+Upgraded QBSC firmware from .189 to .190
+Compiled plugin w/ API 3.67 by commenting out all code related to setting SYNC param.
+Initially plugin wouldn't load. Dependency walker showed it was linking to NeuropixAPI_x64_3_67_dbg.dll.
+Renaming NeuropixAPI_x64_3_67.dll to NeuropixAPI_x64_3_67_dbg.dll enabled the plugin to load properly.
+
+I was able to connect to one headstage and one probe: 
+
+[open-ephys] Scanning for devices...
+[open-ephys]   Found 1 device.
+[open-ephys]   Opening device on slot 4
+[open-ephys]   Opened BS on slot 4
+[open-ephys]   BS firmware: 2.0169
+[open-ephys]     Searching for probes...
+[open-ephys] Got HS part #: NPM_HSTC_ext     <-- Do we ignore this part #?
+[open-ephys] Got HS part #: NPM_HS_32
+[open-ephys]       Found 2.0 Phase 2C dual-dock headstage on port: 1
+[open-ephys]   No headstage detected on port: 3
+[open-ephys]   No headstage detected on port: 4
+[open-ephys]    Found probe part number: NP2020
+[open-ephys]    Found probe serial number: 22053112201
+
+On subsequent connections randomly getting either error code 8 OR 2.0 probe headstage number:
+
+[open-ephys] ***detectHeadstage failed w/ error code: 8
+[open-ephys] Got HS part #: NPM_HS_01
+
+
+
+

+
+Downgrading QBSC firmware back to .189 no longer gives wrong HS PN but rarely still getting error 8.
+
+Created Ph2C Geometry based off NP2 multi shank class and Ph2C User Manual to validate probe. 
+
+Added a loop to read packets by base / source type 384 channels at a time to fill a 384 * 4 total buffer.
+
+TOFIX: 
+
+
+
+Changes required for compatibility with current plugin paradigm
+
+1. Upgrade PortChecker b/c ports are no longer independent and connecting to multiple Ph2C probes this way will not work. 
+We either have to scan ports serially and check that NPM_HS_32 is on port 1 or 3, if so, ensure that NPM_HSTC_ext is found on 3 or 4 respectively.
+Otherwise, keep the parallel jobs but then validate port indeces before initiating connection to probes.
+
+2. Modify basestation view in plugin editor. 
+If NP2020 detected on port 1/3, show as dual dock and remove port circle on 2/4 respectively.
+
+Questions for Bill/Jan: 
+
+1. What to do about port 2/4 status LED, it currently remains red even if port 1/3 is connected/acquiring (see picture)
+    TODO: Try to open port 2/4 anyway and see if it changes the status LED.
