Hi. Now, if we temporarily leave out the question about how much money Wouter will make on this deal, I have a slightly more technical question... :-) I understand that the VID/PID can/will be used to automaticly load the "right" driver for a particular product. Now, what if a product uses the standard "HMI/HID/whatever" driver ? What should the VID/PID be in that case ? Can one still use a unique VID/PID so one know that the "right" product is connected ? Can multiple products using this standard driver be connected at the same time ? As I understand it, if you only need simple "serial-like" communication, you can just as well use this (simpler ?) driver, or ? Jan-Erik. PS. A pointer to a "USB-primer" would also be fine, obviously... :-) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
