Unless I am mistaken, the USB specs stipulate that it shall be possible to connect up to 127 USB devices to a PC.
So what you want to do should be doable. However I don't know the chances of it exposing bugs in the Linux USB subsystem, as it is a rare use case. However, if you are providing hardware to the competitors anyway, why not issue them a WiFi enabled device, and then have your server collect information via TCP/IP (such as by having them surf to a Website which does the answer collection). --- Omer On Wed, 2011-04-06 at 07:44 +0300, yosi yarchi wrote: > Hi all > > > I need application that will be able to collect and process inputs from > 30 (!) competitors, and will display the results very fast.
