Hi all,
For the single zImage demo @ Connect, our tentative plan is to have multiple boards connected to a single host so we can just have one monitor displaying multiple console sessions and then run 'uname -a' to show that the kernels are the same (this will not win any awards for visual appeal). I don't want to spend a week trying to get a driver to work so looking for suggestions on specific brands of USB multi-port serial adapters that are known to 100% work with Linux. As in you've tried it, maybe own one (hey, how about your bring it with you?!), and it worked, not as in "I read on google that it should work" :).
Thanks, ~Deepak

Anything with a FTDI chip in it is good and a USB hub does the multi-port part. I've got one of these: http://www.dicksmith.co.nz/product/XH8290/dse-serial-usb-adaptor
that I'll bring.

That's my setup at home too. You definitely need to make sure you get the FTDI chip-set, and my experience is that most adaptors which don't specify the chipset have the Prolific ones - which has never worked for me, not even in the days when my job required I use Windows.

here we have this product which works fine and provide 8 ports in an integrated casing : http://www.vscom.de/647.htm (it's based on FTDI's FR2232C)
lsusb says : Bus 001 Device 007: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 "TetraHub" Bus 001 Device 010: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC Bus 001 Device 011: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC Bus 001 Device 012: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC Bus 001 Device 013: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC
and I assume other products with more or less ports are based on the same chipset http://www.vscom.de/1_1_09.htm
