How to clear USB Device Information

Hi,
I'm developing USB hardware as operate as HID keyboard,
Some Wrong Informations about USB keyboard device are saved OSX under debug,
that seems to be keyed by USB VID/PID.
Is there way to clear this informations and set as never connected that USB device before?

Does this help?

I think Jong was telling you that your question was very not clear.
(And I agree with him!)
I'm assuming you are talking about the document history available by
command/control clicking on "About InDesign" and/or plugin history.

Hi kimhyun,
I have attempted this.But succeeded.I used pendrive as my USB device.my sugesstion is you don't disconnect your device at any point of your work.Check the device is connected properly.IF your system has recognized your device,you can view the device in control panel>>Device Manager>>Then open your particular device from the list of connected device then Details>>device description>>Hardware Ids>>Then you can find your vendor id there.
Try this.I think your device is loosly connected.Which USB device are you using??Also you must install THE DRIVER OF YOUR USB DEVICE.
GOOD LUCK
Thanks as kudos only

[SOLVED] Openbox+Thunar, how to show usb devices in thunar?

Hi. I've been running a pretty standard Xfce environment for a while. When I plug in a usb drive, I get a new item pop up in the "DEVICES" section of the left panel in thunar (note, it doesn't automount the device, it just shows that it's there and only mounts it when I click on it...I like this behaviour).
Now, I'm setting up an even lighter-weight environment, just openbox and tint2 with thunar as the file manager. But when I'm logged into the openbox environment, I don't get the item in the "DEVICES" section in thunar (but it still works fine in xfce).
If it run thunar from the command line and plug in a usb drive I get this message in the terminal
(thunar:21205): thunar-WARNING **: Failed to launch the volume manager (Failed to execute child process "thunar-volman" (No such file or directory)), make sure you have the "thunar-volman" package installed.
I don't see why I would need thunar-volman if it works fine in xfce. If I install thunar-volman and do the same, I get this message
thunar-volman: Unsupported USB device type.
thunar-volman: Unsupported USB device type.
thunar-volman: Unknown block device type.
So I'm wondering if maybe there is a daemon that is autostarted during an xfce session that makes thunar probe for devices to be plugged in or something like that. Why does it work in an xfce session, but not in an openbox session?

Thanks for your replies.
henk: I tried installing polkit-gnome and creating the rule as per the wiki, but it didn't work. Volume detection seems to work fine in xfce without this package.
jv2112: I added udiskie to .config/openbox/autostart and it seems to work. I've had problems with udiskie in the past; it seemed to have some trouble unmounting the drives properly after a write as I would find that the newly written files were corrupt. But it seems to be working fine.
I'll mark this as solved, but I'm still curious as to how xfce-thunar is mounting the usb devices.
One clue is that with udiskie, devices get mounted to /media, whereas in xfce they get mounted to /var/run/media/username/ (or something like that).

How to detect USB device drives

Hi
I want to write a program which will detect the drive letter when a usb device is plugged in. i.e., if a usb device is plugged in and the drive letter is "F:", then my program will instantly detect the presense of the device as well as get the drive letter. How's that possible in Java?
Thanx in advance
Regards
Mathew

Well if you're looking for the newUSBDriveListener API you're out of luck.
There is no way to do what you are looking for in a number of ways.
1) If something is listed as a drive the best you can now (from FileSystemView) is that it's a drive.
2) There isn't "new drive/or device added" event API.
So what you would have to do is when your program starts get the list of roots. Then poll at some intervals to get the list of roots and see if there are changes. If new drives show up then they show up.I agree!!!

How To Share USB Devices Between Two Mac's?

I am musician and have several USB controllers that I would like to share between my Mac pro and my Macbook Pro. (drum pad, keyboard controller,USB midi interface etc.) I have seen several switches offered on the net, however they all seem to be for PC from what I have found really.
Belkin 7-Port Desktop USB Hub (F4U017) was recommended but the language in the the description does not mirror the same types of functions I am seeing mentioned in units made specifically for the PC. (ie "share USB devices between 2 computers.") Did I taint my mind by looking at the PC items first? Is it really as easy as to plug two Macs into the same USB hub and share their devices? Does anyone have a working solution they are using for this type of situation? How do you do it?
If I could share 7 USB devices between the two systems, I think I would be just this side close to Heaven in ease!
thank you!
Cheers,
Marty

Thank you for the lead Direwolf, it felt like there might be a little more to it than just connecting to a hub. I just converted from PC about 8 months ago. Loving my macs!! A KVM switch I had not thought of that. I will look into. I read the wiki page and it seems like a kvm would replace the screen sharing feature the two machines can now use easy enough, only without using the cpu overhead to do it??? (i think is what I understood)
Does anyone have a model they are using and can recommend? (it's a jungle +out there+) I just did a quick search and found mostly kvm switches with 2-ports USB,. ... looking for seven, come on lucky seven! lol!
I will keep looking. In the mean time if readers have additional ideas, I will be very grateful! Cheers!

How to sleep USB device?

Hello, my 24" Imac gets pretty hot so I bought a little desktop fan that is powered by USB. It works great and keeps the Imac much cooler. However, when I put my computer asleep for the night my new USB fan is still getting power and stays on. Is there a utility I can use to tell it to sleep the USB device? Thanks, Alan

Disconnect the fan or if it has an on/off switch turn it off. The fan obviously has firmware that continues to draw power from the USB port when the computer is asleep. This is a "problem" with the fan, not the computer.

