VirtualBox PUEL 3.0.12 and SMC EZ connnect (zd1211rw)


Ok, I figured I would set up a virtual machine to play around with some of my wireless stuff. I have the usb adapter mentioned in the title and have some wierd stuff happening when I try to use it. In the virtual machine I have a fresh Slack64 13 install and no other packages added (except the guest additions). I have usb enabled with
Code:
none             /proc/bus/usb    usbfs       devgid=83,devmode=664 0  0
in /etc/fstab on the host machine. When I try to bring up the wlan0 in the virtual machine with ifconfig wlan0 up, I get
Code:
SIOCSIFFLAGS: Connection timed out
I can bring it up just fine in my host machine. It seems it has something to do with being able to load the firmware into the device. After I enable it in the virtual machine, I also get
Code:
zd1211rw 1-1:1.0: phy2
usb 1-1: firmware: requesting zd1211/zd1211b_ub
usb 1-1: firmware: requesting zd1211/zd1211b_uphr
usb 1-1: firmware: requesting zd1211/zd1211b_ub
usb 1-1: firmware: requesting zd1211/zd1211b_uphr
usb 1-1: USB control request for firmware upload failed. Error number -110
usb 1-1: Could not upload firmware code uph. Error number -110
zd1211rw 1-1:1.0: couldn't load firmware. Error number -110
in dmesg. Does anyone know if there is something else I need to do regarding usb? Is this a bug with VBox?


edit: Just noticed that VirtualBox 3.1.2 is out. Tried it on there and got the same results.

OK, might be a silly question but did you connect your USB via the USB Devices to your running VM?

Do you have the zd1211-firmware package installed on host and guest machines?

I have the same card by the way, and it's my favorite wireless nic so far, of course I've only ever used cheap ones.

@ Kenichi Kato: Yes, I connected it via the usb devices. That's when I get the dmesg errors.

@ vociz: Yes, it is installed. It is a fresh Slack64 13.0 (full) install. It works fine in the host machine also running Slack64 13.0.

edit: Just thought of something. Could it be that the host os is loading the firmware when the device is plugged in, and that is keeping the guest from loading it and keeping it from working? I guess I'll try to blacklist the module(s) for it on the host os. I'll give it a shot when I get home.

Update: I put
Code:
# This is for the smc ezconnect
blacklist zd1211rw
blacklist mac80211
blacklist cfg80211
in /etc/modprobe.d/blacklist.conf. I unplugged the adapter, modprobe -r'd the modules in question, then plugged it back in. The host system is not doing anything whatsoever with the adapter. Fired up my Slack64 13 vm, same results as before. So, it looks like it's not a matter of the host os loading the firmware into the device.

edit: Seems this is a Linux only thing. I fired up my XP vm, and the smc adapter worked. Kernel bug?
