The SiLabs Si7005USB-Dongle is a USB-based temperature and humidity logger.
It's actually an eval board for the SiLabs Si7005 humidity and temperature sensor, but can be used as USB-based logger too, of course.
See SiLabs Si7005USB-Dongle/Info for more details (such as lsusb -vvv output) about the device.
