ZyDAS the wireless on usb problem

Hi there,
I've got a really messy problem that I'm fighting with it for a couple of days. The uncle google don't know the answer to my problem or it's hiding it very deep :/. Lets go straight to the problem. I've got a wireless card on usb. There is written a UNICORN on it and I'm sure that it's on zydas chip because I've got a cd with drivers. I've successfully installed drivers from that cd but I cannot get this wireless to work. And I cannot figure out what to do. I am a newbie to linux but I'm learning hard that's the way I chose Slackware. I know that this description is not so good so here is some stuff:

form dmesg after turning on the module by modprobe zd1211:
usb-uhci.c: $Revision: 1.275 $ time 02:01:41 Sep 1 2006
usb-uhci.c: High bandwich mode enabled
usb-uhci.c: v1.275:USB Universal Host Controller Interface driver
# big zydas :) letters
zd1211 - version

usb.c: registred new driver zd1211
when I unplug and plug again wireless card i got in dmesg:
usb.c: USB disconnected on device 00::12.0-1 address 2
hub.c: new USB device 00:12.0-1, assigned address 3
usb.c: USB device 3 (vend/prod 0xace/0x1215) is not claimed by any active driver
At this point I think that the problem is that it cannot bind my device with the driver and I have no clue how to do that or where to find it.

by lsmod i get:
Module		Size	Used by	Not tainted
zd1211		266048	0	(unused)
usb-ohci	18856	0	(unused)
usbcore		56812	1	[zd1211 usb-ohci]
tlan		27484	0	(unused)
ide-scsi	9392	0	
agpgart		45092	0	(unused)
and by lsusb:
Bus 001 Device 001: ID 0000:0000
Bus 001 Device 003: ID 0ace:1215 ZyDAS
ifconfig -a

Link encap:Ethernet

I didn't wrote all the messy code because this entries are to and my wired adapter.

lo no wireless extensions.
eth0 no wireless extensions.
And the last thing I've got Slackware 11 with 2.4.33 kernel. PII 200Hz and 32MB RAM. (yeah a dinosour )

This is all I can think that could be useful. Thanks for your solutions, pointing where to start looking or any help you can give me.

I'm using ubuntu too and there is no problem with my wireless. I just plug it and it works. But that is not the point. I want to make it run on Slackware because I'm going to use this distro. And my problem is on Slackware not ubuntu.

I didn't notice that the compilation of driver was with an error. This driver provides two modules the zd1211 and zs1211b. I don't have module ehci-hcd wich is probably for zd1211. I got only usb-ohci and for that i thought is the zd1211b where i got errors. So I figured that it was in source code. Two lines was commented out wich were defining variable before use.

These lines are in function HW_UpdateIntegrationValue:
3774: void *reg = pObj->reg;
3775: struct zd1205_private *macp = (struct zd1205_private *) g_dev->priv;

After the compilation and turning on module i can see by ifconfig my adapter witch is on eth1.

But after this I have another problem i cannot connect to my AP. I first turned every security just to test connection. so there is no wpa or any other auth. I set up the ip addres by ifconfig with netmask and route pointing to my router ip. The connection isn't established . I looked then that channel don't match the channel of my AP. So I had tried to use iwconfig eth1 channel 6 and i have an error:
Error for wireless request "Set Frequency" (8B04) :
  SET failed on device eth1 ; Invalid argument.
I had also try to set frequency by iwconfig ... freq 2.437G. It produces same error.
And by iwlist scan i have
eth1   No scan results
Can it be the driver fault? Or am I doing something wrong.
