Martes, > Thanks for the info.

Operation timed out "reset" is the very first command in the initialization sequence. since it has timed out then communication between host and adapter is broken (for whatever reason). after google'ing a bit i found out that this particular card 1. uses 16c950/954 uart, which is a good thing because it has 128 bytes fifo (compared to 16 bytes in 16c550a). you might want to try puc(4) driver that might have support for this uart. 2. apparently needs extra initialization sequence. that is you need to send extra vendor specific command to the adapter to setup uart speed. my guess item (2) above is the reason why you got timeout in "reset". basically i need to prepare a patch for hcseriald(8) and send it to you. it will take me a few days to do that. since i do not have the card here i will rely on you to help me with testing. in the mean time you might want to try item (1) above to see if puc(4) driver works and recognize 16c950/954 uart. if you feel like hacking it yourself, you might want to take a look as linux bluez hciattach utility (online cvs http://cvs.sourceforge.net/viewcvs.py/bluez/utils/tools/hciattach.c?rev=1.29&view=markup). this utility does a similar (to hciseriald(8)) job. if you get it working please send me the patches and i will review and commit them. > I also find it extremely difficult to get anywhere when things don't work.
