IMovie (and iMac) does not recognize device(s)

Hello and thanks for reading. I know this topic is like beating a dead horse but this one is unique. I'm a professional editor and I couldn't figure this out so any help would be appreciated. Here's the play by play:
I edit using FCP 5.1.4 and have for years. I've had the same set up running for years and do high volume editing.
I have a chain of 4 Lacie drives, all connected by firewire.
At the end of that string, I have my tape player for capturing footage, a Sony GV-HD700, which then goes on to the TVs, DVD players, etc.
Also the end of that string, I also have a disc burner for making DVDs.
So it goes: iMac > Lacie #1 > Lacie #2 > Lacie #3 > Lacie #4 > Sony tape player & DVD burner > TVs, VCRs, etc.
Yesterday, I was in a rush and the DVD burner was going slow so I unplugged it from the end of the string of Lacie drives and plugged it directly into the back of the computer to see if it would burn faster.
It didn't, so I plugged it back into the end of the Lacie string.
At that point, Lacie #4 became unrecognizable to the computer and therefore so was the tape player, which is further down the chain.
When I plugged the tape player high up the chain, into Lacie #3, it still was not recognized.
I plugged the tape player (Sony GV-HD700) directly into the back of the computer...still not recognized.
I took the Sony GV-HD700 into our other editing bay and it was still not recognized.
I pulled out my camera (Sony HDR-FX1000) and plugged it directly into the back of the original computer...recognized just fine.
I plugged Sony HDR-FX1000 camera into the back of Lacie #2...recognized just fine.
I took the Sony HDR-FX1000 camera into our other editing bay...recognized just fine.
I have a big deadline so I said "Screw it." and was just going to capture from the camera for the time being.
I reset the Lacie drive chain, plugged the Camera into the back of Lacie #4 (just like the original setup) and BANG: Lacie #4 and the Sony HDR-FX1000 camera was not recognized.
I plugged the Sony HDR-FX1000 camera directly into the back of the computer...still not recognized.
I took the Sony HDR-FX1000 camera into our other editing bay...still not recognized.
I thought it might be a Final Cut Pro issue so I pulled up iMovie and it does not recognize any device connected to the computer even though I'm looking directly at it plugged in.
The entire iMac has lost the ability to recognize devices that I've used for years. I've now lost the ability to capture footage and I'm running out of time. It's almost as if the devices were getting infected by one of the Lacie drives (I think Lacie #4). Is that even possible? Has anyone ever heard of something like this? I don't know if it's something I need to change on the iMac to recognize them again, or if it's a setting on the device to reset the connection, or if somehow the Lacie drive corrupted the devices and made them unrecognizable to iMacs.
It's very, very weird.
Thanks for your help.
27" iMac (2009)
OS X 10.8.5
Final Cut Pro 5.1.4
Tape player: Sony GV-HD700
Camera: Sony HDR-FX1000
I've had this setup for years so I don't know what type firewire it is.

Try putting it into "Disk Mode" http://docs.info.apple.com/article.html?artnum=93651
Then with it in this mode connect it to the PC and try to run the latest iPod updater to do a restore and update software if you have the option. the latest iPod updater is 2006-03-23 and can be downloaded here http://www.apple.com/ipod/download/

As I said above, some of the new lightning cables have been known to be causing problems for some users. Have it replaced if at all possible by bringing it into your local Apple Store's Genius Bar.

I would first try unplugging All the USB devices plugged into your computer, and then plug back in just the iPhone and see if that is recognized. Also, do you have the latest version of iTunes for Windows installed on your PC, as you need to?
Hope this helps

I connected my sons Ipod Touch to my pc and it worked fine. Now, when I try to connect my iPad the following message comes up: One of the usb devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.
I checked the cable. It surely is not the cable. If I connect the iPod again it works fine. If I use the same cable with my pc and ipad at work or my other son’s laptop, it is working perfectly. It is only on my laptop where the iPod was connected. Something tells me it got something to do with the drivers that went corrupt or something when I connected the iPod.
I searched the internet and I see a lot of people gets this message. Still no solved answers yet. Is there a place where I can download the drivers again or any other suggestions?
Windows 7 and iPad 2
Kind regards,

I was hoping it would be something like a USB device conflict, but now the shuffle is the only thing connected...

