[Qemu-devel] Asking about USB for QEMU

[Wojciech Zebrowski]

Hi

I try connect my host linux centos USB to Qemu for Xilinx Zynq solution.
I do following step :
1.Check usb vendor id , product id: lsusb




*Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubBus 002
Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hubBus 003 Device 001:
ID 1d6b:0002 Linux Foundation 2.0 root hubBus 004 Device 001: ID 1d6b:0003
Linux Foundation 3.0 root hub*

2. I start Qemu with switch :

*-usbdevice host:<VendorID>:<ProductID>*

*-usbdevice host:1d6b:0002*

 3. On Centos Host computer where Xilinx Qemu is started , i've error as :

*No 'PCI' bus found for device 'usb-ehci'*

What is incorrect with my command or system configuration ?

4. I check my motherboard bridge as following:

*qemu-system-x86_64 -device help |& grep usb.*hci*

*name "ich9-usb-ehci1", bus PCI name *

*"ich9-usb-ehci2", bus PCI name *

*"ich9-usb-uhci1", bus PCI name *

*"ich9-usb-uhci2", bus PCI name *

*"ich9-usb-uhci3", bus PCI name *

*"ich9-usb-uhci4", bus PCI name *

*"ich9-usb-uhci5", bus PCI name *

*"ich9-usb-uhci6", bus PCI name *

*"nec-usb-xhci", bus PCI name *

*"piix3-usb-uhci", bus PCI name *

*"piix4-usb-uhci", bus PCI name *

*"usb-ehci", bus PCI name *

*"vt82c686b-usb-uhci", bus PCI*


*Any advice for check ?*
