Question wlan-ng (prism2) driver unable to detect DWL-520 card


OK, so I have a D-Link DWL-520 (Revision E) PCI wireless card. I was able to sucessfully load the driver (version 0.2.1-pre17) on my Redhat 9 installation. The driver loads on startup just fine but when attempting to find the device fails. I have read that boards that are not PCI 2.2 compliant may not work with this card, so I verified that mine has 2.2 PCI slots (which it does).

I thought initially that this may simply be an IRQ conflict or something similar however:

/proc/pci reveils the following about the device:

Bus 0, device 10, function 0:
Network controller: Harris Semiconductor Prism 2.5 Wavelan chipset (rev 1).
IRQ 9.
Master Capable. Latency=64.
Prefetchable 32 bit memory at 0xdddff000 [0xdddfffff].

Which means that the device must get an IRQ. There aren't any other devices attempting to use this IRQ either.

When attempting to load the driver dmesg reveils the following error:

prism2pci_init: prism2_pci.o: 0.2.1-pre17 Loaded
prism2pci_init: dev_info is: prism2_pci
PCI: Found IRQ 9 for device 00:0a.0
prism2: Cannot reserve PCI memory region
prism2pci_init: prism2_pci: No devices found, driver not installed.

I wanted to try to running insmod with the memory region and IRQ specified, however the only parameter I could find that the module will understand is irqlist= and frankly, it looks like the driver is able to find the IRQ of the device just fine and fails reserving a PCI memory region (whatever exactly that entails).

I am really not sure what I am doing wrong in this situation. Any help would be greatly appreciated, and if you live in the Twin Cities I'll even buy you lunch :-)

Thanks,

Reid

Reserved PCI memory region,

Either your kernel is compiled funny or, more likely, the driver is.

Wait... hmm, is this RH9? You mentioned it used to be... if its a newer distro hotplugging is on and the orinoco_pci module was loaded instead. It works better, usually, and "iwconfig" will configure it, unlike the wlan-ng modules.

What's the output of /sbin/lsmod

And what's the "dmesg" from the top down.

Also, how did you install these guys? hand compile, RPM?

Cheers,

Finegan

Yeah, its Redhat 9. I compiled the module myself against my current (2.4.20-28.9 Redhat built) kernel, and then added an alias in my modules.conf file.

The output lsmod is this:

The prism2 module is actually the p80211 module in this list.

A full output of dmesg gives this (its a bit long):
