iPhone keeps disconnecting from Mac

Since upgrading to Mavericks, I have been unable to sync devices (specifically ipad mini and iphone 4s) to my MId 2013 Macbook Air. They wil rapidly connect and disconnect, and I'm unable to do anything with the device. This happens with both USB ports. Any suggestions?

[Re-Titled by Host]

MacBook Air, OS X Mountain Lion (10.8.5)

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.


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. If you don't see that menu, select

View Show Log List

from the menu bar.


Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

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.

Same issue, also waiting for a solution. Happens with my iPhone5 in combination with MBA and MBP.

I got a spare phone charger and cable through Amazon. The charger gives an error message that it is not certificated and the cable, when used for syncing the phone, caused the computer to disconnect all USB ports, because it was taking too much current.


So I just wondered if people here are using authentic Apple cables?
