Hi,

The control request in question is mandatory according to the UMASS 
specification, and I wonder why it times out and all other control requests 
aswell.

Could you try setting the no-synchronize cache quirk instead, and then plug 
your device.

I'm sorry, but this problem needs further investigation before we can make a 
patch.
