Hi!
I've got a question for the hardware specialists here.
When running the command "dmesg" in the console, I found out that there are 2 USB ports detected.
-----
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 2 ports detected
-----
I think about to do a hardware hack and add one USB port to the board.
Need information if this would be possible.
Thank you!
I was able to add to serial ports using an external USB port, an external hub and two PL2303 based USB/Serial port adapters under dd-wrt. I had to install two kernel modules manually.
insmod usbserial
insmod pl2303
The serial ports show up in dmesg as USB0 and USB1, however, the actual device file names are:
/dev/usb/tts/0
/dev/usb/tts/1
I added a script in /jffs/etc/config called begin.startup, which loads the modules on reboot. (There may be a better way do do this.) Files in /jffs/etc/config with the extension .startup are executed on boot up.
Note - you can add a serial port using the internal connector and the instructions are listed somewhere on this site. The RS-232 voltages are 3.3V. The chips from MAXIM operate with specific voltages. So if you go this route - make sure you get the right version.
Hi!
I would rather like to use a 2nd USB device, no serial (RS-232) device. I am running successful a USB-Harddsik and would like to add another one, or a flash drive. Do you if I only need to solder a connector in it, or isn't it that easy?
May be it is the serial connector, which is used to debrick the router?
