How are devices connected to the USB, what is right, left, and what is on the hub?

If you turn the laptop off and then boot it up while it is connected to the FMS, then it will not find the Cypress board unless you reboot it twice without the FMS. This killed us twice. We also found that once it looses comm to the Cypress board, it keeps sending old data to the cRio, so there is no simple way to detect this loss. We had one Logitech gamepad and the Cypress board connected to the KOP hub, with both ethernet cables on the hub connected to the Classmate. No problems at all during testing at home. Talking to other teams at Kettering, most of the teams that used the Cypress board had a problem with it of some sort. As a side note, it is really annoying how the Cypress board operates on 3.3v while everything else in the system is 5v, they could have picked a better IO board.
