USB devices no longer connected

Since installing Snow Leopard I have had problems with my Epson R2880 printer. I downloaded a later driver and this worked for a few days but now it will no longer print from any application. My TomTom has also stopped working on USB.
The USB ports seem to be faulty, although the keyboard and mouse are OK, everything else fails to connect via USB. They all show up in System Profiler with correct devices attached but are not seen by the OS any more.
I have tried a reset of the PRAM and also disconnected everything and powered off for at least 2 hours.
Anyone familiar with this problem or have a fix?

I do have a powered USB hub but even direct connects stopped working. I have fixed the printer problem now after a number of attempts. I installed the new 10.6.1 patch for SL but this made no difference. I have now re-installed both Rosetta and the Printer Support from the install CD, both of these are optional but clearly very important.
Finally I downloaded again the latest Epson print driver and my printer is now responding. Unfortunately the TomTom still will not connect so I may try reloading that software too.

I have recently upgraded my iBookG4 from Tiger to Leopard 10.5.8 and find my Bluetooth USB adaptor no longer connects. The Bluetooth pane says inactive. Does Leopard require USB 2.0. I've had the adaptor for some time so may be USB 1.0

Bluetooth icon on menu bar shows bluetooth off. When opening bluetooth preferences it shows the devices I've connected previously,( my mobile phone), and other devices I've attempted to connect but not very successfully: my iPhone and MiniMac. The bluetooth dongle in the USB port shows a continual blue light but does not react and the iBook does not recognise that it is there. There is absolutely no reaction when I try to pair my mobile phone, which I've done successfully before upgrading to Leopard, either by the iBook or the mobile phone.
I assumed that Tiger was not bluetooth compatible with the iPhone or MacMini running SnowLeopard and hoped by upgrading to Leopard I could achieve some file transfers between the three devices (iBook, iPhone and MacMini)

Hi All, I am facing an issue with a 6681 phone while connecting via Cable to my PC. My configuration given below:
OS: Windows XP
Device: Nokia 6681
Connection method: Data Cable
PC Suite Version: Came with the mobile
Problem:
1. It was working fine for a month. But now, I am getting the following balloon message: "The USB Device you have connected has malfunctioned and Windows does not recognise it".
2. Strange thing is, it is working fine with my office machine, having Win XP.
3. I am able to connect my camera to my home PC, so it is not a hardware issue.
4. Tried uninstalling and reinstalled again, no change, getting the same error message: "The USB Device you have connected has malfunctioned and Windows does not recognise it.".
Someone please help.
Thanks,
Sunil.

Hi teurastaja,
Thank you for your response. I tried the same, but again getting the same message. It started detecting the device, then tried to install the drivers, finally it is saying, "An error occured while installing drivers. Your USB device may not be properly". After that, I am getting the previous message continously in the tray with the header "USB device not recognized". Also, I am getting the cable connection icon in the phone screen just for 2-3 seconds. After that it is diappearing. Can you suggest any solution?
Thanks,
Sunil.

USB device keeps disconnecting/connecting after upgrading to Windows 8.1

I have a device(Pedal for Sim Racing) connected via USB, everything is working fine in Windows 7 and 8 but after upgrading my machine to Windows 8.1 the device keeps disconnecting and connecting for like every 2 seconds. But after I open the Property Sheet
in Game Controllers panel the disconnection issue was gone, if I reconnect the device the issue persist. Other people who have similar device also encounters the same issue after upgrading to windows 8.1. The issue persist with or without the device driver
installed.
Any idea, what might cause this?
Best regards
mark

I'v got this exact same problem with my Win 7 desktop. I've also got pedals and wheel but don't see it as different than all the other USB devices. I'm using a bunch of USB, but no hubs, including 3 external storage hard drives. But the momentary
disconnect appears in all devices as best as i can see..even my long time trouble free head phones..keyboard..and all. Sometimes the sound goes away and if I unplug and replug them the sound comes back, and other times I have to exit and re enter the
game. I also get video crashes ..maybe not related.IDK..and have to restart all, because I've got three black screens in Eyefinity. For years my system was trouble free and its just slowly started getting worse. I've thought it had to do with system "sleep"
etc but long ago went to never sleep max performance etc..Makes no difference. Keep thinking its my hardware or my house wiring etc..But can't seem to solve it. I replaced my Mobo/chip/ram maybe 6 months ago and that appears to have not helped. It seems
to be getting worse. I hate to start replacing parts piece by piece..cost a lot of money and sometimes doesn't help.
When I'm playing a game I can often hear "faint" sound of USB connect disconnect happening with regularity..that little bing/boink sound etc..So it must just be constantly happening...Seems weird. Didn't have anything like this happening years
ago with pretty much the same hardware and same Win7 with the continuing updates etc.
What can be causing this common problem?

