The zd1211 driver has a bug in the ieee80211 config callback. It currently unconditionally calls the set_channel() function, whether the device is running or not. This causes a failed bus access, if we set some config while the device is down. The driver must check if the device is running before setting any config on it (usb->initialized?). I tried to fix this, but I failed to find the correct condition to check for. I'm also wondering why we only set the channel in the config callback. Is the rest all unsupported by the device, like setting of TX power and so on? - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
