[Qemu-devel] usb_host: only one interface supported

[Qemu-devel] usb_host: only one interface supported

[Christopher Friedt]

Hi everyone,

I'm trying to plug in a usb device (Motorola L2 phone, with micro usb 
connector).

When I try to add it using the qemu console,

usb_add host:22b8:4902

I get the response "usb_host: only one interface supported" in the 
standard output / error.

What does this mean exactly? Is there some way I could patch my source 
code to allow this to work?

I sort of got the impression that maybe the kernel had 'claimed' this 
device and therefore couldn't allow another app to address it directly. 
Is that the case?

I also tried removing / adding the cdc_acm module and running it that 
way as a serial console, but for me (running motorola software update) 
it seems not to work


Any suggestions?

I just applied the patch located in this thread:

http://lists.gnu.org/archive/html/qemu-devel/2007-06/msg00331.html

and it worked!

Thanks Arnaud
