Hello USB Experts,


I am considering using PIC 16C765 with USB interface and have followed some
of the previous discussions on the actual expected throughput to a single
device.

In my project it is important for me to get a command from the PC in
constant time from the time that my PC program decided to issue such
command. By constant, I mean less then 1mS.

Do any of you know if I should expect to see jitter in timing between the
time that my program on the PC decide to send a message to my PIC
controller to the time that this message is actually being transmitted. One
such reason would be that the USB host has a predefined time slot for
communicating with a particular USB device and a message to that device
would not go immediately as my program request it, but, will wait for it's
time slot.


Thanks Chaipi
