When my serial2usb adaptor is connected. And I look in /dev on my computer this is listed: cu.usbserial-FTKVMAFF But when I try to open my vm, I get an error: loctl failed for serial host device '/dev/cu.usbserial-FTKVMAFF' (VERR_DEV_IO_ERROR). The device will not work properly. And under details- Error ID:DrvHostSerialFail And when I look in /dev cu.usbserial-FTKVMAFF Is gone? And my settings for my vm are Ports-->Serial Ports-->Port 1--> Enable serial port, checked Port mode- host device Create pipe, unchecked Port/file path: /dev/cu.usbserial-FTKVMAFF > Ralf > > > ------------------------------------------------------------------------------ > Using storage to extend the benefits of virtualization and iSCSI > Virtualization increases hardware utilization and delivers a new level of > agility.
