USB WiFi ath9k_htc device not initialized in Linux guest

[solamour]

I'm running VirtualBox 4.1.2 in Ubuntu 10.04 host with Gentoo Linux as the guest. I've been trying to use a USB WiFi device (Atheros chipset) in the guest OS, but so far no luck yet.

• When I put everything in the guest OS in a real machine (i.e. no VirtualBox guest), the USB WiFi device works OK.

• If the guest OS is Windows XP, I end up with an yellow exclamation in the Device Manager.

• If the guest OS is Linux, I'm getting the following kernel message.

[ 3.282211] ath9k_htc 1-1:1.0: usb_probe_interface [ 3.282222] ath9k_htc 1-1:1.0: usb_probe_interface - got id [ 3.772725] usb 1-1: ath9k_htc: Transferred FW: ar9271.fw, size: 51312 [ 4.772194] ath9k_htc 1-1:1.0: ath9k_htc: Target is unresponsive [ 4.772287] Failed to initialize the device [ 4.774250] ath9k_htc: probe of 1-1:1.0 failed with error -22 [ 4.775452] usbcore: registered new interface driver ath9k_htc

My guess is that the USB WiFi device itself and the setup in the Linux guest might not be an issue, because when I use a real machine, everything works perfectly. sol
