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.
Looks like you haven't loaded a usb host controller driver for your
hardware. Are you sure you have such a thing loaded and working? Does
other types of USB devices work when plugged into this machine?
You really are on your own here, sorry.

I found host controller drivers in menuconfig and compiled them and inserted
with insmod and again nothing happened.I tried with usb flash but nothing
happened. I send you log for this. You will see in the log
those drivers that I loaded (there is compliant about kernel version
but insmod command passed and the modules are in /sys/module directory)
and I didn't see anything related to usb converter and mass storage.
The host controller drivers I loaded are : isp116x-hcd.ko, isp1760.ko,
oxu210hp-hcd.ko, sl811-hcd.ko.
That's it.
Milutin.
isp1362_hcd: version magic '2.6.35.7+-androidarmv6 preempt mod_unload ARMv6 ' should be '2.6.35.7-androidarmv6+ preempt mod_unload ARMv6 '
<4>[66113.287000] isp1362_hcd: Unknown symbol bitmap_find_next_zero_area (err 0)
This means that the driver really didn't get loaded, so there's no way
any USB devices could work on your system.
Try fixing that up first...
I fixed it and pl2303.ko and isp1362-hcd.ko loaded and registered without
any errors and then pluged the converter and I think nothing happened
sending you a log.
Best regards,
Milutin Aksic.
If the host driver doesn't bind to the device and start up (you should
see some log messages about finding a root hub) then no device will ever
be found.
sorry,

Ok, then what I should try else what can be the problem why host driver
doesn't bind to the device? Maybe the phone gt-s5570 doesn't have
any hardware (but I doubt it is the truth) or something else.
Thanks Greg anyway,
Milutin.
