USB support for smart card reader
When you attach a USB Card Reader from host to guest, but neither KVM-75 or KVM-76 works.
It of course connect the USB device, Windows XP detects it as a Cherry XX44 card reader, but it never detects when a smart card is inserted, so the application software cannot contact the smart card.
Using KVM-69 the smart card reader was fully functional.
CPU Model: Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz
KVM Version: KVM-75 / KVM-76
host kernel: 2.6.24-19 i386 (Ubuntu)
guest: Windows XP SP2
command line: kvm -hda wxp-b.img -net nic,model=virtio -net vde -m 256 -usb -usbdevice tablet -localtime -fda floppy -boot a -no-acpi
-usbdevice 'host:auto:*.*:046a:002d'
Using -no-kvm-irqchip: cannot read smart card
Using -no-kvm-pit: cannot read smart card
Using -no-kvm: cannot read smart card
Thank you very much

Max, looks like a usb regression. Any ideas?

Avi,
Thanx for the CC.
Gabriel,
Can you please send me the output of (on the host).
lsusb -v -d 046a:002d
Aslo if you could uncomment DEBUG in
kvm-userspace/qemu/usb-linux.c kvm-userspace/qemu/hw/usb-uhci.c
recompile and reproduce the scenario that'd be great.
You'd have to redirect qemu stdout & stderr to some file. The file will be huge so you'd want to either send it to me in private or put it on some web server or something.
Thanx
Max
