Re: timeout in zd1211rw with zotac mini-itx (geforce 9300)

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.

firmware doesn't load? but files are there?

Fedora Core 12, Linux 2.6.32.11-99.fc12.x86_64 #1 SMP Mon Apr 5
19:59:38 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

The firmware files seem to be there -- and they cmp fine with the v4.1
firmware files from sourceforge.

$ ll /lib/firmware/zd1211/

This is after bootup...

Error -110 is USB timeout. it is just an indication that the device is not responding - not enough power from
the motherboard and is a hardware rather than a software problem, is probably my guess, given recent
problem reports.
