Re: X50v and IrDA

Hi, i'm also "working" on the port...
Working with "" because i don't know much about programming the linux
kernel and i don't know much about programming hardware :p (Also i
don't have much time to dedicate to it :( )
I have the x50v too, tried the kernels to boot but didn't get anything :(
I encourage to first get the usb connection, because it is the standard
connection you get when you buy the x50(v), this way all who have the
PDA and want to contribute will be able to do so.