How to disconnect a USB device that auto-connects to my iMac

I have a third-party device that gathers medical data that can be uploaded to my computer via USB. Now, however, I want to upload it to a web-based application application that runs only on Windows. I run Windows 7 on a virtual machine via Parallels 7. The problem is that when I plug the medical monitoring device into the USB port it automatically connects to the Mac, and I cannot see it from the Windows desktop. Plugging it in no longer gives me the option of connecting to the Mac or the PC. (I think I did an "Alt [right click]" the first time I connected via the USB cable.) So, how can I now force that auto-connect to disconnect? Thanks.

Hi Bob, I remember doing something like that...
On the Mac side eject it without removing it, then on the Win/Parallels side look for that USB thing setting/add device or whatever.

USB device no longer recognised

I have a GoPro which was working fine on the Apple, I connected it to my sons Windows computer to edit some video, now when I plug it in to the apple it is not showing anywhere! Likewise the external hard drive I used on his computer to transfer the files is no longer recognised on the Apple.
I must be missing something? They are still there showing on the Windows computer.

Devices no longer connect to my Hub

We've had our hub for about three years now and have a lot of devices connected to it; an iPhone 5, a iPhone 4, two iPods, a BlackBerry, a Windows phone, a Laptop, a Tablet, a Playstation 3 all through Wireless and a LG Smart TV, BT Vision Box and a Seagate Hard Drive through Ethernet cables. Everything normally works fine.
Last week following an electrical storm several devices could no longer connect to the Hub - the iPhone 5, the Tablet and one of the iPods.
The Laptop is fine and works all over the house as it always does, however, if I use the shortcut on the desktop on the Laptop to get to the Seagate hard drive - I get the message that windows can no longer find it.
My iPhone 5 cannot connect to the Hub - it can see it - but cannot connect to it. I have to drop it a connect to my own Hub through BT Fon and then it works fine!
I've asked my iPhone and the other devices which can no longer connect to the Hub to forget the hub and to get them to search for it again. They can all see it, but can't connect - not getting as far as asking for the wireless key.
I've powered off the Hub and left it for a couple of minutes. I've tried re-setting it and I've been into the Hub Manager to see if it looks like any changes have been made to it. Nothing seems to work.
I haven't changed the channel on the Hub as it doesn't appear to be a signal strength issue (the iPhone 5 shows the Hub on maximum strength everywhere in the house).
Can anyone help please????

Hi Guys,
I've done a factory reset on the huband it doesn't seemed to have changed anything. My iPhone 5 still can't connect to it, I can't use the shortcut for the Seagate drive and the Hub no longer apppears as part of our home network when I look it up on my PC.
Below is a screen shot of the Hub Manager. Matt-PC is my laptop which is connected to the Hub via Wi-Fi. There are currently three Ethernet Cables plugged into the back of the Hub - the Seagate Drive, the TV and a BT Vision box.
Any other ideas?

[SOLVED] USB Devices No Longer Designated by UUID

My USB devices (external disks, flashdrives, etc) have always been mounted using their UUID. I have grsync processes set up using this method which I have used for years. Suddenly, my devices are being shown by label (/dev/sdb1, etc), and now no processes using the UUIDs will work without being changed to use the label.
As far as I know, I haven't done anything, so I guess an update has caused this, but I have no idea exactly when it happened, or how to get back to UUID identifiers.
I would be very grateful for any advice on how to begin to resolve this.
Many thanks in advance.

