[Qemu-discuss] usb passthrough with Echelon U10 Network Interface

[Peter Münster]

Hi,

When trying to attach my Echelon U10 interface to my Win-XP qemu guest
system (the host is GNU/Linux x86-64), then unfortunately the guest
system freezes when loading the driver.

Here the messages on the host:

kernel: [163161.025239] usb 6-2: new full-speed USB device number 5 using

How could I get the usb passthrough working please?

My qemu version: 1.5.0

There is no such problem with vmplayer, but for various reasons I prefer qemu...

TIA for any help,
