Apple SD card Reader can't be read

[lecciovich95]

Hi, I was trying to read my 128 gb SD card on my Mac Pro Retina whit OSX Sierra and I didn't understood why can't be read as I can do with USB devices. Virtualbox settings are in the USB part setted with Apple Internal Card Memory Reader added on Usb devices filter when I insert the SD card in the SD slot I can see device in OSX but not in Linux VM and if I try to import the Apple Internal Card Memory Reader from the menu Devices in the sidebar there is this error: Failed to attach the USB device Apple Internal Memory Card Reader [0820] to the virtual machine Debian.

USB device 'Apple Internal Memory Card Reader' with UUID {0188dbba-4e3b-4cba-aab4-77f3145f8267} is busy with a previous request. Please try again later.

Result Code: NS_ERROR_INVALID_ARG (0x80070057) Component: HostUSBDeviceWrap Interface: IHostUSBDevice {c19073dd-cc7b-431b-98b2-951fda8eab89} Callee: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I tryed to unmount di SD card from OSX and to add from sidebar the same device but the Mac told me the Volume is not unmounted correctly and however still not be read. so... what I have to do?

It's usually better and faster, if problems like this one (configuration, question) get first addressed in the forums (​https://forums.virtualbox.org/). More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

So, if you can, please open a new thread in the ​VirtualBox on Mac OS X Hosts section of the forums. Be sure to say that you came from the bugtracker and include the ticket #.
