usbip

USB/IP for Windows

• This project aims to support both a USB/IP server and a client on Windows platform.

Build

Notes

• Build is tested on Windows 10 x64 and the projects are configured for this target by default.
• x86/x64 platforms should be supported. However, we don't have an x86 setup for testing at the moment.
• For Windows 7 users, change usbip_stub and usbip_vhci projects' Target OS version to Windows 7.
  • Right-click on the Project > Properties > Driver Settings > Target OS version > Windows 7
  • The recent tag version which supports is v0.1.0. All versions after v0.1.0 do not support Windows 7 or 8 because usbip-win started to use kernel libraries of Windows 10.

Build Tools

• Visual Studio 2019 Community (v142)
  • Build with VS 2017 (v141) is also possible if Platform Toolset in Setting is configured to v141.
• Windows SDK 10.0.18362.0 (recommended)
  • VS 2019 (v142): requires >= 10.0.18xxx
  • VS 2017 (v141): requires >= 10.0.17xxx
• Windows Driver Kit Windows 10, version 1903 (10.0.18362)
  • WDK 10.0.17134 (1803), 10.0.17763 (1809) and 10.0.18346 are also tested.

Build Process

• Open usbip_win.sln
• If VS 2017 is used, SDK version for userspace projects (usbip, usbip_common, usbipd, stubctl) should be adjusted.
• Set certificate driver signing for usbip_stub and usbip_vhci projects
  • Right-click on the Project > Properties > Driver Signing > Test Certificate
  • Browse to driver/usbip_test.pfx (password: usbip)
• Build solution or desired project
• All output files are created under {Debug,Release}/{x64,x86} folder.

Install

Windows USB/IP server

• Prepare a Linux machine as a USB/IP client or Windows usbip-win VHCI client (tested on Ubuntu 16.04 with kernel 4.15.0-29 - USB/IP kernel module crash was observed on some other versions)
  • # modprobe vhci-hcd
• Install USB/IP test certificate
  • Install driver/usbip_test.pfx (password: usbip)
  • Certificate should be installed into
  • "Trusted Root Certification Authority" in "Local Computer" (not current user) and
  • "Trusted Publishers" in "Local Computer" (not current user)
• Enable test signing
  • > bcdedit.exe /set TESTSIGNING ON
  • reboot the system to apply
• Copy usbip.exe, usbipd.exe, usb.ids, usbip_stub.sys, usbip_stub.inx into a folder in target machine
  • You can find usbip.exe, usbipd.exe, usbip_stub.sys in the output folder after build or on release page.
  • userspace/usb.ids
  • driver/stub/usbip_stub.inx

• Find USB Device ID

  • You can get id from usbip listing
  • > usbip.exe list -l

  • Bus id is always 1. So output from usbip.exe listing is shown as:

    usbip.exe list -l
    - busid 1-59 (045e:00cb)
    Microsoft Corp. : Basic Optical Mouse v2.0 (045e:00cb)
    - busid 1-30 (80ee:0021)
    VirtualBox : USB Tablet (80ee:0021)
    

• Bind USB device to usbip stub

  • The next command replaces the existing function driver with usbip stub driver
  • This should be executed using administrator privilege
  • usbip_stub.inx and usbip_stub.sys files should be in the same folder as usbip.exe
  • > usbip.exe bind -b 1-59

