Does a PC for analysis of LE-620HS have to be able to support USB2.0? Is it possible to operate LE-620HS on a PC that supports USB1.1?
USB2.0 is not necessary. You can operate LE-620HS on a PC that supports USB1.1. The possibility of overrun etc. rises, because the transmission capability to a PC will become lower. We therefore highly recommend you to use a PC that supports USB2.0.
