Description Radek Duda 2017-04-20 12:09:37 UTC
Description of problem:
USB 3.0 flash drive is not accessible in Windows guest

I installed here Renesas USB3.0 Host Controller Driver from http://www.dell.com/support/home/us/en/04/Drivers/DriversDetails?driverId=NGKKW since it was not installed automatically.

Installed also RHEV-Tools 4.1.5

How reproducible:

Steps to Reproduce:
1. Boot guest VM
2. Connect USB3.0 to client:
  Bus 003 Device 006: ID 0951:1666 Kingston Technology DataTraveler 100 G3/G4/SE9 G2
3. Connect to guest from remote-viewer
4. Redirect USB 3.0 device (flash drive or ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter used) from client to guest

Actual results:
Kingston Technology DataTraveler is removed from client, but not redirected to guest Win7.
ASIX AX88179 is redirected, but does not work with installed drivers.

Expected results:
USB 3.0 device is redirected from client to guest.

Additional info:
Win10 guest testing remark:
 No need to manually install driver for xhci controller (Renesas driver was installed automatically). In this case is USB disc redirected, but cannot be accessed (!). Tried also ASIX AX88179 USB 3.0 to Gigabit Ethernet Adapter, which works ok.

Hi, hachen

   Please help to reproduce the bug and handle the "qa_ack" tag.

USB3 in host/client:

    |__ Port 3: Dev 2, If 0, Class=Hub, Driver=hub/4p, 5000M

I connected to guest with remote-viewer and redirected USB 3. Device is redirected, but the content cannot be displayed. See attached screenshot.

spice-debug log while redirecting and loading USB3 drive in guest

Comment 6 ybendito 2017-05-07 17:31:41 UTC
Just for information: USB3.0 disk redirection worked without problem in following setup:
host: fedora 25, qemu-kvm 2.7.1-4, spice server 3.13
guest: win10 with nec-xhci
client: win10 + UsbDk 0.19 + spice client 5.0-256
disk: SanDisk Extreme USB 3.0
Worked when the disk is connected to usb3 hub on client and when connected to usb2 hub on client. Also usb redirection from host usb3 connector works without problems.

Comment 8 hachen 2017-05-11 08:42:57 UTC
I had a go with:

1. Start the guest through qemu cmd:
 /usr/libexec/qemu-kvm \
    -name 'avocado-vt-vm1'  \
    -sandbox off  \
    -machine pc  \
    -nodefaults  \
    -vga std  \
    -device pvpanic,ioport=0x505,id=id4FzGzg  \
    -device nec-usb-xhci,id=controller,bus=pci.0,addr=0x7 \
    -device virtio-scsi-pci,id=virtio_scsi_pci0,bus=pci.0,addr=0x3 \
    -drive id=drive_image1,if=none,snapshot=off,aio=native,cache=none,format=qcow2,file=/home/kvm_autotest_root/images/win2016-64-virtio-scsi.qcow2 \
    -device scsi-hd,id=image1,drive=drive_image1 \
    -device virtio-net-pci,mac=9a:4e:4f:50:51:52,id=idH8iBKj,vectors=4,netdev=iduyb7Wr,bus=pci.0,addr=0x4  \
    -netdev tap,id=iduyb7Wr \
    -m 8192  \
    -smp 4,cores=2,threads=1,sockets=2  \
    -cpu 'SandyBridge',+kvm_pv_unhalt,hv_spinlocks=0x1fff,hv_vapic,hv_time \
    -drive id=drive_cd1,if=none,snapshot=off,aio=native,cache=none,media=cdrom,file=/home/kvm_autotest_root/iso/windows/winutils.iso \
    -device scsi-cd,id=cd1,drive=drive_cd1 \
    -device usb-tablet,id=usb-tablet1,bus=controller.0,port=1  \
    -vnc :0  \
    -rtc base=localtime,clock=host,driftfix=slew  \
    -boot order=cdn,once=c,menu=off,strict=off \
    -enable-kvm \
    -monitor stdio \
    -qmp tcp:localhost:4444,server,nowait \
    -spice port=5931,disable-ticketing \
    -chardev spicevmc,name=usbredir,id=usbredirchardev1 \
    -device usb-redir,id=redir1,chardev=usbredirchardev1,bus=controller.0\

2. Connect the host
# remote-viewer spice://host_ip:5931

3. After win2016 guest, redirect the usb 3.0 device, and open win CMD:
C:\Users\Administrator> diskpart

DISKPART> list disk
The redirected USB 3.0 device was displayed.

Through both Disk Management and 'This PC', it can be checked.Pls check the attached.

The result is same for usb 2.0 flash drive.

usb 3.0 flash dirve can be found

You should be able to see the usb device through 'list disk' without doing anything.

However, you may need to format your usb flash dirve in order to have it displayed in 'This PC'

Comment 12 Ladi Prosek 2017-05-12 08:47:44 UTC
I can reproduce the issue with Radek's flash drive and have traced it down to this constant in hw/usb/hcd-xhci.c:

#define TRB_LINK_LIMIT  4

used in xhci_ring_fetch and xhci_ring_chain_length.

The first ~30 mass storage commands issued by Windows fit within the limit which is why the drive is recognized by Windows and appears in This PC. But then a 512 kiB bulk read comes in with 5 TRBs of type TR_LINK which is rejected by the QEMU xhci implementation and the communication stalls.

I'll read up some more on xhci to see if we can just increase the limit.

Comment 13 Gerd Hoffmann 2017-05-12 09:18:01 UTC
we had that with ohci too (see ab6b1105a2259c7072905887f71caa850ce63190).
just raising is fine.

Based on the comment 17, I test on the same machine and .qcow2 :

The Win2016 guest can boot up. The usb disk is accessible.
Bug verified.
