In the past I've found some OS (namely, Windows XP) have problems managing more than 12 USB devices.
1. Will the PhidgetsSBC2 have any issues managing 17 to 20 USB devices (using multiple hubs as required) assuming I give it the 2.5 Watts of power per device as mentioned in the specs?
2. Otherwise, which would be the reasonable limit of USB devices for the PhidgetsSBC2 (using multiple hubs as required)?SETUP DETAILS
I'm currently working in a project that involves reading from 32 Force Sensing Resistors (4 Flexiforce
and 28 Interlink
) and 28 strain gauges.
- For reading the Force Sensing Resistors I plan to use four 1018 I/O Phidgets boards
(each I/O board has 8 analogic inputs hence 8 boards * 4 inputs = 32).
- For reading the Strain Gauges I plan to use thirteen 1046 4-Input Bridges
using wheatstone bridges (each bridge has 4 inputs hence 12 bridges * 4 inputs = 28)
Instead of running 17 USB cables to the computer I thought of using the 1072 PhidgetsSBC2
with three 4-ports USB hubs and put everything into a box and simply running a long ethernet cable to the computer.
