Plugin to control USB relay "For Smart Home" (eBay phrase).
Some of the information comes from the site Driver-less USB relays (HID interface).
This series of relay boards, it is far superior to the ICS series.
The great advantage is that it uses the HID technology, so no need to install any driver in windows system.
Compared to ICS series, we can even read the current status of each channel.
Unfortunately, even these devices are not quite perfect.
They have one major flaw:
Windows (XP, 7, 8, 10) fails to recognize these devices on some PCs (complains that device descriptors cannot be read).
Possible workaround:
When connected thru a USB hub, these devices are properly detected.
Note: I have experienced that in some cases, this workaround is not working (eg. my Lenovo laptop).
