Bluetooth USB dongle stopped working

I have an unbranded USB bluetooth dongle. I'm running osx 10.4.11 on a G4 Dual Optical.
The dongle worked fine, plug and play and I have used it to Sync my Sony Ericsson mobile using iSync.
I do not leave it plugged in as I use it on my work PC too. The dongle is operational as I have tested it on the PC.
Now whenever I try any bluetooth operation including opening my Bluetooth System Perferences the operation fails and I have to force quit System Preferences.
Any advice welcome, thanks

Thanks for this, I thought it was going to work straight off, as it got me into the preferences but it wasn't long before I was locked again. I went to Disc Utilities and repared permissions, then did the process of removing the com.apple.bluetooth.plist file again. After this all seemed to work and phone and Mac are now sucessfully synced once more.

Bluetooth USB Dongle stops working after reboot of 10.5.3

Hi,
I have been using my Mac Pro 2.66 with a USB Bluetooth dongle "Sitecom CN-521" and Apple's wireless keyboard (white one) and Mighty Mouse wireless.
All worked very fine together.
Then suddenly after rebooting 10.5.3, bluetooth is not available.
I first thought that the dongle was dead.
To find out, I tried the dongle on a PowerMac G4 733: it worked perfectly.
Then I thought it might be a hardware problem with the Mac Pro. To be sure, I installed the Vista drivers of the USB dongle on my Mac Pro (through VMware Fusion). It was recognized by Vista. I could even use my wireless keyboard in Vista, thanks to the dongle. But on 10.5.3, bluetooth was still dead and I could not use the keyboard.
It was a strange feeling to use my wireless keyboard on my Mac Pro, only in Vista and not in Leopard!!!!
So it is not a hardware problem (either dongle or Mac Pro). It is a software problem with 10.5.3.
I tried to reboot while unplugging all usb devices and then replugging them after startup is over: no improvement.
So basically, I think of 2 options:
1. either it is a 10.5.3 software problem.
2. either a clean install on my HD could clear this problem.
Does anyone of you has the same problem?
Any solutions?
Thanks in advance.

I answered this question on my own. I was able to utilize Pacifist and reinstalling the video card drivers and display profiles. Now everything works as it should.

3g usb dongle stopped working

Hi I have ZTE MF 195 3g usb modem which was working until couple days a go.
Now refuses to connect, sometimes I got KDE window with login details, and that is all.
I have checked connection details , it is correct, also sim card works in another modem but after 2 or 3 failed connects.
On win$ everything is fine.
Modem and sim card from another provider work well.
I use kde, network manager and standard kernel.
Also noticed this error
(ttyACM0): device state change: ip-config -> failed (reason 'ip-config-unavailable'
Any ideas welcome.
Thank you.

Yes I did upgrade, but strange is that other usb dongles work.
I read wiki but find nothing, also this is 3g dongle, no wifi.
I guess it is not a hardware problem, as that dongle works on win with no problem.
Thank you anyway.
Edit: Just run pacman -Syu I see that usb_modeswitch is on update list. I will report back tomorrow when I test modem.
Don't be surprised that other dongles work and one does not. The bug could affect one chipset and not the others.
I feel for you because I have a unlucky history of wifi problems getting broadcom, now even Atheros chipsets to work. Did you consider a 3g based wifi hotspot instead of a dongle?

Bluetooth Dongle Stopped Working - Now Keyboard Won't Pair With New Dongles

Hi All,
If anyone can shed some light on this I would be massively grateful.
I've been using an old dlink usb bluetooth adapter with my 2007 8 core Mac Pro running OS X 10.6.2. This had been working with my old style bluetooth mac keyboard (the white one with the number panel).
Recently the dongle stopped working (the lights went out and it wouldn't come back to life). I've bought 2 new dongles (HK-760 USB 2.0 & Belkin Mini Bluetooth Adapter) and neither of these seem to connect to the keyboard in Bluetooth Setup Assistant. I get this message: 'The pairing attempt was unsuccesful. This configuraton of Mac OS X and Bluetooth software could be invalid or unsupported.'
I took the keyboard to the Mac Store and it connected to an iMac there, so figure it's not the keyboard.
Any help would be greatly appreciated.
Thanks in advance.

Update: I tried to link the keyboard to my old G3 which it used to work with no problems an it took ages to link up and then on restart wouldn't link up. I'm thinking it might be a faulty old keyboard that died of a broken heart when the bluetooth dongle passed away. Poor thing

Bluetooth USB Dongle does not work

I have this generic looking USB dongle (forgot the brand) that I use with my eMachines e725 laptop. It worked fine with Linux Mint 9 KDE 64bit that I had to use for the past 1.5 years. The moment I plugged the dongle in, it was instantly detected and the bluetooth icon turned active in the system tray. However it does not work with my ArchLinux 64bit install with KDE4.6 (updated to latest packages). Due to issues with the new Kernel 2.6.39 series, I am using the LTS kernel.

