USB to serial

[britnet]

Hi at all,

can somebody help me?

I want to runt open2300 with an usb-to-serial apadtor, but i get this in the log:


Oct 7 19:39:56 kernel: usb-uhci.c: ENXIO 40408380, flags 0, urb 8187e340, burb 8187e340
Oct 7 19:39:56 kernel: pl2303.c: pl2303_read_int_callback - usb_submit_urb failed with result -6
Oct 7 19:39:56 kernel:

when im calling fetch 2300.

I'm using this device: ttyUSB0 to read from

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

i get this in the log:

Oct 8 22:56:09 kernel: usb.c: registered new driver serial
Oct 8 22:56:09 kernel: usbserial.c: USB Serial support registered for Generic
Oct 8 22:56:09 kernel: usbserial.c: USB Serial Driver core v1.4

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

The problem is described in open wrt forum:

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?

[izo78]

Are you plugging it into USB-Hub?

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 :(.
