    today i tried the ftdi driver described here: http://wl500g.info/showthread.php?t=608&highlight=FTDI

    i get this in the log:
    Code:
    Oct  8 22:56:09 kernel: usb.c: registered new driver serial

    Oct  8 22:56:31 kernel: ftdi_sio.c: v1.3.5:USB FTDI Serial Converters Driver
    this looks good, but how can i send/read data?

    I tried the fetch2300 command with the device ttyUSB0 but that doesnt work.

    I'm using this Adaptor: http://wl500g.info/showthread.php?t=5648

    There is a driver for it, can somebody compile it?

    I asked Oleg an oleo to make a driver for the wl500gp box.

    The Linux driver can be downloaded here:
    http://www.prolific.com.tw/eng/downloads.asp?ID=31 but this is not for MIPS

    Dongle usesProlific PL-2303 chipset which was reverse engineered. See:
    http://www.madingley.org/james/resources/pl2303/

    So:
    1. step -> i'll try the reverse engineered driver

    wl-500gp V2 & USB-Serial Adapter with pl2303 chip

    Does anybody know, if the combination (USB-Serial adapter with pl2303HX chip connected to wl-500gp V2 flashed with fw 1.9.2.7-10) is working well?

    I have tried with already plugged adapter

    1. to execute commands:
    insmod usbserial
    insmod pl2303

    syslog.log looks like:

    Jun 15 23:01:55 kernel: usb.c: registered new driver serial
    Jun 15 23:01:55 kernel: usbserial.c: USB Serial support registered for Generic
    Jun 15 23:01:55 kernel: usbserial.c: USB Serial Driver core v1.4
    Jun 15 23:02:00 kernel: usbserial.c: USB Serial support registered for PL-2303
    Jun 15 23:02:00 kernel: pl2303.c: Prolific PL2303 USB to serial adaptor driver v0.10.1


    and /dev/usb/tts/0 doesn't exists

    2. then replug adapter and then syslog.log looks like:

    Jun 15 23:09:09 kernel: hub.c: new USB device 00:03.1-1.2, assigned address 7
    Jun 15 23:09:09 kernel: usb.c: unable to get device descriptor (error=-32)
    Jun 15 23:09:09 kernel: hub.c: new USB device 00:03.1-1.2, assigned address 8
    Jun 15 23:09:09 kernel: usb.c: unable to get device descriptor (error=-32)


    and /dev/usb/tts/0 still doesn't exists

    What I'm doing wrong? Is the problem in pl2303 driver?

    Are you plugging it into USB-Hub?
    The God is real, unless declared as integer
    ipkg ( 08.06.11)

    No - I plugged it directly. I used the same combination with router WL-500gp (not V2) with the latest oleg fw and everything was OK, so I think the problem is in the driver implementation in V2 fw .
