Hi beautiful people: I have just upgraded an iMac Mid 2010 running OS X 10.7 Server from Parallels 8 to 9. The Win7 x86 Boot Camp partition was mounting fine on Parallels 8 and everything was functional, but since the upgrade the "Human Interface Devices" category is constantly dropping one of the devices, then rediscovering it, only to drop it again straight away. The "offending" device IDs seems to be USB\VID_203A&PID_FFFB which a quick Google returns as pertaining the device "Virtual Keyboard". I have unplugged every external USB device (including the keyboard) but it makes no difference... the infinite loop carries on. Any suggestions beyond downgrading?
