Win7 - USB storage problem

[jazzalex]

Hello all,

I am running Virtual Box on a Mac OSX host (10.9.2) with a Win7 client. Guest installations and extensions are all installed and work perfectly fine. However, one final problem remains:

Whenever I try to access a USB storage device (external HDD or USB stick) with the Windows client it does recognize the hardware but the device is not accessible. Win7 itself does not indicate any issues but when observing the device in the hardware manager it tells that the device cannot be launched (see screenshot).

I really do not know how to fix this issue so any help is highly appreciated.

Thanks in advance,
best

Alex
