USB Device Redirection | Change Access For Mount

[Stefanie Leisestreichler]

Hi.
I am using kvm/qemu to redirect my mobile phone in a Virtual Machine 
(via virt-viewer). The mount works automatically but unfortunately the 
permission to access the files (i.e. photos) is limited to the mounting 
user only. I want to grant access to other users also.

How can I archive this?

Thanks,
Steffi
