mounting SD card on VM

[mans]

I am using VB on a windows 7 64 and guest OS is ubuntu 10.04.
I am not able to read/write SD card in Ubuntu and I am getting error that the device is buy and error code is:


Result Code:
E_INVALIDARG (0x80070057)
Component:
HostUSBDevice
Interface:
IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a}

How can I make it accessible in VB?

It would be safer to use a shared folder but if you must access it direct you would need to use RAW access. See user manual and be sure to read all warnings.

I need to access sd card as the guset host should format it with bot information and hence it needs complete access. Can you please give me the likc to which pat of manual explain this? I read the manual but could not find information on this subject.

I know this post is a little old but I found it at the top of the search results. Sadly it was of little help.

BUT...

I found the easiest way to directly work with SD cards on a virtual box machine is to use a USB card reader and pass the USB straight through. This is so much easier than trying to get the virtual machine to directly access a built in media card reader. That is unless your built in reader is detected as a USB device (some are).
