I just wonder why I can no longer use device mode only after I plug in the 
adaptor for host device. Before that, I can plug in the device mode cable from 
PC all I want and this works. Then I plug in the host adaptor, that works as 
well , but if I plug in the device cable, this works no longer.

I rather suspect it might be something going on in the driver that's not right. 
I will check the hardware too, thanks.

Best regards,
Marek Vasut
