Some more diagnostic info for the rw driver, this time compiled as
built-in and debug option in the kernel for 2.6.30.

dmesg for rw driver output:

I have downloaded the vendor driver and applied your patchset.

Inserted the vendor  { USB_DEVICE(0x0411, 0x00DA) }, in
ar2524drv/src/zdusb.c

Recompiled as zd1211REV_B
