my host operating system is ubuntu. I have an usb smartcard reader attached.
qemu version is 0.9.0.
qemu monitor shows me:
info usbhost
Device 2.2, speed 12Mb/s
Class 00: USB device 046d:c042, USB Gaming Mouse
Device 1.5, speed 12 Mb/s
Class 00: USB device 08e6:3437, USB SmratCard Reader
When I want to make this reader available to the client system using
usb_add host:08e6:3437
I get the
Could not add USB device 'host:08e6:3437
In the controlling terminal, where I started qemu, at the saem time I get:
usb_host: device already grabbed
Nevertheless,
info usb
show nothing.Sad
Any ideas would be appreciated.
Thanks
Norbert Wegener

stracing qemu showed, that the corresponding device file in /proc could not be opened. A pcscd already grepped it. After stopping pcscd the smartcard was available to the client.
