What SVN/P4 version did you test? Recently I have added a lot of sync code to 
help out on non-x86 processors.

What kind of processor are you using?

Could you do something like "sysctl hw.usb.debug=15" before you plug your 
memory sticks. Then afterwards "sysctl hw.usb.debug=0".

Post or send me the resulting debug output.

This error clearly indicates that something is wrong. wMaxPacketSize should 
never be zero with a few rare exceptions.
