The Geek LPS/LPS4 was designed with the Geek Out and Geek Pulse in mind, both of which are USB 2.0 devices.
While the LPS/LPS4 are compatible with, and tested with, many USB 1.1 devices, we have not been able to test all devices and cannot guarantee the LPS/LPS4 will work with any given USB 1.1 device.
