After the 1.1.2 firmware upgrade I keep getting a 0xE800001 Error in iTunes and iTunes doesn't see the phone. Sometimes iTunes works, sometimes it syncs super super slowly. Anyone have any ideas what's going on?
Dual Core 2.3,
Mac OS X (10.4.3),
I also use 1.8G5 and several powerbooks.
I don't know what's going on. I thought I was having problems because my computer is old...but I see that you have much newer computers but we are having the same problem. ;(
Are you connecting through a USB hub, or directly to the computer? Most times I have seen this error its been when working with a USB hub, sometimes a USB 1.1 hub.
Have you tried a different port with only the iPhone, keyboard and mouse connected?
Essentially that error appear to indicate a point in the USB transfer that something went wrong. It can often be due to a timeout, such as have USB 1.1 involved.
Essentially if you have a chain of things on the USB bus such as Port -> Hub -> Device. If any of the 3 items either the port or the hub are USB 1.1, then the device will be connected at USB 1.1 speeds.