I've installed bluez and bluedevil. In KDE System Settings, when I go to the bluetooth options, it says no bluetooth adapters have been found.

Have you read the Bluetooth wiki page?
Seems to me you didn't run the relevant daemon.
Also, your thread title should include 'bluetooth' - 'USB dongle' on its own is too generic.

Satellite A205: Bluetooth USB dongle will no longer connect to AirCable

I plugged a generic Bluetooth USB dongle into my Satellite A205 and used it for several hours over three days to connect to an AirCable Serial Bluetooth to run my telescope controller. The generic dongle worked after downloading a Toshiba stack.
Each time I restarted the Bluetooth it incremented the COM port numbers.
My telescope controller will not recognize COMs above 20 so I deleted COMs that really were not used.
The Bluetooth USB dongle will no longer connect to the AirCable Serial Bluetooth. *It worked before and will not work today.*
I've tried three different Bluetooth USB dongles including TrendNet, AirCable and the generic.
I cannot connect to the telescope controller's AirCable Serial Bluetooth with any of the dongles.
_*Can anyone suggest a Bluetooth monitor that will work, or suggest a way to get my A205 to work with one of my Bluetooth USB dongles?*_

I have Vista. I did not download SP1. It did not appear in the Update Manager. My laptop is about 3 months old so I did not want to download the 400+ MB SP1 to a fairly new version of Vista Home Premium.
Here are steps that did work for me. This process is tedious but it worked three times in a row with no failures after scores of failed connection attempts.
*_Getting Bluetooth to Work With Vista and Generic Bluetooth Dongle_*
1. Power up Bluetooth serial (AirCable).
2. Start laptop with Vista Home Premium and wait 2 minutes.
3. Plug in the generic Bluetooth dongle.
4. Click tray Bluetooth icon to show Bluetooth devices.
5. Select and remove the existing device.
6. Unplug and plug in the generic Bluetooth dongle. My Bluetooth COM Port is 6-Outgoing Serial, and 7-Incoming
7. Add a new connection for the Bluetooth serial.
8. Start; Control Panel; Device Manager
9. If COM ports with a higher number than your selected ports (mine are COM 6 and COM 7) exist, do the following:
- Right-click the port number that is the Output port (Click the Bluetooth icon in the tray to determine which COM number is output and which is input).
- Let's say for my example that Device Manager Ports shows COM 11 and COM 12, and that COM 11 is output.
- Right-click COM 11 and select Properties
- Click the Port Settings tab and the Advanced button
- Click the Com Port number dropdown list and reassign it to COM 6 (the desired Outgoing COM port).
- Click OK a couple of times.
- Now, right-click COM 12 (input), Properties, Port Settings tab, and Advanced button.
- Reassign COM 12 to COM 10 (OK...), reassign to COM 9 (OK...), reassign to COM 8 (OK...), reassign to COM 7 (OK...). (You are clearing out unused COM ports 10, 9, and 8.)
- Click OK a couple of times.
- Click the tray Bluetooth icon and remove the existing device.
- Pull the Bluetooth USB dongle out of the computer and reinsert it.
- Click the tray Bluetooth icon, search for and add your Bluetooth serial device.
At this point your remote Bluetooth device should have a good connection.
+++++++++++++
Thank you everyone for your input. It is too bad that it is so difficult to use a Bluetooth dongle with Vista but such is life.

USB Ethernet stop working after hotplug

I have found that my Apple USB Ethernet dongle stop working if I plug in another USB device. This happens both using a USB hub, and when plugging directly into the MacBook Air. I also see this problem when using a similar dongle from another supplier (called AX88x72A). The USB Ethernet dongle works fine after booting, with status "Connected", but if I plug in another device like my phone or a USB drive, the status changes to "Cable Unplugged" after a few seconds, ifconfig no longer show the en1 interface, and syslog gives a few error lines such as:
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: Ethernet \[AppleUSBEthernet\]: Link down on en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
After this, I must reboot the MacBook Air to get the dongle working again. Do anybody know how to force the AppleUSBEthernet driver to rescan the device tree (or something similar)?
With regards,
Birger Retterstøl Olaisen

I have exactly the same problem here (MacBook Air 2,1 - OSX 10.6.8). After several tries (and reboots!), I've found that an unload/reload of the USB Ethernet driver works.
Note that operation is not automatic: I have to execute commands in a terminal in order to retrieve my Ethernet connection... but it is far better than a reboot!
So, if you want to test my method, once you have plugged a USB key (or after an hotplug of your USB-ethernet dongle), you can execute these commands on your terminal (note there are 2 lines and no space in the kext name, a space may be inserted by this forum):
sudo kextunload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
Of course, i've made a small script with these commands, and copied it on my PATH so it is even easier to execute it. It works perfectly for me, and I hope it could help.

