Crash when plug or unplug USB device

I have a Mac Book Pro that I plug into a Raritan KVM switch and use to sync files between the laptop and my desktop machine. I've been doing this for years with no problems, until I installed the Leopard OS. Now either when I plug in the USB connector, or unplug it, the computer will crash about half the time. What I mean by crash is that I get the grey background screen and the message that says,
"You must restart your computer...." What is the deal with this? I'm plugging in a USB device and it
brings down the entire computer. Like I said, this NEVER happened until I got this new OS upgrade.
If I had known how unreliable this OS release was going to be, I never would have put it on the laptop.
I have been an Apple customer ever since 1984 because I just want a computer to work, and not go
through all this stupid crap. I just updated to version 10.5.3 with the hopes that would fix it,
but I guess it's too much to ask these days just to have it work. Is Apple infected with Windows
now that it runs on Intel hardware? I don't know, but my confidence has gone down a lot.

Hi.
I assume you have exhausted all the Repair Permission and using Single User Mode to 'repair' the disk; and still encounter this problem.
I wouldn't totally blame the OS Upgrade but I also understand that you may not get the finer details of whether the new update is compatible with all the devices etc that we use daily with the computers.
But in your case, it is most likely the new OS is somehow incompatible with the switch. I had one time a USB Bluetooth adapter that everytime I leave it plug-in and when shutdown my mac, kernel panic occurs (that's what you are experiencing)
See if you can isolate and confirm whether this is a new OS compatibility issue, by using another mac with an older OS or something, also check with the switch's manufacturer if there is a newer model or able to do some sort of firmware upgrade?
I know this really doesn't help your immediate problem but think you have to understand this, that whenever they have a newer upgrade or newer OS, or a piece of hardware, some "older parts" have to be chuck, if not, the new OS would be too huge and balloon up, or cause complications - that's my theory anyway; Like with the new macs and new OS, I can no longer run Classic which is still quite vital to some of my daily work, but "no choice" I just have to find some other way to work around it, because without the new hard and software, I also wouldn't be able to enjoy the new and speedier applications like the Adobe CS3 suite.
Cheers

Windows Explorer crashes when plugging or unplugging ipod touch

Seems something is buggy with Itunes 7 or the Ipod Touch itself. This happens to me on 2 different computers, one Dell and one HP so I doubt seriously if it is the computers themselves. All of my drivers on both systems are up to date.
When I plug in the IPOD it will work and sync, however when I unplug it I get a windows explorer crash each time. Needless to say this is irritating as heck.
Anyone else having this problem?
thanks

I have the same problem, even when i use the eject button. I hate vista but on my pc i have no choice but to run it. Never had any problems on my Macs. i also get a strange error on work pc running XP. It says at first that it doesn't recognize the device running in compatibility mode but then it switches over and works fine. I tend to blame it on Microsoft crap, maybe they are updating their OSes to mess with Apple products.

Had the same issue. Tried everything that was posted for troubleshooting bye apple and on the discussions.
Finally, tried something that solved it and it works flawlessly now. I changed my wireless router.
I was using my ISP's supplied ZyXEL PN660 ADLS2+ with Wireless N. Swtiched to an older Linksys WRT160N and it is working beautifully now.
Take a look at your router, make sure the firmware is up to date, and that UPnP is enabled, and if all is correct, and you have done everything else, try another Wireless router if you can.

After installing Lion on my Mac mini I no longer get a sound whe I plug in a usb device, and sometimes iTunes does not recognize my iPad. Is this normal (lack of usb recognition sound)?

After installing Lion on my mini, I no longer get a "recognition sound" when I plug in a usb device. Is this normal?

I am not sure any Mac every had a sound for plugging/unplugging USB devices.
You may be right. It's only on Windows that the sound is created and heard.
I know that since Tiger on this MBP, when I plug in my external scanner, I never heard anything.
And plugging in my Blu-Ray recorder also does not make any sounds.
I cannot speak for anything but my Mac laptops, however. Desktop Macs might make a sound.

Is it safe to plug and unplug USB and Firewire cables with the computers on

Is it safe to plug and unplug USB and Firewire cables with the computers on? I have a Mac G4 and a newly purchased IMac and I use one printer for both computers. Should I shut down the computers when I unplug the printer and connect to the other computer? How about when switching firewire drives.
Is there an easy way to have both computers connected to the same printer? I have an Epson 1280 printer.

USB/Firewire ports were designed to be "hot" plugged. You can safely plug and unplug devices without usually having to shut down the computer or the device. Some devices, such as external HDs, digital cameras and iPods need to be "ejected" first, so as not to damage their formatting or data.
You can network your Macs wirelessly or with an ethernet cable and then set the printer connected to one computer to be shared with the other computer.

Iphone seems to take a long time to charge when plugged in to USB

Hi MyIphone seems to take a long time to charge when plugged in to USB. Is this normal? Less power coming from the Laptop than wall plug?

Wow.. this completely amazes me. USB is 5v. Some computers (especially laptops) will shut off power to USB devices when the computer enters power saving mode. Very few will lower the power (since this could actually damage a device). I have noticed no difference in charge time between USB and the wall plug (I use the wall plug mostly when I travel, and USB at home). The only difference I can see is the wall wart puts out slightly more amperage then a USB port.

Yes, you can unplug a printer without shutting down the computer, but if you are switching the printer to another computer then you should first turn off the printer, unplug it, re-connect to the other computer, then turn on the printer. This will assure that the printer will be properly recognized.
If you have your computers networked via Ethernet then you can leave the printer connected to one computer and share it with the other via the network connection. Printer sharing is turned on using the Sharing preference in System Preferences. You will need to Add the printer on both computers so you will need the appropriate printer driver installed on both computers.

