--- Comment #1 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
Hi,

Some ideas:

Have a look at the USB traffic using usbdump tool. It will show what is goi=
ng
on at the lowest level.

Are you using libftdi?

Are there any other applications which use libusb to communicate with the F=
TDI
chip instead of /dev/cuaUX ?
