I've been trying to get a tmote sky (http://www.moteiv.com/products-tmotesky.php) working with FreeBSD. This device uses an FT232BM chip and speaks a custom protocol to program a TI MSP430 chip (using a python program, pybsl, from http://mspgcc.sourceforge.net/tools.html). The device shows up as: ucom0: Moteiv tmote sky, rev 2.00/4.00, addr 2 and I get /dev/ttyU0 and /dev/cuaU0 as expected (I'm running 6.1-PRERELEASE). pybsl initially attempts to connect at 9600 baud. At this speed it would make some progress and then fall over. I found that if I lowered the speed to 2400 baud and inserted a couple sleep calls into the script it could program the device. However, at 9600 baud it never worked. I would love to get this thing fully working. I have no problems programming this exact same device under Linux or Windows, so the device itself does not seem to be the problem--there's clearly something weird going on with the uftdi driver, but I don't know where to start. I'm happy to hack on this, I just need someone to point me in the right direction :) Thanks, Geoff