How to clear usb flash drive

Just would like to clear flash drive (usb) so I can use it again. Why does apple make it so hard to do, on my HP the erase message always came up. Please help, Thanks

It's not so hard, but you must adapt to the way of do that on OS X. To erase any disk:
1. Open Disk Utility (in Utilities folder) and choose the disk you want to erase (in your case, the USB drive) in the sidebar.
2. Go to Erase tab, choose the format you want to use with the USB drive and press Erase

How to receive USB device handle from DLL

Hi All,
I'm working on a firmware
running on a development kit and I'm trying to communicate with the
board through USB from Labview in Windows environment. For that, I've
built a DLL which enumerates, opens Read/Write file handle and does a
few other functions. I'm using standard Windows APIs for USB
initialization.
I use "Call libr. function node" in labview to call these dll's. Inside the DLL, I use a function to initialize the USB which returns a device handle to the labview. My question is, in "Call libr. function node" what is the parameter type I should use to receive the device handle? The device/file handle is defined in the WinAPI as a void pointer.
Any help will be much appreciated.
Thanks,
Hari

Hello Hari,
Have you seen this thread? DLL call with HANDLE type

How to clear old devices from My Network list on Verizon Quantum Gateway G1100?

There are a bunch of devices that haven't been on the network for two weeks (when I set up the new router) and won't be on again ever in My Network (http://myfiosgateway.com/#/network). I've blocked them but want to remove them so they aren't in the list. How can I do this?
On http://myfiosgateway.com/#/advanced/dhcp/connections the devices that haven't been on in two weeks are showing as active there, however my work laptop is showing as expired even though it was connected several days ago. I can delete the expired one - all the other old ones are still active.
Confuzzling, especially considering there are 73 days left on the IP address lease of the never-to-be-seen-again devices, while a device that connected for the first time today has 3 hours left.
Solved!
Go to Solution.

Reboot the router and they should be gone.

How to get audio device information connected with MAC system?

I want to know the samplerate (the number of samples per second) supported by the device connected with the MAC system.
I am also pasting the code as below where I need that info.
// Using PCM 44.1 kHz, 16 bit signed,stereo.
          AudioFormat audioFormat = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, //     the audio encoding technique
          44100.0F,// sampleRate           the number of samples per second
          16,      // sampleSizeInBits the number of bits in each sample
          2,       // channels           the number of channels (1 for mono, 2 for stereo, and so on)
          4,       // frameSize           the number of bytes in each frame
          44100.0F,// frameRate          the number of frames per second
          false); // bigEndian          indicates whether the data for a single sample is stored in big-endian byte order (<code>false</code> means little-endian)

Can you sugget something in that area.That's not an issue that's specific to MAC, it'd be specific to any system with a limited number of supported capture formats.
I've handled this problem in the past by generating an array full of all of the AudioFormat objects I'd consider acceptable, and I just iterate through them until I can find a TargetDataline that supports it.
TargetDataLine tdl = null;
/* Write your own code to get an array of acceptable formats here */
AudioFormat formats[] = JavaSoundFormats.getFormatList();
for (AudioFormat format : formats) {

                break;
            catch(LineUnavailableException e) {

Need information on how to comunicate with USB devices

I have an aquisition unit that connects to the computer trhough a USB port. Does anyone knows how to comunicate usb devices with labview using a Universal Serial Bus (USB)?

Sorry for digging up old threads, but it seemed most relevent, and I always figure it's best to add onto old then start new. For ease of the next persons search.
So anywho, My first question is... I assume it is not necessary to open and close VISA sessions to USB ports, right?
I am having an issue where my device doesn't like to work unless a specific series of events take place... very unlike USB Devices in my experience. For instance, if you have the said device plugged in, and you turn it on, then open labview. It will spit out garbage. If you close labview, do nothing else, and open labview up... it will spit out the same garbage. ( by garbage i mean a series of y's with dots over it, and odd looking p's ... you know the kind of letters you get by pressing alt+###... i think in hex it winds up spitting out something like FF EF FF FF FF EF EF ) .... now, if from this current state, I unplug the USB and plug it back into the device, it will finally start to communicate properly.
Im curious why either labview or the computer itself are not recognizing the device on the USB port properly unless it is unplugged and then plugged back in. Ive tried to do reading on USB, and got all sorts of interesting tid bits of somewhat useless information. Im trying to determine if this is something I am not doing in labview, or if this device should have a driver to register with windows, or what exactly the issue is... Just a little background, I do explicitly know all the individual commands to this device so it is not an issue to communicate with it directly through visa...
Thought some of you might have insight or some similar USB experiences....

My start up disk Macintosh HD is full on my McAir OSX 10.9.4 memory 4GB. I need to clear the disk so that I can update it with the new software IOS 10.9.5 requiring 2.05GB. Need guidance on how to clear space.

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then restart the computer. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation—not the mythical 10%, 15%, or any other percentage. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS or GP can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window by pressing command-V. You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Ignore any other messages that appear in the Terminal window.
The application window will open, eventually showing all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with the app, quit it and also quit Terminal.
