Hey, I would like to let you know that we have already involved our Development in this case and they are currently working on the resolution.
Same problem. when I click on an a device in the "External Devices" panel it disappears. I have to quit Parallels and then reboot the MAC, restart Parallels then they re-appear. Have also tried suggesed fixed without success. Paralles 11 MAC El Capitan 11.2.
is there an update regarding that issue?
Hi Martin, please disconnect the USB device from Mac physically and reconnect it back. The device will become available in the virtual machine.
To return device connectivity back to the Mac OS, disconnect it from the virtual machine via the Devices menu -> External Devices and check how it works.

Please refer to this article which addresses the workaround for now.
Your workaround doesn't work if your using the Apple Internal Card Reader. When I first view the USB devices PD shows "Apple Internal Memory Card Reader.
When I install my card it changes to Apple SD Card Reader (Disk 1).
I than select it and I get the error, Unable to connect.
This has been happening since the Apple Update. Before the update my reader never said Apple SD Card Reader (Disk 1). It was always Apple Internal Card Reader.
