hi,
I have a Asus wl-500g DLX with OpenWRT RC5 installed. I bought a pl2303 based Serial to USB adapter to use with a rs232 smart card reader.
I installed all needed pkgs from ipkg repository. Here are the intersted modules loaded:

pl2303 12552 0
usbserial 23868 0 [pl2303]
usb-ohci 19204 0 (unused)
printer 9788 0 (unused)
usb-storage 65328 1
scsi_mod 70488 3 [usb-storage sg sd_mod]
uhci 30164 0 (unused)
usbcore 74792 1 [pl2303 usbserial usb-ohci printer usb-storage uhci]

Here's my lsusb

Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

Bus 001 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port


It seems to be seen correctly but when i try it to use with my reader my dmesg gives:
pl2303.c: pl2303_read_int_callback - usb_submit_urb failed with result -19

pl2303.c: pl2303_read_int_callback - usb_submit_urb failed with result -19

pl2303.c: pl2303_read_int_callback - usb_submit_urb failed with result -19

...etc...

...and the smart card reader soft gives me a Bind error: port already in use error. (tried with and withoput other usb devices plugged on the second port)

Tried with and without USB2..but always the same result.

Can anyuone help me?

Thanks and bye all.
Pino.

The pl2303 driver has been backported from 2.6.24.1 to 2.4.36.3. I got pl2303.c and pl2303.h from the latest 2.4 kernel (2.4.37.3), and I simply replaced the files in the kernel source with those. The resulting pl2303 module seems to work perfectly. The onlcr stty option works, and I can perform an interactive login via the port. I don't see any errors in dmesg output.

I'm using Oleg's firmware 1.9.2.7-10

Edit: You can download that module I compiled.

Take a look at 1.9.2.7-d firmware, based on Oleg's 1.9.2.7-10 with kernel 2.4.37.3, busybox, drivers, etc updated and improved
