 Hi,
 
 There are some debug parameters under:
 
 sysctl hw.usb.timings
 
 Which might affect the behavior of your device. Make sure you have the 
 XHCI patch for 9.2-RC1 which was in a big late, if you compiled the code 
 yourself.

 Could you show the dmesg about which USB controller is at usbus0 in the 
 non-working case?
