I note that the Optio MX will support USB 2.0 - which means it looks promising for future Pentax DSLRs too, I guess.
According to Imaging Resource, the ist-D runs USB 2.0:
"While the manual claims that the *ist D only supports the USB v1.1 interface standard, my own tests seemed to show that it's actually running at USB v2.0 speeds...."
My own informal tests bear this out: My ist-D downloads *much* faster into a USB 2.0 connection than it does into a USB 1.1 connection.
This was mentioned on the list a while back, my response was as follows:
I loaded a file of almost 1GB on my Ridata 52x Pro card and found the following Card read results:
X-Drive II via USB2 (add on PCI Via card) 3668kB/s *ist D via USB2 (add on PCI Via card) 912kB/s *ist D via USB1.1 (embedded on m/b) 932kB/s
The USB 1.1 serial data transfer speed is quoted as 12Mb/s so in each case the *ist D transfer speed is within that specification and what I would expect including serial transfer protocol overheads.
