[Qemu-devel] USB-Mass-Storage and OpenBSD 4.7 problem

[Sebastian Schuetz <ssc@mistrust.net>]

Hello list,


I am trying to write to an usb image file using OpenBSD 4.7 as guest and 
a fresh "QEMU emulator version 0.12.90". While trying to access the 
device I got the following error messages:

Using some hardware USB-Stick (plugged into the host and forward it to 
the guest) works fine.
Anyone have a clue about it?  Please cc me in your replies because I am 
not subscribed to the list.
