thx for the infomation. what an interesting information u provide. i really hope to test and handle the HS device but too bad my Host controller does not support HS speed, really sad that i only able to keep the FS setting. If not i can share my experience here. thx alot...
another noob question again, i had successfully set the configuration for the USB device, do i need to set interface as well? if my device only hv 1 configuration,1 interface, and 2 endpoint descriptor. izzit by default when i set the configuration, it will automatically select the default interface, and the endpoint?
for some device have afew different interface..on that case than only i need to used the set interface command if i need to select a different interface? am i right?
there something is confuse me is the bNumInterfaces field in configuration descriptor and bInterfaceNumber field in interface descriptor.
the bNumInterfaces contain a value 0x01, does it mean i had 1 interface and bInterfaceNumber contain a value 0x00, so does it mean that the only 1 interface number is 0x00? hope i dint get it wrong here...
