[SOLVED]FTDI Issues.

Hi all, Im trying to get an FTDI usb controller working.

Dmesg shows that the driver is auto loading:

usb 8-2: new full speed USB device using uhci_hcd and address 9
ftdi_sio 8-2:1.0: FTDI USB Serial Device converter detected
usb 8-2: Detected FT232RL
usb 8-2: Number of endpoints 2
usb 8-2: Endpoint 1 MaxPacketSize 64
usb 8-2: Endpoint 2 MaxPacketSize 64
usb 8-2: Setting MaxPacketSize 64
usb 8-2: FTDI USB Serial Device converter now attached to ttyUSB1

I have a pl2023 serial adapter running a 1-wire network, as well as usb transceiver which I believe uses an ftdi chip?

the ftdi driver doesnt seem to work the relays (echo -e '\xff\x01\x01' > /dev/ttyUSB1) does nothing. (it all works great on a 9.04 ubuntu 2.6.28 install)

I need a push in the right direction, a log file I can look at? some irq settings?

thanks!

silly question - did you set the baud rate before trying to echo to the port? (man stty)

i didn't quite understand what the prolific chip and the other ftdi are doing. are you sure you are writing to the right device?

Thanks for the hasty response!

The prolific chip is running a 1-wire network (likely unrelated, but it is using the usbserial also)
the other ftdi I (think) is my IR transceiver.

I didnt check the Baud Rate! was very curious about that, as well as IRQ settings? Ill be combing through that man page!! will post results.

cheers
