Hi Rebecca, We didn't check it in QEMU. Is QEMU report standard USB RNDIS protocol?
We only test it in physical device. Below is device lists. USB RNDIS: AST2500 : BMC report the RNDIS device USB NCM: DisplayLink HIS USB3.0 Portable Dock(DisplayLink (UK) Ltd.) Vendor ID: 0x17E9 Product ID: 0x4301 USB ECM: DM9621(Davicom Semiconductor, Inc.) Vendor ID: 0x0A46 Product ID: 0x1269 Thanks, Richard -----Original Message----- From: Rebecca Cran <rebe...@quicinc.com> Sent: 2022年9月6日 11:05 PM To: devel@edk2.groups.io; RichardHo [何明忠] <richar...@ami.com> Cc: Andrew Fish <af...@apple.com>; Leif Lindholm <quic_llind...@quicinc.com>; Michael D Kinney <michael.d.kin...@intel.com>; Michael Kubacki <michael.kuba...@microsoft.com>; Zhiguang Liu <zhiguang....@intel.com>; Liming Gao <gaolim...@byosoft.com.cn>; TonyLo [羅金松] <ton...@ami.com> Subject: [EXTERNAL] Re: [edk2-devel] [PATCH] UsbNetworkPkg: add USB network devices support **CAUTION: The e-mail below is from an external source.

Can't find image information. !!!! On Arm, I don't get a crash but no network interface gets created. I've checked the QEMU RNDIS interface is working: if I boot to Linux I can get an IP address and communicate with the outside world. -- Rebecca Cran On 9/1/22 23:24, RichardHo [何明忠] via groups.io wrote: > UsbNetworkPkg provides network functions for USB ACM, USB NCM, and USB > RNDIS network device. > > Signed-off-by: Richard Ho <richar...@ami.com> > Cc: Andrew Fish <af...@apple.com> > Cc: Leif Lindholm <quic_llind...@quicinc.com> > Cc: Michael D Kinney <michael.d.kin...@intel.com> > Cc: Michael Kubacki <michael.kuba...@microsoft.com> > Cc: Zhiguang Liu <zhiguang....@intel.com> > Cc: Liming Gao <gaolim...@byosoft.com.cn> > Reviewed-by: Tony Lo <ton...@ami.com> > --- > UsbNetworkPkg/Config/UsbNetworkPkg.inc.dsc | 9 + > .../Config/UsbNetworkPkgComponentsDxe.inc.dsc | 20 + > .../Config/UsbNetworkPkgComponentsDxe.inc.fdf | 20 + > .../Config/UsbNetworkPkgDefines.inc.dsc | 23 + > .../Include/Protocol/UsbEthernetProtocol.h | 872 +++++++++ > UsbNetworkPkg/NetworkCommon/ComponentName.c | 264 +++ > UsbNetworkPkg/NetworkCommon/DriverBinding.c | 583 ++++++ > UsbNetworkPkg/NetworkCommon/DriverBinding.h | 263 +++ > UsbNetworkPkg/NetworkCommon/NetworkCommon.inf | 43 + > UsbNetworkPkg/NetworkCommon/PxeFunction.c | 1734 +++++++++++++++++ > UsbNetworkPkg/ReadMe.md | 65 + > UsbNetworkPkg/ReleaseNotes.md | 11 + > UsbNetworkPkg/UsbCdcEcm/ComponentName.c | 170 ++ > UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.c | 504 +++++ > UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.h | 211 ++ > UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.inf | 41 + > UsbNetworkPkg/UsbCdcEcm/UsbEcmFunction.c | 861 ++++++++ > UsbNetworkPkg/UsbCdcNcm/ComponentName.c | 170 ++ > UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.c | 508 +++++ > UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.h | 245 +++ > UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.inf | 41 + > UsbNetworkPkg/UsbCdcNcm/UsbNcmFunction.c | 946 +++++++++ > UsbNetworkPkg/UsbNetworkPkg.dec | 32 + > UsbNetworkPkg/UsbRndis/ComponentName.c | 172 ++ > UsbNetworkPkg/UsbRndis/UsbRndis.c | 848 ++++++++ > UsbNetworkPkg/UsbRndis/UsbRndis.h | 569 ++++++ > UsbNetworkPkg/UsbRndis/UsbRndis.inf | 41 + > UsbNetworkPkg/UsbRndis/UsbRndisFunction.c | 1587 +++++++++++++++ > 28 files changed, 10853 insertions(+) > create mode 100644 UsbNetworkPkg/Config/UsbNetworkPkg.inc.dsc > create mode 100644 UsbNetworkPkg/Config/UsbNetworkPkgComponentsDxe.inc.dsc > create mode 100644 UsbNetworkPkg/Config/UsbNetworkPkgComponentsDxe.inc.fdf > create mode 100644 UsbNetworkPkg/Config/UsbNetworkPkgDefines.inc.dsc > create mode 100644 UsbNetworkPkg/Include/Protocol/UsbEthernetProtocol.h > create mode 100644 UsbNetworkPkg/NetworkCommon/ComponentName.c > create mode 100644 UsbNetworkPkg/NetworkCommon/DriverBinding.c > create mode 100644 UsbNetworkPkg/NetworkCommon/DriverBinding.h > create mode 100644 UsbNetworkPkg/NetworkCommon/NetworkCommon.inf > create mode 100644 UsbNetworkPkg/NetworkCommon/PxeFunction.c > create mode 100644 UsbNetworkPkg/ReadMe.md > create mode 100644 UsbNetworkPkg/ReleaseNotes.md > create mode 100644 UsbNetworkPkg/UsbCdcEcm/ComponentName.c > create mode 100644 UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.c > create mode 100644 UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.h > create mode 100644 UsbNetworkPkg/UsbCdcEcm/UsbCdcEcm.inf > create mode 100644 UsbNetworkPkg/UsbCdcEcm/UsbEcmFunction.c > create mode 100644 UsbNetworkPkg/UsbCdcNcm/ComponentName.c > create mode 100644 UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.c > create mode 100644 UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.h > create mode 100644 UsbNetworkPkg/UsbCdcNcm/UsbCdcNcm.inf > create mode 100644 UsbNetworkPkg/UsbCdcNcm/UsbNcmFunction.c > create mode 100644 UsbNetworkPkg/UsbNetworkPkg.dec > create mode 100644 UsbNetworkPkg/UsbRndis/ComponentName.c > create mode 100644 UsbNetworkPkg/UsbRndis/UsbRndis.c > create mode 100644 UsbNetworkPkg/UsbRndis/UsbRndis.h > create mode 100644 UsbNetworkPkg/UsbRndis/UsbRndis.inf > create mode 100644 UsbNetworkPkg/UsbRndis/UsbRndisFunction.c -The information contained in this message may be confidential and proprietary to American Megatrends (AMI).