Berbae, your post gave me a clue where to start, and I have now identified the problem.
I am using Openbox, and had added "spacefm -desktop" to the autostart folder in order to manage wallpaper, etc. This resulted in it running in the background, and the mounting application it uses by default (pmount?) is not showing UUIDs. I removed this from the autostart folder, and everything was back to normal, so it's a spacefm issue which I need to resolve.
Although I haven't fully fixed the problem yet, I know where it lies, so I am marking this as "solved"
Once again, thank you providing me with a starting point.

USB device no longer works after 10.6.5 patch

After installing the patch for 10.6.5 Thursday, my Belkin N52te no longer works. It has previously worked fine, and the system extension for it was able to see it, but now it says "No device connected". I have tried re-installing the driver, and 75% through the installation I get a message that the xxx.kext file was not installed correctly. I get this each time I attempt to re-install it.
This gamepad has worked flawlessly for me since purchase in spring of '09 prior to this.
Please don't tell me to update the driver, as Belkin's "latest" is Feb 09. I have contacted Belkin, and am waiting for a response.
I found a suggestion of finding the old usb.kext file from the system backup I have on a second drive, and replacing the current one with it. If anyone thinks this will work, could they give me the exact name of the file to look for?
It seems odd that Apple, after trying to get the Mac accepted as a viable gaming machine, should put out a patch that breaks one of the most widely used "speedpads" on the market. I have been an avid World of Warcraft player for close to 6 years now. The enjoyment I receive while playing WoW has been the driving reason for me to purchase 2 top of the line Mac Pro's in the past 4 years. Come on Apple, fix this, please!?
Thanks,
Dan K.

February 2009? Snow Leopard wasn't even out yet. It is lucky it has worked for a year and a half.

While this may work, that's a jalopy of a solution. It might break in the next update, not being up to date itself, and some other extension might be dependent on it. Best to downgrade until you can get assurance that it will work with 10.6.5, if this is an important feature for you. You can either recover your backup, or if not available, see this tip:

USB Device no longer recognized (Ratoc U2SCXU SCSI Converter)

I'm having problems with a device that used to work fine in an older MacOS (10.5, Leopard) but no longer being recognized in Lion. The Ratoc Systems International SCSI COnverter model U2SCXU is no longer visible in System Information, their Utility, nor the scanning software (VueScan). This set up used to work seamlessly in previous OS's.
The Ratoc device is being powered through the SCSI connection and lights the power light no problem. No matter wherther through a hub or direct, the USB is no recognized nor is the software. I tried to email the manufacturer but in the meantime thought to post this as a question while waiting... Does anyone have a similar problem?
Using with a Polaroid SprintScan4000 negative scanner. This device and the converter were all running and playing happily in OS X 10.5. There seems to be nothing I can do to make the device appear in the window, nor be recognized in software. Also tried with laptop running the same OS. I believe this is a software issue with the OS. There is a firmware update that might be able to be applied via the Utility software (U2SCXU_50) from Ratoc website, except that the Utility doesn't see this unit either.

Make sure it's the right series usb 3 driver, series 7 or series 8. Series 7 drivers are version 1.x and series 8 are version 2.x. They use the same device id's.

USB Devices No longer working afte 10.4 update.

My external USB 2 drive is now no longer recognized by my Macs after the upgrade. The weird thing is that if I run Parrallels they appear as normal.
The drive does not appear in disk manager put does on hardware profiler.
Any ideas?

Hi Steve,
As Eric says, you may be able to repair this with 10.4.10 Combo Updater Intel.
This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before. It has worked well for many.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
Good luck.
EDIT: You can't "reverse the patch" without erasing your drive and re-installing. Hopefully, you won't have to.

USB devices won't connect until restart

Hello,
I'm having a problem with my mac. If I turn on my computer and connect a printer / ipod / wireless camera then everything works fine. However, if disconnect the device and try to reconnect it a minute / hour / day later then it doesn't recognise it. If I restart the computer, everything is fine again. I've read about other people having the same problems but there doesn't seem to be a solution.

Usb devices no longer work - after itunes 8 uninstall as well.

Have uninstalled itunes 8 as outlined in various posts on internet. However, now none of my devices such as camera and printer are recognized by my computer. Hope someone has solved this problem. Thanks.

Hello, Emir,
I'd suggest you ask again in the MacBook Pro forum. This forum is intended for old, pre-PowerMac G3 hardware and so not the most likely place to get a quick and applicable response.
Regards.
