Hello Greg,
I supose that serial communication should work with this older model
gt-s5570. I found custom rom with that old kernel version but I don't
know how to find newer version for this phone.
When I plug the converter to phone I can't see anything in the log that
is related to converter but I send you the log as attachment. It is log
when I insmod pl2303.ko via adb and after that pluged the converter.
Bye.
Milutin.