Under Part 9. Verify that USB drivers are installed, did you try the steps in If only "Unknown Device" appears? That appears to be your situation.
Also, you said that the shuffle initially worked well enough to do a sync, then it had the same problem again. If you can get it to work again initially, before doing anything else, try the following. Select the shuffle in the iTunes sidebar, under DEVICES. Over to the right, go to the Summary tab. By default, the checkbox for Enable disk use should be unchecked. If so, check it and Apply the change. See if that makes any difference.
(If Enable disk use was already checked, try unchecking it and Apply the change. Basically, set it the "other way" and see if there is any improvement.)
NOTE: When disk use is enabled, you have to eject the iPod in iTunes before disconnecting it physically.
If the disk use change makes a difference, that may provide a clue about the actual cause.

You are installing the Apple Mobile Device USB driver, which I did not have to do previously, so something in the updates has been left out / or changed.

My computer will not recognize my iPod Nano when i connect it. I tried my laptop instead but it said the same thing - one of the USB devices attached to your computer has malfunctioned, and windows does not recognize it. Can i fix this?

My 16 gig iPod Nano 7th gen was put of power. I connected it to the computer and it started to turn on (the apple appeared in the middle of the screen). Then left it two minutes and the computer went into sleep mode. My iPod nano had gone off and now it will not turn on, or connect to the computer, so i cannot charge it. I am not sure if it is a problem with the usb cable. When I conntct the cable to the computer nothing happens, but then when i connect the iPod to the cable it says 'one of the USB devices attached to your computer has malfunctioned, and windows does not recognize it'. Please don't say its broken already

It probably needs to be reset. The procedure is different for different Nano models: http://www.apple.com/support/ipodnano/assistant/itunes/

Ipod touch wont load past apple screen. I have tried resetting by holding home button and on/off but after it resets it still only loads to the apple screen. When I plug the device in It stays on the apple screen and itunes does not recognize it?

Ipod touch wont load past apple screen. I have tried resetting by holding home button and on/off but after it resets it still only loads to the apple screen. When I plug the device in It stays on the apple screen and itunes does not recognize it? I fear it may be stuck in some sort of reset loop which is stopping itunes from recognizing it. How do I go about the process of sending it in to apple if I cannot find a fix? Thank you in advance, it is greatly appreciated!!

- See if placing the iPod in Recovery mode will allow a restore.
- If not successful and you can't turn the iPod fully off (that is required to place in recovery mode), then let the battery fully drain. After charging for at least an hour try the reset, restore again
- Then time for an appointment at the Genius Bar of an Apples store.

HT4623 e while updating iOS. When connected to PC & iTunes get the message in recovery mode, must restore. I have followed the steps to restore and still have the iTunes screen showing and iTunes still does not recognize device.

iPad 2 froze while updating iOS 7.0.4. When connected to PC & iTunes get the message in recovery mode, must restore. I have followed the steps to restore and still have the iTunes screen showing and iTunes still does not recognize device.

Sorry if we didn't get to your question fast enough; we are all volunteers doing this in our spare time. Try the steps in this article. If you're unsuccessful, you'll need to take your device to the Genius Bar for an evaluation.

TS2570 iMac does not recognize wifi keyboard and track pad... cursor stays in top left corner under apple ?...

iMac does not recognize wifi keyboard and track pad... cursor stays in top left corner under apple ?...

Phillip,
I had this problem recently with a 3-year old Mac Pro intel, which was eventually replaced by Apple due to myriad other problems. When the frozen mouse happened, there was nothing I could do. Very frustrating to have the screen boot and the cursor is up there stuck, on the top left corner of the screen. Frozen. I called support several times. They were amazed. At one point they had me buy a cheap USB mouse (I was using a wireless mouse from Logitech and they thought there might be some kind of conflict). The USB mouse didn't work, either. Neither did an Apple mouse when I went out to buy one.
I ended up driving 70 miles to take the Mac to an Apple Store. I think they reinstalled the (Leopard) system in some secret way, because when the mouse was frozen so was everything else and I couldn't open the disk drive to put the OSX disk in there.
Why I'm here right now is that the same thing happened today with my NEW 3-month-old REPLACEMENT MAC PRO using its brand new wireless mouse, and I was hoping to find some insight. Again, a frozen cursor after the boot. Same top-left corner of the screen. Unlike you, when I click the mouse nothing happens -- no drop down.
Luckily, when I hard-rebooted by holding the button in, the mouse cursor came back. This time. Now I am afraid to turn my computer off. Been there done that before. Anyone have suggestions?
Thanks in advance.
