[gentoo-user] usb-> seriial(minicom) problem

[James]

Hello,

I have (2) different usb->serial converters, both of
 which are listed
when I build the drivers->usb->serial-converter in  a 
2.6.17-r8  kernel:

 USB Serial Converter support 
  USB Generic Serial Driver 
   USB FTDI Single Port Serial Driver (EXPERIMENTAL)
   USB HP4x Calculators support
 USB Xircom / Entregra Single Port Serial Driver

 here I show everything selected in this section>

so I build a new kernel
make && make modules_install
and boot off the new kernel.  All looks find from the 
subsequent
dmesg(snipped for brevity)
usbcore: registered new driver usb-storage
input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical

Bus 003 Device 001: ID 0000:0000
Bus 002 Device 003: ID 1645:8003 Entrega [hex]
Bus 002 Device 002: ID 0403:6001 Future Technology Devices 
International, Ltd 8-bit FIFO
Bus 002 Device 001: ID 0000:0000


So it all looks fine. Next I configure minicom...
I have mincom working on regular 9pin serial ports on multiple
systems. I know my cabling, and 8N1, 9600 baud and no hard/soft
FC work to the serial port on the test (cisco) device.
 So I know that minicom is installed and the 
etc/minicom/minirc.dfl  match with system that work.

So my best guess the problem is the port device driver,
converter device or the port setting in /etc/mincom/minirc.dfl
I've tried all of these with the ftdi device:

pr port             /dev/ttyUSB0
pr port             /dev/bus/usb/002
pr port             /dev/bus/usb/002/002

Any suggestions are most welcome.  
The Entrega device was not plugged in during the reboot
so it does not show up in dmesg. The Entrega device
is the other device I have, but all attempts with it
fail also....I did notice the device has the name
Entrega printed on it and the kernel uses the name
Entregra, but, I was hoping they're the same?

ideas?

James

I see this (I have a pegasys based usb-232): 

Oct  9 08:42:46 orpheus usb 3-2: pl2303 converter now attached to ttyUSB0

and you see this:

> usb 2-1: FTDI USB Serial Device converter now attached to ttyUSB0

which is strange cause I also see /dev/ttyUSB0...

> pr port             /dev/bus/usb/002/002

did you actually manually check for the device /dev/ttyUSB0?

apart from that, I'm not sure what could be wrong...

Hello Ian,

Yes

Well, I did major surgery on a new kernel for the USB
stuff. Not sure what fixed it but now it works. I have
most everthing statically compiled into the kernel for 
USB and it works.  The next time I build a kernel for
this machine, I'll try and make it loadable.

I'm going to be adding a second device, so I can use the
portable to sniff all sorts of legacy(proprietary)
RS232 protocols.........
