Hi Guys,
Fantastic work on the protocol specification. I got myself a Corsair Link Bridge based on this thread in the hope that it might have somehow worked with the Bridge.
Sadly, even with modified IDs, although I can get a handle to the device in the CorsairLink init, I can't get the ID or anything further.
Has any work been done towards the Analog bridge? I bought this to go in my headless server so I can log some PSU stats, I don't run Windows anywhere so I don't even know what information the PSU can give since I've never been able to run the software.
I have the output of lsusb if it's of any use;
$ sudo lsusb -D /dev/bus/usb/001/002

If I run the modified OpenCorsairLink with the new IDs in place of either the CLINK or the H80I devices I get the following:
$ sudo ./OpenCorsairLink
Open Corsair Link (Cooling Node):
Error: Unable to write() No data available
Device ID: 00 mismatch. Not Corsair Cooling Node
Cannot initialize link.
I get the same thing using the other method and my ID.
Anyone able to point me in the right direction? I have zero experience with HID devices but am happy to write up the rest of the code required to communicate with the device if someone can help get me communicating with it.
