IPAD2 is not recognized by my IMAC i7

Question

I've read just about everything in the forums, both relavent and not relavent to my problem, including the links some answers included.
I have a new WIFI IPAD2 which I purchased about six months ago.  I have been charging and syncing it with my IMAC i7 Quad, which I have had less then a year.  I plugged my IPAD into the IMAC today and it would not charge or be recognized by Itunes(10.3.1).  The IPAD would charge on the wall outlet.  All programs and OS are current.  I followed some suggestion found in the forums.  One appeared to start to work, but I had to RESTORE the IPAD.  So I went through that process but when it started to load I got the 1611 error message.  I tried it again using different USB ports on the IMAC, no joy.  So now I have a wiped IPAD2.  I dug  out an old IMAC I had in the basement and did the same thing.  After updating the IMAC's software, it did go into the RESTORE mode.  It's not completely done yet but the Apps are loaded and it is almost done.  But it isn't charging. I hope I have enough power to complete the process.   I'm assuming it's because it's an older model it won't charge.  How do I get this IPAD2 to be recognized by my newer IMAC?
I also, for grins, plugged in my IPOD4.  It also is not recognized by iTunes on the new IMAC, which I use all the time with my IPOD4.  But, it does charge on the IMAC.
Any Ideas?
