Hi all, The USB midi port on my PX-350m seems to work only intermittently. I've tried various different USB ports, both 2.0 and 3.0. I've tried in Windows and Linux. I've tried every permutation of turning the piano on before my computer, computer before piano, plugging in the USB cable only after booting etc. etc. I've seen it work for definite in Linux twice so far. Both times in a USB3.0 slot. Once when I booted my computer with the piano turned on and plugged in, once when I turned the piano on after I had booted into my OS. Neither time required any additional drivers etc. (as makes sense, class compliant). It also registered itself correctly with Windows 8.1 once ("CASIO-USB-MIDI" or whatever the correct name is, showing up in device manager). These are only 3 out of maybe 20 times I've tried so far. My linux distro is Mint 17.1, my motherboard is an asus P8Z77-V PRO. Anyone experienced anything like this before? I'm not having any other USB issues with my computer so I'm inclined to believe it is the piano that is acting weirdly. Is there some specific voodoo that I need to perform before I try to connect? Thanks, - Kieran