• Run usbipd.exe

  • > usbipd.exe -d -4
  • TCP port 3240 should be allowed by firewall

• Attach USB/IP device on Linux machine

  • # usbip attach -r <usbip server ip> -b 1-59

Windows USB/IP client

• Currently, there are 2 versions for a VHCI driver with different installation procedures:
  • vhci(wdm): original version, implemented via WDM (Windows Driver Model);
  • vhci(ude): newly developed version to fully support USB applications and implemented via UDE (USB Device Emulation) which is MS provided USB virtualization framework over KMDF (Kernel-Model Driver Framework).
• Prepare a Linux machine as a USB/IP server or Windows usbip-win stub server - (tested on Ubuntu 16.04 (kernel 4.15.0-29), 18.04, 20.04)
  • # modprobe usbip-host
  • You can use virtual usbip-vstub as a stub server
• Run usbipd on a USB/IP server (Linux)
  • # usbipd -4 -d
• Install USB/IP test certificate
  • Install driver/usbip_test.pfx (password: usbip)
  • Certificate should be installed into
  • "Trusted Root Certification Authority" in "Local Computer" (not current user) and
  • "Trusted Publishers" in "Local Computer" (not current user)
• Enable test signing
  • > bcdedit.exe /set TESTSIGNING ON
  • reboot the system to apply
• Copy VHCI driver files into a folder in target machine
  • If you're testing vhci(ude), copy usbip.exe, usbip_vhci_ude.sys, usbip_vhci_ude.inf, usbip_vhci_ude.cat into a folder in target machine;
  • If you're testing vhci(wdm), copy usbip.exe, usbip_vhci.sys, usbip_vhci.inf, usbip_root.inf, usbip_vhci.cat into a folder in target machine;
  • You can find all files in output folder after build or on release page.
• Install USB/IP VHCI driver
  • You can install using usbip.exe or manually
  • Using usbip.exe install command
  • Run PowerShell or CMD as an Administrator
  • PS> usbip.exe install
  • The previous command will install a UDE driver or a WDM driver depending on the available files
    • (UDE version first)
  • PS> usbip.exe install -u if UDE driver only
  • PS> usbip.exe install -w if WDM driver only
  • Manual Installation for vhci(ude)
  • Run PowerShell or CMD as an Administrator
  • PS> pnputil /add-driver usbip_vhci_ude.inf
  • Start Device manager
  • Choose "Add Legacy Hardware" from the "Action" menu.
  • Select "Install the hardware that I manually select from the list".
  • Click "Next".
  • Click "Have Disk", click "Browse", choose the copied folder, and click "OK".
  • Click on the "usbip-win VHCI(ude)", and then click "Next".
  • Click Finish at "Completing the Add/Remove Hardware Wizard".
    
  • Manual Installation for vhci(wdm)
  • Run PowerShell or CMD as an Administrator
  • PS> pnputil /add-driver usbip_vhci.inf
  • Start Device manager
  • Choose "Add Legacy Hardware" from the "Action" menu.
  • Select "Install the hardware that I manually select from the list".
  • Click "Next".
  • Click "Have Disk", click "Browse", choose the copied folder, and click "OK".
  • Click on the "USB/IP VHCI Root", and then click "Next".
  • Click Finish at "Completing the Add/Remove Hardware Wizard".
• Attach a remote USB device
  • PS> usbip.exe attach -r <usbip server ip> -b 2-2
• Uninstall driver
  • PS> usbip.exe uninstall
• Disable test signing
  • > bcdedit.exe /set TESTSIGNING OFF
  • reboot the system to apply

Reporting Bugs

• usbip-win is not yet ready for production use. We could find the problems with detailed logs.

How to get Windows kernel log for vhci(wdm)

• Set registry key to enable a debug filter

  • usbip-win uses DbgPrintEx API for kernel logging.
  • save following as .reg file and run or manually insert the registry key

  • reboot the system to apply

    Windows Registry Editor Version 5.00
    
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Debug Print Filter]
    "IHVDRIVER"=dword:ffffffff
    

• Run a debugging log viewer program before you test.

  • DebugView is a good tool to view the logs.

• If your testing machine suffer from BSOD (Blue Screen of Death), you should get it via remote debugging.

  • WinDbg on virtual machines would be good to get logs.

How to get Windows kernel log for vhci(ude)

• A new vhci(ude) implementation uses WPP SW tracing instead of DbgPrintEx.
  • DebugView.exe cannot catch a VHCI debug message
  • TraceView.exe is a good utility for a new approach, which is included in WDK.
• usbip_vhci_ude.pdb file is required to add a trace provider easily.
• Create a new session log in TraceView.exe
  • Choose PDB file radio button in \"Provider Control GUID Setup\" popup dialog
  • Specify usbip_vhci_ude.pdb as a PDB file
• You can send real-time trace messages to WinDbg by modifying in \"Advanced Log Session Options\".
• If your testing machine suffer from BSOD (Blue Screen of Death), you should get it via remote debugging.
  • WinDbg on virtual machines would be good to get logs

How to get usbip forwarder log

• usbip-win transmits usbip packets via a userland forwarder.
  • forwarder log is the best to look into usbip packet internals.
• edit usbip_forward.c to define DEBUG_PDU at the head of the file
• compile usbip.exe or usbipd.exe
• debug_pdu.log is created at the path where an executable runs.
  

How to get linux kernel log

• Sometimes Linux kernel log is required

  # dmesg --follow | tee kernel_log.txt
