How to access USB device if booted with Windows 7 64-Bit Recovery Disc

[clgfsc]

Hi all!
I just bought the Windows 7 64-Bit Recovery Disc and the and my PC boots from it as expected, but what a shame, I can not access a USB memory stick attached to it.
I actually expected this to work as it does on an other PC, but with 32 Bit OS. what do I have to do to get this access?

Please find below some information about my PC (sorry, it's in German, but I think you'll get it anyway):

Whether or not the WinPE environment of our repair CD has USB support is based mainly on your BIOS and what type of USB support it has.

Thanks for your reply!
Is there a chance to get access by loading some driver after the PC has booted up?

 

[mqudsi]

Perhaps. You'd have to contact your motherboard manufacturer for the USB chipset drivers.
