Dear Diego and who concerns about this driver:
Thanks for reporting it. I can still provide some help, but it's just I'm quite busy.
So that you have not seem me sending patch for a long time.
I wrote this driver when I wan an intern in JMicron during one of my summer vacation
while I'm still student in 2008. And form that point, I do the maintenance just
for fun, not taking any money from them.
JMicron stopped contact me for a long time, and Diego told me that JMicron told him
this chip was EOL 6 years ago.
I have a confidential spec of this chip. I can still provide some help.
Diego is working closely with me for this issue right now.
