USB developement

About a month ago I asked some questions on this list about USB driver  
development for the Neo. My conclusion was that the USB port had a  
problem because a lots of data was never reaching my receiver, and  
this was observed on the usbmon log data.

At first I thought that my receiver might have a problem and I stopped  
trying to implement the driver. But recently I tried a USB memory key  
on the Neo and it is not stable at all. When I'm copying files from  
the phone to the key and then I do a diff of the content of the key  
with the original files on my computer, sometimes they are not the same.

This problem was seen mostly when copying large files around 50 to 100  
MB. Moreover after a short while that the key is connected, it will  
stop responding and removing and inserting the key again will do  

So my question is that I'd like to know if the USB port on the Neo is  
a known problem and if someone else has experienced these glitches,  
and if yes, with what kind of hardware ?
