I'm using XP via VMWare on a 5K iMac.  The Autel software only looks for a USB input and the new iMac's SD card slot now uses PCIe, so I copied the SD card to a MicroSD card and used a USB adapter.  (yes, the MD802 works fine this way using a microSD to SD adapter.) The update  program sees the card and changes to E:\, but when I select update it still says to connect the SD card to the USB port.  Any suggestions (I don't have any Windows machines)
