Hi greg,
We have dumped CP2103 from Silicon Lab, thanks for you advise..
Now I got TUSB3410 from TI (USB-Serial Converter).
I have selected "USB inside Out Edgeport Serial Driver(TI devices)"
component while building my kernel version 2.4.32.
Also I set "CONFIG_USB_SERIAL_EDGEPORT_TI=y".
Also I am compiling io_ti.c and io_ti.h (I don't know if they exactly
support this device or not). As such I have added {
USB_DEVICE(USB_VENDOR_ID_ION_TUSB3410,
ION_DEVICE_ID_TI_EDGEPORT_1_TUSB3410) } to edgeport_1port_id_table [] in
io_ti.c file, to handle Vend/Prod ID 0x451/0x341a for the device.
But still the device is not identified by the kernel when I plug it.
When Plugged, it says:
"USB HC dev free
May 11 06:03:14 crind30 user.warn kernel: USB HC dev free
USB HC dev alloc 1152 bytes
May 11 06:03:15 crind30 user.warn kernel: USB HC dev alloc 1152 bytes
hub.c: USB new device connect on bus1/1/2, assigned device number 5
May 11 06:03:15 crind30 user.info kernel: hub.c: USB new device connect
on bus1/
1/2, assigned device number 5
usb.c: USB device 5 (vend/prod 0x451/0x341a) is not claimed by any
active driver
.
May 11 06:03:15 crind30 user.debug kernel: usbserial.c: none matched
May 11 06:03:15 crind30 user.warn kernel: usb.c: USB device 5 (vend/prod
0x451/0
x341a) is not claimed by any active driver."
I think I missed some settings or I don't have working io_ti.c and
io_ti.h files for this device.
Please advise.
Thanks,
Prakash

Use a 2.6 kernel release with this driver included in it. Otherwise you
are going to have to backport the code yourself.
And I would not recommend using this device at all, the vendor will give
you a driver, but it violates the GPL, and as such, makes your version
of Linux unsupportable by anyone. And, if you redistribute the
resulting image, you too will violate the GPL.
In short, stay away from this manufacturer. There are many other good
usb to serial chips out there that work very well with linux.
good luck,
greg k-h
