Photos from iPad corrupt after import with Image Capture

Here is a link to an archived thread from 2009 in which several people complained about slow transfer speeds from various types of digital cameras when using Image Capture in Snow Leopard:

Nobody ever replied to that thread to indicate that there might be any real help for this problem. However none of those people complained of corrupted files, either, so the slowness and the corruption would seem to be seperate issues. Thoughts?

I also found this link where Apple mentions corrupted files and slow transfer times as symptoms, and how to troubleshoot the USB download issues with iOS devices like iPad and iPhone:

I'm trying their tips along with updating any and all related USB device drivers and USB programs:

TabletMagic

ControllerMate

Yamaha USB Midi driver

Logitech Control Center / GamePad / LCD Manager

I fixed the problem. Now it is downloading photos over USB super fast with no problems.

I hope these steps will help other people who have the same problem.

I did the following steps from the previous post's Apple link:

Once you determine that your computer has a USB 2.0 connection, use the following steps to troubleshoot the connection between the device and the computer. Test after each step:

1. Update to the latest version of iTunes.
2. Plug the device directly into a high-power USB 2.0 port on the computer. If possible, use a USB port on the back of the computer.

   Avoid plugging the device into a keyboard, display, or standalone hub. The USB ports on these accessories may be low-power or only offer USB 1.x connections.

3. If you are using an accessory, remove the device from the dock and connect it to the computer using only the Apple USB to Dock Connector cable.

   If you have access to additional Apple USB to Dock Connector cables, try testing with another if the first one doesn't work.

4. Restart your computer and device. To restart your device:

   Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the Sleep/Wake button to turn it back on.

5. Disconnect all USB devices from your computer, except for your keyboard and mouse. Then reconnect the iOS device. If the issue is resolved, reconnect other USB devices, testing after each connection.

Additional steps I took:

* Quit every app that was running on the iPad, including some that might try to use the MIDI features over the USB connection.

Note: I forgot to mention, I also did these steps, as recommended by this thread: https://discussions.apple.com/thread/2439281?start=0&tstart=0

You will need a USB keyboard and mouse to do this. If you only have Bluetooth keyboard and mouse, then I guess don't deactivate it all the way, but at least remove any non-essential devices and ports.

1) Go to System Preferences: Bluetooth preference pane

2) deactivate Bluetooth

3) remove all devices from Bluetooth preferences

4) in Advanced, uncheck every box, like the Serial Port option, the start at boot-up option, etc.

5) activate, then deactivate, bluetooth

6) restart the Mac

I'm not sure if those steps contributed to fixing the slow USB problem, since I did a lot of other steps along with these, but, these bluetooth steps are steps that have helped others if the thread I linked to in this message is any indication.

I'd like to add that these steps, followed exactly (including the BlueTooth deactivation steps detailed in the Jan. 2 post directly above) also work in Lion. I was again having the slowness issue downloading photos from iPad (3rd generation iPad this time, but same problem). Doing these steps again did indeed fix it, at least temporarily.

Note: just after selecting restart on the Mac, I disconnected the keyboard and mouse so there were no USB devices attached WHILE it restarts. Once it reached the login screen, I connected an Apple brand aluminum thin keyboard to the front USB ports, and a Kensington optical mouse (which itself is 10 years old). Then I connected the iPad to the rear USB ports.

I am not sure if the problem is caused by the BlueTooth or by my Logitech keyboard and its drivers. Who knows. If I can determine the cause I will certainly post it here. As if I have time.
