I needed a MSP430f1610 with USB.
I followed the schematics in the application note, but I can't figure
out the software. It looks like there are so many ways to do it, and I
can't find one that works.
The first problem I have is trying to figure out the baud rate on the
serial side. I do not see any examples of setting it. I would have
thought it would be one of the EEPROM parameters, but it is not.
I took the code out of the applications note and it would not work out
of the box, it hung trying to determine if there was an EEPROM.
So I started looking for the technique for loading from the USB side.
The applications notes reference each other and none of them tell you
how to do it from A to Z, because they talk about the TUSB3210,
TUSB3410, TUSB5052, and TUSB6250. I guess they just assume you can
connect all of the dots. And they reference some code that is not easy
to find on TI's web site. (It took a while, but finally found it. One
would think to search for the code name in the TI document would do it,
but it didn't.)
Even though the board is working except for the USB, I am thinking of
redoing it with a simpler chip that is easier. My Linux friend is
recommending a PL-2303 as it is well supported with Linux and "just
works".
We loaded the TUSB3410 Linux drivers, and it tells if it is plugged in
or not, but does not make connection.
Has anyone outside of TI got this to work?
I have spent 2 weeks on it and am nowhere, and I normally do not get
stuck. The fall back plan is to hack a USB to serial cable for this
version of the prototype, and rip the USB chip off the board.

Anyone with success with TUSB3410 interfacing to MSP430?

How did it hang? Swinging to the left and right or just stayed still?

Here is the code from the TI demo software:
unsigned char EEPROM_CheckNACK(void)
{
while (I2CDCTL & I2CBUSY); // Wait for I2C module
U0CTL &= ~I2CEN;
I2CTCTL |= I2CRM; // Disable repeat mode
U0CTL |= I2CEN;
U0CTL |= MST; // I2C master mode
I2CTCTL |= I2CTRX; // Transmit mode (R/W
bit = 0)
I2CIFG &= ~NACKIFG; // Clear interrupt flag
I2CTCTL |= I2CSTT; // Send slave address
// It hangs on the next line
while (I2CTCTL & I2CSTT); // Start condition
I2CTCTL |= I2CSTP; // Stop condition
while (I2CDCTL & I2CBUSY); // Wait until finished
U0CTL &= ~I2CEN;
I2CTCTL &= ~I2CRM; // Enable repeat mode
U0CTL |= I2CEN;

These drivers are not compatible with WinCE or WinXP-Embedded.
Beta Linux drivers are also available from our third party Brimson Labs
(www.brimson.com) for the following kernels:
* Linux kernel 2.4 (beta)
* Linux kernel 2.6.9 (beta)
Now I have to find out if the Nokia 770 runs 2.4 or 2.6. Their release
notes say 2.4 will not download the software if no EEPROM is present,
2.6 will.

I opened up a Q-Stor USB to Serial adapter. I was able to cut the molded
part with box cutters, and the inside was potted. I carved the potting
until I hit the edge of the board. Then I was able to pry the potting
off the top and bottom of the board. They were nice enough to wrap the
board in masking tape prior to potting so the potting came off easily.
After unwrapping the masking tape, I had a relatively clean little
board. And it still works.
The USB connector from the Nokia 770 does not supply 5V, it expects 5V
so I have to add a 5V regulator, but this may work for now. I normally
have only 3.3V on the board.

Which drivers are you using under XP? (I will start there then move to

This is what I am looking for.
I may have the same problem. What is the input pin?
