Driving USB Devices From A Stamp
In sure this subject's been covered before, but I can't find it, so apologies in advance.
I have a several·USB devices that I'd like to·connect to·my Stamps. Obviously, these devices were originally designed to be connected to PC. They·have independant power supplies.
Most of the interface boards that I have seen, like USB2SER, appear designed to connect Stamp and PC.
Do I need an interface board·between my Stamp and·my USB devices?
Or can I mix·the 5 volts of the Stamp and the 3.3 volts of USB?
Thanks, John Burrow

Note that USB clients expect to see 5V supplied by their USB host. USB hosts have to have a 5V power source so they can pass on the 5V power to their clients.
Are you aware of anyone that has successfully·used a DataLogger to·send/receive to something other than a memory stick? Or do I have to buy one and experiment?
Thanks, John
