The Midi 2 CV is class-compliant but uses an unusual USB setting (1ms poll-rate in low-speed mode) not well supported on Windows.
Optimal latency is obtained with OS X >= 10.6.3 ; iOS ; or Linux >= 2.6.
On other systems, the Midi 2 CV will work but messages will be delayed by up to 8ms.
Range and standards:
USB-bus powered, current draw < 20mA.
