I am debugging an issue attempting to manage multiple macs through a TESmart KVM switch and a PiKVM. Everything works beautifully if the PiKVM is hooked up directly to the mac. Unfortunately, with the TESmart switch in the middle, the mac display goes dark after 30s or so. AllRez (https://github.com/joevt/AllRez) output from both the direct attach and with the temsart in the middle are attached.
Of particular note (to me at least) is that the HDCP status differs. Without the TESmart switch in the middle, HDCP is disabled:
68028h AUX_HDCP_BCAPS: BCAPS_HDCP_CAPABLE, BCAPS_REPEATER_PRESENT 68029h AUX_HDCP_BSTATUS: BSTATUS_LINK_FAILURE
