Running two liquidctl processes causes Corsair H100i PRO XT to stop responding to read requests. #274
Description
I've noticed this twice now; after a while (don't think it's X time but rather X read requests) my H100i PRO XT stops responding. The reason for me thinking it's X reads is that both times this has happend I've had a while 1; do sleep; liquidctl status; done loop running.
I've tried rm-ing usbhid module and loading it again.
I can write, but the process hangs after this:

Update from @jonasmalacofilho:
This is now being tracked by issue #298 ("Synchronized access to devices"), where several problems with obvious solutions have already been pointed out. New comments should be directed there.
