Hi,
I am seeing a problem with KVM where USB pass through is not working on
all devices.
ERROR: usb_linux_update_endp_table: Broken pipe
My "ActivKey" USB device is NOT passed through to my WinXP VM. Other USB
devics work fine.
Command
# qemu-kvm -m 512 -usb /vm/PCCOE_XP/pccoe_xp.img
open QEMU Monitor
info usbhost
usb_add host:xxxx:xxxx ("host:vendor_id:product_id")
or (Same for):
usb_add host:xxxx.xxxx ("host:bus.addr")
Following appears on terminal you ran the qemu-kvm command on:
husb: open device 6.6
husb: config #1 need -1
husb: 1 interfaces claimed for configuration 1
husb: grabbed usb device 6.6
usb_linux_update_endp_table: Broken pipe
Same with following options:
-no-kvm-irqchip
-no-kvm-pit
-no-kvm
