PROGMEM causes a section conflict

[MatteGary]

Hi, i can't run any sketches from the PTP_20 library. I tried using Arduino Ide 1.0.2, 1.0.5, 1.5.6, 0.2.2...

For example, from the PTPDevInfo sketch I get a lot of "*** causes a section type conflict", and from the EOSCapture sketch I get a lot of error like ".../usbhost.h:21:2: error: #error "Never include usbhost.h directly; include Usb.h instead", and from NKRemote sketch I get same error from EOSCapture plus some type and scope error.

There's anything you can tell me to do in order to make this library work correctly?

Thanks