HP Pavilion dv6 All 4 USB ports stopped working

Hello,
I recently bought a Pavilion dv6-6c11sa laptop. Windows 7 Home Premium 64-bit
Everything was working fine for about a week, and then yesterday all of the USB ports stopped working. I have 4 USB ports in total, two 2.0 and two 3.0. No matter what peripheral device I plug in, mouse or flash drive etc, they're not recognized by the laptop. The lights don't even light up on the devices, regardless of the port. I've tried uninstalling and reinstalling the drivers in device manager, taking out the battery and rebooting, installing the chipset drivers (AMD), nothing works. No programs had been installed 3 days prior to the occurence, although I had rebooted several times in that time frame. I simply booted up the laptop yesterday, and nothing worked.
Could anyone offer a solution or suggestion, please?

USB Ethernet stop working after 10.7.5 update

After updated to 10.7.5, my usb ethernet stop working, and always shows it doesn't connect.
Reinstall 10.7.5 make no difference.
How do I solve it?
Thanks!

Or download it directly from ASIX Electronics instead of driversworld.us.

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. WHen we plugged it into the port on the keyboard, the device works. Why?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?

It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

USB Video stopped working with 3.1.8 update

I have been using iChat video with my USB camera for a while with the help of iChatUSBCam. The new update of iChat (3.1.8) included support for USB cameras and once installed my USB camera stopped working with iChat. It just reports the camera is in use by another application. I've been browsing for answers for a while and have tried many things:
- Restart in various combinations of unplugging and plugging in the camera
- Reinstalled the Macam driver
- Reinstalled Quicktime
- Uninstalled iChatUSBCam (since iChat is supposed to work without it now - I think...)
- Reinstalled iChatUSBCam (v 2.2.1 - current)
It's a Logitech Quickcam for Notebooks Deluxe. It continues to work fine with Skype and the the Macam camera tool. I'm using Skype for now (on tour for 6 weeks and use it to video call home) but the quality is crap compared to what iChat used to do.
Thanks for any help you can give.

Some people have reported that Updating iChatUSBCam
and deleting the Macam drivers and then the
com.apple.ichat.plist is the way to go.
Thanks for your help!! I tried these things before, but tried them again in the order you suggested with no success. I'm pretty sure it is not a UVC compliant camera. It's not on Logitech's list of UVC cameras.

If I try it without the Macam drivers it doesn't show up as a camera is connected at all.
It's so frustrating because it was working great with iChatUSBCam until the recent update. It still works in Skype with no problems, but I'd rather be using iChat if I can - much better video quality.
Thanks for any suggestions!

BlueTooth USB dongle problem

Hello,
I have a problem with my BlueTooth USB dongle
OS: Win98
Drivers: latest 1.4.2.10
When I setup a connection the following error occurs:
ERROR: Unable to start the BlueTooth stack service
Can anyone tell me how to solve this problem??
Andries

No configuration or modification of system files is required. If the USB Bluetooth dongle is Mac compatible, just plug it in and open the Bluetooth system preferences pane.
Not all USB Bluetooth dongles are fully Mac compatible.

Bluetooth usb dongle support

hi i am new to forum and java
I am going to buy bluetooth usb dongle .I want to know that by having 2 dongles can I run my java socket programs to transfer data's or files between two PC's .is there anything like java supported bluetooth usb dongle is there.If anyone knows the solution please reply me as soon as possible.

Hi,
One idea, you can set up a LAN between two PC with the bluetooth dongles then easily make them communicate by sockets, or http, or ppp with java or other programming languages.

My USB webcam stopped working after I upgraded to OS X 10.6.8

When I installed the upgrade to OS X 10.6.8 my USB webcam stopped working.
Any idea how to get it back.

Upgraded from what to 10.6.8?
Did it work before?
What camera?

After updating to OS X Mavericks, internet USB dongles topped working. Many other users have faced the same problems.

After updating to OS X Mavericks, internet USB dongles topped working. Many other users have faced the same problems. Can someone please help me out? I am unable to find online help.

Sourcing Drivers for dongles when upgrading OS is a nightmare whether its osx or windoze. It takes the likes of Huawei ages to produce new versions. I strongly recommend getting a portable wifi (mifi) which will work with any device and sits in your pocket not sticking out the usb port where it gets broken. Recommend Huawei E5756
