works just fine.
I downloaded XCode 2.5 and launched the USB Prober utility. Then plugged in each device in turn and found some interesting findings.
When connecting the iPhone (1st attempt) the USB Logger reported; (iTunes displayed msg 1 from above)
128.517 [1] USB Device iPhone is violating Section 9.3.5 of the USB Specification -- Error in GetConfigDescriptor( wLength = 4)

1809.166 [1] AppleUSBEHCI[0x28a7000]::Found a transaction which hasn't moved in 5 seconds on bus 253, timing out!
I'm suspicious of the USB Low Power Notice. If this is true then I suspect the my iMac might need some type of repair. However I am also suspicious of USB Device violating the USB Spec Error. Although this is the message that appears when I plug in the iPhone or iPod I don't think I can assume that error relates to the iPod or iPhone. The error doesn't specify which USB Device is in violation.
My current workaround is to unplug the printer every time I sync the iPhone or iPod which is cumbersome. I'm also worried that repeated connecting/disconnecting of USB plug for the printer will over time damage the USB port.
I'm not sure what options I have here. Can anyone provide some suggestions or information that might provide some insight.
Best Regards,
xgnomex

A-Ha! Now I'm feeling like my 1.5 hours of reading this forum are not wasted, since I've found others with similar symptoms.
I've only had my iMac for two weeks today. I've got some new accessories & have experimented with the ones I've had awhile (various USB external drives). My model has 3 USB ports, one of which is taken by the keyboard, of course.
Over the weekend, I picked up an MS Office 2008 Upgrade and also an HP Officejet Pro L7680 all-in-one. I only mention the Office upgrade because I installed it on the same day as the printer, but it's possibly unrelated.
I actually have a Belkin 4-port hub--not the same one suggested in this thread, but externally powered with it's own A/C adapter. (It's a Hi-Speed USB 2.0 r-Port Hub, model F5U234 Rev.3, and I used it with a previous iMac G3 CRT with no problem.)
So with a LaCie 100 GB USB Mobile Drive in one of the iMac's ports, and the HP L7680 in the iMac's third port, or the HP via the Belkin hub in iMacs the third hub, here are some of the symptoms I've seen:
1) while browsing in Firefox, suddenly the mouse-cursor will "freeze" (get stuck) in a pull-down selector...sometimes it unfreezes, but eventually (like on the next pull-down menu) the keyboard & mouse will shut off (and if you wait & the iMac goes to sleep, the keyboard won't let me enter my unlock password when I wake the iMac with the Apple Remote)
2) when trying to open a document from the LaCie in MS Word, Word freezes and the keyboard & mouse go dead--terminal beachball--to restart the computer, I have to hold in the power button
3) when trying to print a message in Mail, Finder freezes (though the print job does finish)
These symptoms seem strange! Hey, it's just supposed to work, right? But everything has limits, so my question becomes, "how much stuff can I hook up at once?"
I wonder if this Apple article is addressing this issue:
http://docs.info.apple.com/article.html?artnum=25243
especially when it says "Two high-bandwidth devices or two isochronous devices cannot be connected to a single Universal Serial Bus (USB)."
So only two hi-speed USB devices can be connected "to the same bus" simultaneously? I'm not entirely sure I understand what "isochronous" means, but I'm thinking I need to peel my printer off the USB somehow, maybe via Airport Express--?
Does anyone know for sure about USB limitations? Thanks.
Also, xgnomex, how/where did you find that "USB Logger"? Is that something iPhone-specific, or is it an OS X log in a Library somewhere?
