Hello, I'm trying to use this usb device : http://www.ingenico.com/en/products/payment_terminals/healthcare/twin30-plus_fm0cqjcy.html under windows guest, this usb device is mounting but not recognized it's seems to be a special usb device , that's using serial port ( create com3 ) under windows. some debug ( spicy, qemu libspice, linux spicy host ) version : qemu-kvm 1.1 rc3 , libspice from git, spicy 0.12
Some questions: 1) Have you tried using it without all the debugging enabled, debugging can slow things down considerably, and if this device is using an ftdi usb to serial conversion chip, then performance is going to matter, as that device has a buffer which needs to be emptied X times a second. 2) You say you're using qemu-kvm 1.1 rc3, do you have any additional patches on top of that? Unfortunately the chardev flowcontrol spice needs both for its agent and for usbredir is still not upstream :| usbredir will not be very reliable without chardev flowcontrol. Can you try using my qemu git tree here: http://cgit.freedesktop.org/~jwrdegoede/qemu/log/?h=qemu-kvm-1.0-usbredir Note that you need to use the qemu-kvm-1.0-usbredir branch, I'l try to rebase the chardev flowcontrol patches on top of 1.1-rc# one of these days.
