T110's boot manager doesn't find all usb sticks

Hi

I have 2 usb sticks:

#1: Sandisk Ultra - 32GB
#2: Sandisk Cruzer Blade 8GB

When I go to boot mananger -> Boot settings -> Set legacy harddisk drive order, the T110 only finds stick #1 and not #2.
I have rebooted and switched sticks, a couple of times

Both sticks works fine in windows vista.
What do I need to do to make my Poweredge find the Cruzer?


Thanks /
