+COMPATIBILITY fixes:
+
+1. COMPATIBILITY: dual-mode devices, i.e. devices exposing both an MTP
+  and a USB Mass Storage Device Class (flashdrive) interface are and
+  have always been problematic. We must find a way to get this to work,
+  eventually. The problem is that the in-kernel mass storage driver hogs
+  the device before the MTP mode gets a chance of being used, whereas
+  the Windows kernel driver apparently does it the other way around, 
+  trying the MTP mode first and then not fall back on mass storage if
+  MTP is available. (For some more explanations se src/libusb-glue.h.)
+  This may involve kernel modifications.
+
+2. COMPATIBILITY: several devices tend to "hang" after disconnect, 
+  needing to be unplugged and replugged before they can be used again. 
+  We don't know why, it may be related to low-level USB behaviour that
+  is not exposed in the logs we read.
