zd1201 & ipw2200 problems

zd1201 & ipw2200 problems

[Pavel Machek]

Hi!

I see some strange problems with zd1201. (Ccing greg, he seen
something similar).

Wireless LAN is configured on eth1 (ipw2200) and works. I insert
zd1201 usb wireless card, and pings stop. I do not have (or should not
have) any hotplug scripts doing anything. Leds on zd1201 light up.

If I unplug zd1201, pings immediately continue.

If I issue iwlist wlan0 scan, zd1201 discovers some networks, its led
goes out, and ipw2200 ping immediately continue (ipw2200 starts to
work).

Now... what is going on? Any ideas how to debug it?

Plus, zd1201 does not work on sharp zaurus (pxa arm-based)
machine. (Any idea if that is little or big endian?). It is detected
okay, lights light up, but iwlist wlan0 scan produces no results.

In-tree one, 2.6.17-rc4 (and around). Ouch and I've "solved" the
zaurus problme in the meantime -- it was hw one.

Oops, sorry, I was thinking of the zd1211 driver, which is still not in
the kernel tree and there are a few different versions floating around.

Glad it's working for you now.
