some quirk issue around uhid operations

Tue Nov 17 02:08:34 UTC 2009

Hi USB developers :)

Our company's developer Ozawa-san has found some quirk issue
around uhid device operations.

For example, using uhid0 from processA and using uhid1 from 
processB at the same time, sometimes read(2) operation leads 
handup. In case useing those not at same time, there is no 
hangup. In this week he has been doing test and above issue 
happens all the time.

At last he didn't find does which read(2) or write(2) 
operations have a bug.  If you have some ideas or can resolve
this issue, please help us!
