-Touchscreen hangs on first boot, have to power off and on the screen to make it working
-Also is impossible to disable ADB, strange behaviour with Developer Setting menu too (adb can be disabled only with Developer Setting ON, if i select OFF, adb auto-re-enable it self when USB is connected again)
-mouse cursor with USB Host is really SLOW and LAGGY
-on USB Host disconnect, "Select method od writing" doesn't disappear, if i select HTC Sense Input it's still there, cannot remove from the notification bar
-MTP it's FUUUUU**** SLOW!!! Bugged, cannot copy flac file!!! When first file is copied, than it stop copying!!! This ruined my day, tomorrow i have no music on my phone!!! FU** HTC!!!
New feature! USB Host now is self powered! USB mass storage is working without external power!!!
-USB connection is changed
Pro: no data corruption, now ADB/Fastboot is working ok with Win8 Computer with Intel USB 3.0 too
Con: we are force to use htc sync manager, and MTP to copy files, TOO BAD
