minicom freebsd 8.0

[akash kumar]

Hi,

Finally worked for me. Thanks all for your help.
Below are the steps.

1. /var/log/messages has below message when ever usb port is inserted. 
> Unknown USB device: vendor 0x4348 product* 0x5523* bus uhub2 

2. grepping for vendor no. 
> grep 0x4348 /usr/src/sys/dev/usb/* 
/usr/src/sys/dev/usb/usbdevs:vendor WCH        0x4348    QinHeng Electronics 

> cat /usr/src/sys/dev/usb/usbdevs | grep WCH 
vendor WCH        0x4348    QinHeng Electronics 
/* WCH products */ 
product WCH CH341SER        *0x5523 *   CH341/CH340 USB-Serial Bridge 
product WCH2 CH341SER        0x7523    CH341/CH340 USB-Serial Bridge 


3. After bit of googling with 'CH341/CH340 USB-Serial Bridge', found that specific module is missing.
  Added uchcom in to the config file and rebuilt the kernel and booted 
with it. 
> kldstat -v | grep uchcom 
       309 uhub/uchcom 

4. After rebooting could see below messages i.e device being recognized 
as the module is already present 
ugen2.3: <vendor 0x4348> at usbus2 
ucom0: <vendor 0x4348 USB-SER!, rev 1.10/2.50, addr 3> on usbus2 
ucom0: CH340 detected 

The device is created with name  /dev/cuaU0 and it worked finally with minicom. 


Thanks,
Akash.

Ah, okay. ugen is a generic device. I think you can't use that directly
if you have a usb-to-serial converter.

I guess you need to kldload a kernel module specific to your usb-to-serial
converter. For example something like uplcom, umodem etc. This would
create a new entry in /dev that you can use in minicom.

Permissions for those devices can be set in /etc/devfs.rules (and restarting
devfs with /etc/rc.d/devfs restart). You may also want to look at /etc/devd.conf

I'm not familiar with usb-to-serial converters, so I can't help more than that.
Others may have more experience there.
