Has anyone use the zd1211 usb adapter with mini-itx board based on geforce 9300? I have been experience some annoying issues ever since I got this motherboard. The problem is that sometime the card just cannot be switched on. It complains about ioread32() error -110. And I have spent a few days and try a few different combination, and here is what I have found so far: 1, with 1 wifi adapter directly plugged into the board, the wifi adapter works fine most of the time (have seen a couple failure, but is hard to reproduce) 2. with 1 wifi adapter, plugged in through a USB hub, the driver complains ioread32 error. I've try 2 USB hubs: a cheap 4-port USB dongle and also the USB hubs built into my DELL monitor. Both showed the same problem. 3. If I plugged in 2 wifi adapters directly to the board, more than 50% of chance one of the wifi adapter would fail during the 'ifconifg up'. I tried to dig our more on this. I am using kernel 2.6.24-26 (ubuntu). I had turned on the debug message output and I have traced out that the failure was first detected in the zd_mac_open(). Probably around the call to zd_chip_switch_radio_on(). The error message is printed in the zd_usb_ioread16v(), and probably indicate the driver is experiencing a timeout while it is trying to read the register from the adapter. What exactly does this mean? Why adding a usb hub cause such a huge differnce? Has anyone experienced similar problem before? Any pointer that can help me solve this problem is appreciated. BTW, I never had this problem before when I was still using a regular HP desktop PC, even with the same version of kernel and same USB hub. I switched to mini-itx because I am building a small system. So if anyone is currently using this adapter with a mini-ITX board, please also let me know which model you use. TIA, Tsuwei |

I am using kernel 2.6.24-26 (ubuntu). Please try a more recent kernel - 2.6.24 contains zd1211rw-ieee80211softmac, which is no longer developed. > I had turned on the debug message output and I have traced out that > the failure was first detected in the zd_mac_open().

I suspect it is just poor hardware. The more power-drawing devices you have got, the current/power available to each can drop, and some devices are more sensitive to drop in voltage than others. That seems to be the obvious conclusion - the more bus-powered devices plugged in, the more likely the wireless device fails to initialise. You probably would find that you will need a independently-powered hub (i.e. a USB hub which has its own power-plug that you need to plug into the mains) for it to work reliably, since your motherboard doesn't seem to be able to do it. --- On Fri, 16/4/10, Tsuwei Chen <ts...@gm...> wrote: > From: Tsuwei Chen <ts...@gm...> > Subject: [zd1211-devs] timeout in zd1211rw with zotac mini-itx (geforce 9300) > To: zd1...@li... > Cc: lin...@vg... > Date: Friday, 16 April, 2010, 21:34 > Has anyone use the zd1211 usb adapter > with mini-itx board based on > geforce 9300?

Gábor and Hin-Tak, Thanks for the quick reply. I thought about the current draw on the USB bus so I did try using the hub that is built into my dell monitor and had the same problem. I am going to try out the 2.6.32 today. I would report back the result once I got it. Also, some time I notice there is an 'address leak' with da_user=1. This happens when I unplugged the adapter. The systems seems still holding up well. Just wonder if this would be a concern.
