Hi,

I have a problem with USB WLAN (Belkn F5D7050 802.11g) and ndiswrapper: boot and hotplug does not work. Hotpug works partially - once.

At boot system when loopback device is started and wlan0 modprobed the system freezes. Unplugging WLAN stick boot continues. If I plug it in immediately again wlan0 is configured properly and network works fine. I can unplug and plug in the stick once after boot but next time causes ndiswrapper not to load anymore.

/sys/bus/usb/xx/yy shows correct driver after boot and one hotplug but after that the driver is missing.

/lib/modules/2.6.10y/modules.usbmap does not contain information about the USB stick and depmod -a does not create it.

Kernel is patched with 16k patch to avoid problems with windows driver. Kernel is 2.6.10. FC2 has been updated via up2date to the latest available packages and scripts.

One annoying thing was that I managed to get hotplug working by copying ndiswrapper from /lib/modules/<kernel>/misc to /lib/modules/<kernel>/extra but after updating it works only once.

What I haven't figured out yet is how usb.agent (hotplug) knows what driver needs to be loaded when WLAN stick is plugged in. Where exactly this information is stored?

I tried manually adding WLAN stick to modules.usbmap but that caused FATAL error at boot (no filesystem was mounted at that time). Same info has been tested in /etc/hotplug/usb.handmap and usb.usermap without any noticeable effect.

Hope someone can help me out here because I'm out of ideas (after several days of searching).

TIA


Snip of the log (dmesg) at boot if it provides any help (boot where usb stick is plugged, freeze, unplug, continues, stick plugged in again):

I was wondering if you have had any luck with this. I have a linksys WUSB54g and am seeing very similar things. I can boot just fine with the device plugged in, but modprobe ndiswrapper will start a loop along the same lines as:
If I modprobe -r ehci_hcd it will break the cycle and once in a while, even bring the device up. The only time that has worked was booting, modprobe -r ehci_hcd, modprobe ndiswrapper and then modprobe ehci_hcd again. This has only worked once or twice, however. The motherboard is an ASUS P4R8L (in a pundit-r) , which I've read has some problems, which may be causing all of this. Anyway just seeing if we can pick up any steam on this.

Unfortunately not. I haven't had time to get into the problem for a while (around two weeks).

I tried DriverLoader also. With it I can boot almost without problem but it does not work propely. Stick tries to fetch IP from server and server even replies to it but for some reason the response does not get through. I've asked help from Linuxant but problem is not solved yet.

The HTPC where I'm planning to use the stick is attached to TV so it's not easy to debug

I think I've found a bit of a pattern, if I go
modprobe -r ehci_hcd
modprobe ndiswrapper
modprobe ehci-hcd
modprobe -r ehci-hcd

The usb port that has my wireless adapter seems to hang around (which it normally will not after ehci is onloaded), even though ehci-hcd is not loaded, and then iwconfig shows my home network just fine. Don't know much more than this, or even why its happening. Just hope it helps get to an end...
