Getting my new OpenPCD working

[Power, Mike]

A quick update:

 

I can load modules by hand while specifying the vendor and product.  I
still have not figured out why udev does not load the module, I still do
not understand how it works in general.  Of course it might be a problem
out side udev.  

 

Two things that are particularly interesting.

I can run

sudo insmod
/lib/modules/2.6.24-19-server/kernel/drivers/usb/serial/usbserial.ko
vendor=0x16c0 product=0x076b 

 

and then I get this output in my syslog:

b_0'). 

 

Just a guess it seems to try to use the generic driver instead of the
ftdi_sio and fails with -5.  Is that bad?

But regardless I get a ttyUSB device

mpower at mtvd04a119587:~/temp$ ls -l /dev/ttyU*

crw-rw---- 1 root dialout 188, 0 2008-07-11 11:26 /dev/ttyUSB0

 

But now opcd_test doesn't even work:

mpower at mtvd04a119587:~/workspace/OpenPCD/host$ ./opcd_test -n opcd_test
- OpenPCD Test and Debug Program

Unable to claim usb interface 1 of device: could not claim interface 0:
Device or resource busy

 

I can also reset and run

mpower at mtvd04a119587:~/workspace/OpenPCD/host$ sudo insmod
/lib/modules/2.6.24-19-server/kernel/drivers/usb/serial/ftdi_sio.ko
vendor=0x16c0 product=0x076b 

 

Then my syslog has:

Jul 11 11:38:23 mtvd04a119587 kernel: [ 7218.095084]

Still getting the -5 error and more importantly no device:

mpower at mtvd04a119587:~/workspace/OpenPCD/host$ ls /dev/ttyU*

ls: cannot access /dev/ttyU*: No such file or directory

 

but opcd_test works:

 

mpower at mtvd04a119587:~/workspace/OpenPCD/host$ ./opcd_test -n opcd_test
- OpenPCD Test and Debug Program

(C) 2006 by Harald Welte <laforge at gnumonks.org>

 

TX: (8):  03 01 00 01 00 00 00 00

SERIAL: (4):  2d 74 a0 53

 

At this point I am at a loss of what to do next.  The device works on my
XP machine, so it seems like it is a Linux configuration problem.
