That's me unplugging and replugging a device in different places. Note that the message appears multiple times each time I plug it in.
But this isn't just that one device (a galaxy tab if you're wondering). This happens with so many devices I'm going up the wall. It even happens with USB Flash drives! "I'LL JUST USE A DIFFERENT CABLE OH WAIT COMPUTER YOU'RE AN IDIOT."
Sorry, just so frustrated. I've tried the classic capacitor flush (turn off, hold power button in with power calbe unplugged) and it's been doing this for a while, so updates haven't solved it. Different types of devices too, not just storage. Even a keyboard did it one time. You guys got any ideas at all?
EDIT: Before that inevitable post comes, yes, I've plugged it directly into the ports that are attached to the back of the motherboard, please don't ask, please, please, please. I know someone won't read this whole post and will ask anyway but a guy can try.
EDIT EDIT: I forgot to actually say that usb devices do not work when this message appears.

If the errors are consistent across OS (ie LiveCD, Windows?) then your motherboard is most likely on it's way out and needs replacing
You could try removing the motherboard cell battery and doing the "classic capacitor flush" again. Leaving the battery out for a period of time generally has the same effect and in "classic" IT style fixes numerous woes... have you tried a different cable?
If, after replacing the battery, the problem has disappeared I would still treat the hardware as suspect and have it replaced as soon as possible. These sorts of brain farts typically reappear sooner rather than later

I can tell the differnce when listening to "One More Time" by Daft Punk...
...The 356kb version when compared to a 128kb version I had. The electronic sounds sound a lot more crisper then on the other one...not to mention it doesn't make a fuzzy sound when I turn it up high on the iPod...but then again, like I said in another thread, I also compared "Smile" by Lily Allen and they sounded very much the same. I'm also using noise-cancelling headphones and a brand new audio card so it should be easy to hear the difference when played...to tell you the truth, it's better on a few songs but sound very much the same on other songs...it depends on what the song is and what type of audio equipment you have.

Using the USB cable to sync my blackberry deletes all calendar entries older than 3 mos
I'm not very good at this kind of thing, so please pardon what I'm sure will be mistakes/omissions as I describe my problem.
Every time I sync my blackberry using the USB cable (I'm told by my boyfriend who is an IT guy that I can't sync it wirelessly although I don't know why), all of my calendar entries in Outlook get erased--that is, all the entries that are older than 3 mos. I frequently use those entries as reference so I can't lose them--so now I'm terrified to sync my blackberry.
Any help will be much appreciated!
JennyI just found this on the support page and am going to try it for a couple of days to see if it solves the problem:

Overview
When synchronizing the Calendar via the BlackBerry Desktop Manager, past calendar events are being deleted on the desktop calendar application.
Cause
Calendar items on the BlackBerry smartphone were deleted as a result of the keep appointments setting in the Calendar was set to delete older appointments.
Resolution
To resolve this issue, complete the following steps:
Task 1
Configure the BlackBerry smartphone to keep past appointments:
Open the Calendar application on the BlackBerry smartphone and press the Menu key.
Select Options and then General Options.
Within General Options set the Keep Appointments options to Forever.
Task 2
Configure BlackBerry Desktop Manager calendar synchronization options:
For BlackBerry Desktop Manager version 4.5 to 5.0:
Connect the BlackBerry smartphone to the computer with a USB cable and open BlackBerry Desktop Manager.
Select Synchronize from the main menu of BlackBerry Desktop Manager.
Select the Synchronization link and click on the button labeled Synchronization to configure the synchronization settings on the BlackBerry smartphone.
Select the Calendar.
Select the option to Synchronize with Microsoft Outlook and click Next.
Select either the Two way or One way sync and click Next.
Select the Default profile for Microsoft Outlook.
For the Calendar date range select the option to Synchronize items within a range of days, configure the date range to sync 30 days in the past and 365 days in the future.
Click Next.
Continue through the configuration wizard and click Finish and then OK.
Perform a new synchronization.
For BlackBerry Desktop Manager version 4.2 and 4.3:
Connect the BlackBerry smartphone to the computer with a USB cable and open BlackBerry Desktop Manager.
Select Synchronize from the main menu of BlackBerry Desktop Manager.
Click on the Configuration tab and then on Configure Sync.

Click Next.
Continue through the configuration wizard and click Finish and then OK.
Perform a new synchronization.
If you are still prompted to make deletions from Microsoft Outlook for past calendar events that were not manually deleted, then you may need to repeat the steps above and synchronize with a smaller date range for past events.
For BlackBerry Desktop Manager version 1.0 for Mac OS:
Connect the BlackBerry smartphone to the Mac with a USB cable and open BlackBerry Desktop Manager.
Select Calendar.
Select Two-Way.
Select All Calendars or Selected Calendar, checkmark calendars to use during synchronization.

IPad will not connect to pc or iTunes, I get a double ping when I connect the USB cable
My iPad will not connect to either my PC or iTunes. When I plug in the USB cable I get a double ping from the PC. Any Suggestions?
I have never heard of this "double ping" issue in the before. You say it is coming from the PC so maybe it is a USB problem on the computer. I assume that you have tried another USB port on the PC. You could also try another computer that is running iTunes and see what happens.
I am not a PC user, so the only other thing I can offer is a link to the Apple support site for an iOS device not being recognized in iTunes for Windows.

I used to be able to just plug in my phone with the USB cable to my Windows 7 computer and browse phone storage with no issues. Now my computer sees it as an android phone but when it tries to automatically install the drivers for my phone on the computer, i get an access denied error message. No option on the phone that i can see that allows me to mount phone as a usb drive. This used to work just fine with nothing more than just hooking up the cable. What gives??
Let's get that access granted again, e_rock_b. The HTC DNA doesn't have a special USB Mass Storage Mode that needs to be turned on. Usually, it's as simple as connecting and browsing http://vz.to/1jktbZD as you mentioned. If your computer is no longer allowing that easy access, try the steps at http://vz.to/1jktvr6.

Neither my iPod Touch nor my iPhone will show up in iTunes when I plug in through the USB cable. My software is updated, I've restarted everything, I've reset the devices, but still no luck. Help?!
Check your System Profiler to see if your computer is recognizing them. You may need to reset the computers SMC.

I'm new to this and I think I typed a long heading!
Anyway the issue is I have iTunes and just updated it to the latest. I also have various Apple devices however my iPhone won't sync with iTunes. When I connect it using the USB cable it does not appear in the top right corner as does other devices. The cable is fine as it charges and also my PC sees the device. However it does not appear in iTunes so I can't sync music to it.
I've searched the web but all asume iTunes can see the device.

cannot charge my daughter's ipod touch nor does the computer acknowledge that it is plugged into the USB cable.
Not Charge
- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genus Bar of an Apple store.
Apple Retail Store - Genius Bar
or
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

And I have touched by accident on the one and i have this small current passing though my hands and then i have touched on the other one to see whats happening and same result. I had just took a shower and barefoot. Then when i put my shoes on. Problem gone!
