Subject: [ath9k-devel] ath9k_htc compatibility issue with virtualbox
Date: Thu, 01 Mar 2012 23:56:33 +0800	[thread overview]
Message-ID: <4F4F9C31.6070006@gmail.com> (raw)

Hi everyone,

I read from Internet and archive of this mail list that TP-Link WN821Nv3 
(using Atheros AR7010+AR9287) can't work. And that mail suggest this 
issue related to virtualbox being used. I have come across the same problem.

Tested the device on Debian without using virtualbox, and it works fine. 
Tested the device on Debian using virtualbox, got the following in 
/var/log/syslog

Mar  1 23:45:47 gene-d-laptop kernel: [   98.212097] usb 2-2: USB

Mar  1 23:45:53 gene-d-laptop kernel: [  104.605694] ath9k_htc: probe of

There are also several reports on the internet.

In some cases, due to company policy, I can't use linux without 
virtualization.

Does any one know how this can be solved? Or any work around? Is this a 
bug in Virtualbox USB or in ath9k_htc?

Thank you.
