Hi ,
I have an project where in i need to share a USB mass Storage Device
among two HOST PC's. The hosts would not use the Shared resource at the

same time. So I planned to use 4 SPDT Swithes to switch the Storage
device when ever required. When I did implemented this, I found that
the Mass Storage device was not recognized by either of the PC's. Could

anyone explain the reason and method to implement such a solution
Regards

keep the D+/white and D-/green wires twisted for as much of their
length as possible.

istm you may need to ensure that the power terminals (ground/black and +5/red) are
connected first and disconnected last as the plugs are designed to connect
the power terminals before the data terminals.

Bye.
