Today i got hold of galaxy note. I had managed to compile stock kernel for the same along with the usb drivers, though i compiled rtl8187, rtl8192cu,ar9271,rt2800usb while testing some of them caused problems and rebooted device. rtl8192cu and ar9271 were the bad boys, so i had to remove them. rt2800usb works perfect( tested with two cards one asus and buffalo). and with rtl8187 also had problems, i used a alfa device i think the problem was power form the device is low so i pulled out a usb cable for the external usb hard disk which had an additional usb plug which can be connected to a pc to draw power. when i used that cable rtl8187 strted working.
