Re: Re: [Paparazzi-devel] difficulty installing u-center with wine

Hi Chris,

seems you are using the usb-tunnel 
(http://paparazzi.enac.fr/wiki/Compiling#USB_tunnel). This will appear as 
/dev/ttyACM0. Not sure if wine/u-center support that. FTDI chips will be at 
/dev/ttyUSB0.

You can use the Linux-only command line tool in conf/gps to configure your GPS 
receiver. Set the serial port and file name in ublox_conf.c, 'make' it and 
start it as './ublox_conf'.

A bit more digging; I've learned that installing the "wvdial" package (to set 
up a ppp connection with a GSM modem) probably introduced a kernel module 
called cdc-acm.ko. I think this is being used to mount my autopilot on 
/dev/ttyACM0 instead of /dev/ttyUSB0 or /dev/ttyS0.

According to comments in (linux source)/documentation/usb/usb-serial.txt, it's 
the usb-serial module that should be used to mount FTDI serial devices, cdc-acm 
is for some modems. Is there some way to get my machine to use the appropriate 
driver without removing the modem support (and losing my access to the 
internet).

Thanks Mark,

yes I tried that, but it also doesn't work - there is no such thing as 
/dev/ttyUSB0 on my machine. When I plug in the device I get a new /dev/ttyACM0.

Chris,According to the Wiki (http://paparazzi.enac.fr/wiki/GPS), you have to 
"set up com1 as /dev/ttyUSB0 See Info on wine for "dosdevices" setup."Did you 
do that?

Subject: [Paparazzi-devel] difficulty installing u-center with wine

Hi, I need to reconfigure my GPS but I am unable to install u-center (v5.08) on 
Linux (Debaan lenny) using Wine.

The error I get is during "Execute: DPInst.exe", after clicking through the 
"Device Driver Installation Wizard" screen, I get "Cannot complete device 
driver installation wizard; driver name: u-blox AG (ubloxusb) Ports (09/12/2008 
1.2.0.1); status: install failed ". I've tried it with and without my TWOG+GPS 
plugged into the USB (same result)

I think Wine might be OK because Motorcalc works fine under it.

I think I flashed my TWOG (+GPS :) with the tunnel OK, when I power it up then 
plug it in /var/log/messages has something like this:

Nov 24 21:44:12 dev-support-lappy kernel: [275135.220098] usb 1-1: new full

When I:

crw-rw---- 1 root dialout 166, 0 2009-11-24 21:44 /dev/ttyACM0

and:
dev-support-lappy:/home/daims# groups daims
daims dialout cdrom floppy audio www-data video plugdev netdev powerdev

so that looks fine. if I "cat /dev/ttyACM0" I get characters on stdout 
(non-assci). I don't know why it uses dialout group for that device, might have 
something to do with me installing wvdial a little while ago.

Oh yeah, I've also tried various combinations of linking com1 and com2 to 
/dev/ttyS0 and /dev/ttyACM0 in ~/.wine/dosdevices.

What should I try next? please help.