How to make external devices (like iPods, etc.) NOT mount as connected drives when plugged in via USB to a Mac?

If I plug my iPod (or a thumb drive or whatever) to my Mac's USB port, the device appears as a icon representing a connected drive on my Mac's Desktop.
This is normal, expected behavior.
HOWEVER, in some cases, I'd prefer that the device not "mount" as a connected external drive.
With thumb drives or external USB drive, of course, I want them to "mount" so I can transfer files on or off them -- that would be the only possible reason to connect an external drive like that.
But with other Apple devices like iPods or iPhones, there are TWO possible reasons to connect them to a Mac: either to "sync" them or transfer files on/off them; OR, to simply recharge the device's battery. (Or, both sync and recharging functions at once.)
For those people who use their Apple devices in ways that require transferring files (i.e. most people), then having the device "mount" as a connected device is a desirable behavior.
But in my circumstance (and I bet there are a lot of people in a similar circumstance), I have no need or desire to transfer any data to or from my device every time I plug it into my Mac: I'm plugging it in SOLELY to recharge the device's battery.
Specifically, in my case, I have a 6th-gen iPod Nano, and I use it exclusively as an FM radio and a pedometer. I don't have any mp3s or songs or any other external files loaded on it, nor do I plan to add any in the future.
The only reason I ever plug it into my Mac is so that I can recharge the iPod's battery.
But the "problem," which is a minor one I admit but a problem nonetheless, is that every time I connect the iPod to the Mac, the iPod appears as a "connected drive" icon on my Mac's desktop. Which means that I'm not supposed to just unplug the iPod when I'm done -- first, I have to find its icon on the Mac Desktop, and then drag the icon to the Trash, to "unmount" it -- and only then can I freely unplug the iPod without getting an error message telling me that I shouldn't just disconnect connected drives without first properly unmounting them.
This would be bothersome enough if I only had to do it once per connection, but in the case of the iPod Nano, there's no way to tell how recharged it is while it is in the act of recharging, so that to see if I'm "done," I have to unplug it, check the battery status, and if it's not fully charged, re-plug it back in. So that each time I recharge it, I often have to unmount the drive several times, depending on how impatient I am.
There has to be a way to prevent the mounting of the drives of devices that one is connecting simply for the purpose of recharging. But how?
Strangely, I also have an old iPhone, and when I plug that in for recharging in the same way, it DOESN'T appear as a connected drive on the Desktop. I'm not sure how I managed to do this, but long ago I must have changed some setting or preference for this to happen. And by now I've forgotten what I did.
I'd prefer that I could change the "mount/don't-mount" setting on a device-by-device basis -- i.e. make it such that this particular iPod doesn't load, but perhaps a different iPod would load -- but if that's not possible, then is there a way to stop ALL iPods and iPhones from loading as connected drives when plugged in?
(I'm not talking about appearing as connected drives within iTunes -- I'm talking about appearing as an icon on the Desktop in the Finder.)
And please don't tell me to just buy a wall charger! I prefer to recharge off my computer if possible, using the charging cord that came with the iPod.
I presume there's some simple setting to toggle this on or off, but I haven't yet found it. Any clues would be appreciated. Thanks!

Well, I already know about that Finder Preferences option, but that is not what I'm looking for. Why not? Because I still need CDs and DVDs to appear on the Desktop and mount properly! If I uncheck the "CDs, DVDs and iPods" option, then I lose the ability to access CDs and DVDs, which creates a whole new problem for me. What I want is to not mount iPods only -- actually, what I really want is to not mount this particular iPod -- but if that level of specificity is not possible, then I want to exclude just iPods from mounting, without also condemning CDs and DVDs (or whatever) to invisibility.
Also, I was confused by the way the Preference is worded: It says "Show these items on the Desktop," with a series of options to check. But this phraseology seems to mean that the unchecked items will still "mount," they simply won't appear as Desktop icons. One would still have to "Eject" them using a menu command, rather than dragging the icon to the Trash -- right? Or am I mistaken, and is the Preference Pane simply badly worded, and when they say "Show these items on the Desktop," what they really mean is "mount these external devices as connected drives." So that if a category is unchecked, then they won't load as external drives at all?
But if so, then what purpose could possibly be served by inserting a CD or DVD that is not recognized by the computer? And if it isn't recognized, then it would seem that there would be no way to ever Eject the CD or DVD disk. Right?
Thus, if I uncheck that Finder Preference box you suggest, one of two outcomes will result:
-- Either CD, DVDs and iPods are still mounted, they just won't appear as icons on the Desktop; but they would still need to be Ejected via a menu command, which doesn't solve my problem.
-- Or, CDs, DVDs and iPods are not mounted or recognized by the computer at all, which means that if I insert a disk into the disk drive, it will get stuck there forever, since there's no way to Eject it, since the OS doesn't recognize that it's even there. Which is thereby a new problem.
Either way, I'd have a problem! Or...? Clarification, anyone?

My MacBook Air freezes when I plug in any usb device or open iPhoto. Please Help?

I have a MacBook Air that is currently running Mountain Lion OS X (version 10.8.2). Every time that I plug in any type of USB device (trackpad, USB jumpdrive, Time Machine, etc.) my mac freezes and I have to shut it down via the power button. The same issue occurs whenever I open iPhoto. Has anyone else ran into this issue or know how I can fix this? Any help on this issue would be greatly appreciated!!
Thanks!

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console 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 Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them (command-C) to the Clipboard. Paste (command-V) into a reply to this message. Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.
