Iphone access problem with USB memory inserted on RPi 2

I’ve installed 15.10.1, updated usbmuxd and libimobiledevice-dev to address trust this computer issue but every time I try to access the USB memory the do loop of trying to access the iphone starts up and then indicates the USB and the iphone are not accessible. During boot, I get a failure indication of “Failed to start Load Kernel Modules” and “Failed to find module ‘lp’”, Failed to find module ‘ppdev’, and “Failed to find module ‘parport_pc’”. Thanks in advance for any ideas on what to try next.
