My new 2010 iMac 21.5" is "on order" and expected to arrive before Aug 20 (due to my remote locaton). Like many, I have lots of USB devices. For most optiminal connection, how would you connect them? USB Devices are: - Backup APC 1300VA LCD unit. - Large keyboard within numeric pad. - HP F4480 Printer - IPod Touch - Digital camera (with large memory card). - future My Book 1 TD external HDD. Was thinking of: - iMac Port 1 - 'future' My Book 1 TB external HDD. - iMac Port 2 - HP F4480 Printer - iMac Port 3 - Backup APC 1300VA LCD unit. - iMac Port 4 - external 4 port USB Hub. "Power Hub" - connected to Backup APC unit. - 4 Port USB Hub - Port 1 - IPod Touch - 4 Port USB Hub - Port 2 - Digital camera (with large memory card). - 4 Port USB Hub - Port 3 - Large size "wired" keyboard - 4 Port USB Hub - Port 4 - forward facing uner iMac unit - for easy plug in of other things (when needed). Is this a good "optimal" configuration of USB ports? Sorry if "silly question" for the well experienced. Just wondering if physcially shared USB ports need to be optimized (for best data transfer usage). thanks. .
