The iTuner parts are firmware upgradable, so there is hope. The Picolcd.com SDK has code that does the flashing on Windows so it would be a matter of porting it, if firmware that addresses the issue becomes available. I have purchased a couple of these and they've worked with LCDproc CVS HEAD with the quirk. I just upgraded my testbed to CURRENT and will be producing the appropriate patch for the USB2 stack, later tonight.
