 Hi again,
 
 I've done some additional debugging till now.
 
 The problem is not sensitive to the size of the first transfer chunk as 
 mentioned before - so PR 46696 seems to describe the a different problem.
 
 What happens?
 
 When a new device is found in usb_subr.c a transfer is done and only 8 
 bytes are expected back.
 After that the address for the new device is set on the device and then 
 the whole description structure is retrieved again.
 After that the default-pipe is killed and reopened again.
 
 Now when getting the description again, the transfer gets STALLED - the 
 first status seen by the system. (STALLED is returned.)
 
 In 5.x there was a different order: first get the description and than 
 set the address and then kill pipe etc.
 If I change it back to this order, I get some data back (18 bytes as 
 acpected) but the transfer still gets STALLED and now IOERROR is 
 returned. This looks much better but still does not work - perhaps some 
 settings related to the 64 bytes instead of the 8 used in 5.x may be the 
 reason.
 
 I'm not realy confimed with the order of actions on the USB bus, but it 
 looks wrong to me to change the address but reuse the old pipe for the 
 description prior destroy/reopen of the pipe.
 
 I hope some one has the time to look at this, because this problem stops 
 me from upgrading to 6.x, because I need the old USB devices ...
 
 best regards
 W. Stukenbrock
