Bug in calibre 0.7.5 on Mac related to iTunes

[lmamakos]

I upgraded calibre on my fancy iMac and noticed that it wasn't detected my Sony PRS-600 device (which has previously worked just fine.) After some amount of poking around, it seems to be related to iTunes running or not when I start calibre. I ran calibre-debug in the two circumstances which might shed some light on the issue.

Here's what happens when iTunes is already running:

If I quit the iTunes application, and re-run calibre-debug, I seem to get something that works. I notice during this process that iTunes gets launched and then the window is minimized or closed.

I can seeming use Calibre with success if I remember to exit iTunes before launching. It would be nice to avoid launching itunes just to probe for the iPad that I don't own and speed up the Sony device detection.

Hope this is helpful!

[Elnino]

I have the same problem with Windows 7 and my Sony 505. When I start Calibre it is automatically launching Itunes and my device isn't detected in Calibre.

[GRiker]

@Imamakos: You have an iPhone plugged in, which is a recognized iDevice.

If you don't want calibre to detect your iPhone as a Reader, you can disable the Apple driver in Preference|Plugins|Device interface plugins.

More information available on the 0.7.5 updates in 'Calibre 0.7 + iPad: Start here'.

[Elnino]

GRiker - thanks that fix worked for me as well as I was charging my Iphone.

[lmamakos]

Yes, an iPhone is plugged in, but you'll note that at least calibre-test fails with an error. When I run Calibre it doesn't find any devices, including the Sony.

[GRiker]

The reason you're not seeing any devices is that your iPhone is still physically connected to your computer while charging, but ejected from iTunes. It's still detected as a physical USB device on the bus, even though you ejected it in iTunes. Calibre sees it and tries to mount it as a device, but fails because it's been ejected.

If you want to see your iPhone in calibre, physically disconnect the iPhone from the computer, then reconnect and run calibre again. If you want to see your Sony, follow the directions I supplied earlier to disable the apple driver, or run calibre with the iPhone physically disconnected. If you want learn more about the apple driver, see the 'Calibre + iPad: Start here' thread.
