I've tested with my JRMC17 and JRMC18 in evaluation.
Ipod appear clearly in my Windows 8 (only for photos transfer)
Fully detected in iTunes
I've tried with my installed JRMC17 not succeeding in any way.
Loaded JRMC18 with the same result.
I enclose logging of JRMC17 with iTouch connected
Thanks in advance for your support
