Hardware / Re: USBCOM big problem

Perfect thread for me to tag on to.
I have a gearmo FTDI FT232R - amazon usb rs232 with lights.
I followed the docs:
/sys/doc/usb/usbcom.txt - which then points to
/sys/doc/usb/usbser.txt - for type FT232R.
the docs specifically call out that the FT232R has not been tested.
I built up the correct DEVICE line in config.sys, and placed it at the bottom of the file.
Questions for you all.
Should the usb rs232 be plugged in when you boot, or can you plug it in after you boot, or does that matter?
I installed ZOC and hooked up a loopback plug.
TX/RX do not seem to change state, but I see other lights, installing ZOC and setting to the correct com port Zoc thinks it's sending and receiving and I see stuff on screen.
Next test is to hook it to another computer with an RS232.
Last question, where can I find lsusb?
I queried the ANPM and it said NADA.
Thanks,
Dan
