SkyeModule Gemini Datasheet
11.1 USB 2.0
As a USB device, the host detects the SkyeModule Gemini as an HID device. The SkyeModule Gemini
uses a standard HID driver but is not a certified USB device. The SkyeModule Gemini supports both
standard and high speed USB hosts and enumerates correctly on both Windows and UNIX platforms.
The USB interface is typically only used for demonstration as a USB host controller is not usually
available for in embedded systems. To communicate with the reader in USB mode, either SkyeTek
demonstration software or the SkyeTek APIs can be used. See the SkyeTek support site for the latest
software and API downloads at support.skyetek.com.
Figure 11-1 shows an example of a circuit to permit USB communications without using the host interface
board.
NOTE
device, 500mA at 5V.
– If powered by USB, the USB host must be capable of supplying the USB standard high power
