I wish to create an usb driver for my Ericsson cell phone on my production
machine. As this is a production machine I am loath to start changing kernel,
especiall to a test kernel therefore I wish to stay with 2.4.20
Following on from Greg KH <[EMAIL PROTECTED]> articles in the Feb/April 2003 Linux
Journal I have attempted writing my own driver but as you can well imagine I
have had a problem or two. His environment is Kernel 2.5 or greater and mine is
2.4.20.
When I compile I get
[EMAIL PROTECTED]:/usr/src/linux-2.4.20/drivers/usb/serial# make -C

Is there any way of my staying with 2.4.20 and still get this program working?
I also attach my version of his tiny tiny usb serial driver in case that makes
a difference.
I have also noticed that in usbserial.c usb_serial_probe and
usb_serial_disconnect are defined as static.
Is this part of my problem? As far as I am aware static functions are only
useable from within the module where they are defined.
Look forward to your reply as I would really like to get this working.
BTW When I plug my device into the USB port I get:-
Aug 19 15:09:11 puppypad /etc/hotplug/usb.agent: ... no modules for USB product
731/528/1
and I have assumed that 731 is the PRODUCT_ID & 528 is the DEVICE_ID?
in hex that would be 0x02db and 0x0210 respectively.
