When i first installed official drivers, my POD HD 300 was detected as usual. No alert.
BUT when i started Monkey ... nothing.
Same with Licence Manager and Edit.
When i started Windows 10 x64 diagnostic (right click), Windows showed a message alert telling me POD HD 300 is USB 2.0 only could NOT be plugged on an USB 3.0 port
WHY Windows didn't told me BEFORE ? :D
Changed plug on an old USB 2.0 hub : no more problem
If it can help someone ...
