Re: [patch] workaround zd1201 interference problem

Hi!

quoted

Well, I'll try _enable() alone, but it seems to me that _enable()
command is needed to initialize radio properly. I do not think we can
get much further without firmware sources...

If you can formulate a proper and technical description of the issue 
(and exactly what is needed to workaround it), I can contact ZyDAS for 
you. They have been very helpful with ZD1211.

Okay, the issue is:

if you plug zd1201 into USB, it starts jamming radio,
immediately. Enable/disable, or iwlist wlan0 scan, or basically any
operation unjams the radio. This patch works it around:

diff --git a/drivers/net/wireless/zd1201.c b/drivers/net/wireless/zd1201.c
index 335eaf3..dcc7bc7 100644
--- a/drivers/net/wireless/zd1201.c
+++ b/drivers/net/wireless/zd1201.c

@@ -1835,8 +1835,8 @@ static int zd1201_probe(struct usb_inter

 err_net:

....question is "is that right solution, or is something different
needed to solve that problem properly"?
