There seems to be two controller with vendor and device id as follows 8086:5aa8 8086:5aaa This is based on lspci output on Linux root@localhost:~# lspci -nn 00:00.0 Host bridge [0600]: Intel Corporation Device [8086:5af0] (rev 0b) 00:00.1 Signal processing controller [1180]: Intel Corporation Device [8086:5a8c] (rev 0b) 00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:5a84] (rev 0b) 00:0e.0 Audio device [0403]: Intel Corporation Device [8086:5a98] (rev 0b) 00:0f.0 Communication controller [0780]: Intel Corporation Device [8086:5a9a] (rev 0b) 00:11.0 Unclassified device [0050]: Intel Corporation Device [8086:5aa2] (rev 0b) 00:12.0 SATA controller [0106]: Intel Corporation Device [8086:5ae3] (rev 0b) 00:13.0 PCI bridge [0604]: Intel Corporation Device [8086:5ad8] (rev fb) 00:13.2 PCI bridge [0604]: Intel Corporation Device [8086:5ada] (rev fb) 00:13.3 PCI bridge [0604]: Intel Corporation Device [8086:5adb] (rev fb) 00:14.0 PCI bridge [0604]: Intel Corporation Device [8086:5ad6] (rev fb) 00:14.1 PCI bridge [0604]: Intel Corporation Device [8086:5ad7] (rev fb) 00:15.0 USB controller [0c03]: Intel Corporation Device [8086:5aa8] (rev 0b) 00:15.1 USB controller [0c03]: Intel Corporation Device [8086:5aaa] (rev 0b) 00:16.0 Signal processing controller [1180]: Intel Corporation Device [8086:5aac] (rev 0b) 00:16.1 Signal processing controller [1180]: Intel Corporation Device [8086:5aae] (rev 0b) 00:16.2 Signal processing controller [1180]: Intel Corporation Device [8086:5ab0] (rev 0b) 00:16.3 Signal processing controller [1180]: Intel Corporation Device [8086:5ab2] (rev 0b) 00:17.0 Signal processing controller [1180]: Intel Corporation Device [8086:5ab4] (rev 0b) 00:17.1 Signal processing controller [1180]: Intel Corporation Device [8086:5ab6] (rev 0b) 00:17.2 Signal processing controller [1180]: Intel Corporation Device [8086:5ab8] (rev 0b) 00:17.3 Signal processing controller [1180]: Intel Corporation Device [8086:5aba] (rev 0b) 00:18.0 Signal processing controller [1180]: Intel Corporation Device [8086:5abc] (rev 0b) 00:18.1 Signal processing controller [1180]: Intel Corporation Device [8086:5abe] (rev 0b) 00:18.2 Signal processing controller [1180]: Intel Corporation Device [8086:5ac0] (rev 0b) 00:18.3 Signal processing controller [1180]: Intel Corporation Device [8086:5aee] (rev 0b) 00:19.0 Signal processing controller [1180]: Intel Corporation Device [8086:5ac2] (rev 0b) 00:19.1 Signal processing controller [1180]: Intel Corporation Device [8086:5ac4] (rev 0b) 00:19.2 Signal processing controller [1180]: Intel Corporation Device [8086:5ac6] (rev 0b) 00:1b.0 SD Host controller [0805]: Intel Corporation Device [8086:5aca] (rev 0b) 00:1c.0 SD Host controller [0805]: Intel Corporation Device [8086:5acc] (rev 0b) 00:1e.0 SD Host controller [0805]: Intel Corporation Device [8086:5ad0] (rev 0b) 00:1f.0 ISA bridge [0601]: Intel Corporation Device [8086:5ae8] (rev 0b) 00:1f.1 SMBus [0c05]: Intel Corporation Device [8086:5ad4] (rev 0b) 02:00.0 Ethernet controller [0200]: Intel Corporation I210 Gigabit Network Connection [8086:157b] (rev 03) root@localhost:~# On Mon, Mar 6, 2017 at 3:13 PM, Bjørn Forsman <bjorn.fors...@gmail.com> wrote: > On 5 March 2017 at 18:22, Gailu Singh <gail...@gmail.com> wrote: > > git clone https://github.com/bjornfor/grub/ > > git checkout add-coreboot-xhci-driver-2nd-attempt-v2 > > ./autogen.sh > > ./configure --with-platform=coreboot > > make > > ------------------ > > > > BTW I changed the include directive in C files just to compile it and > would > > like to update that I included xhci module in grub.elf but there is no > sign > > of life on USB keyboard that is connected to USB3.0 on Intel Oxbohill CRB > > (Apollolake SOC). > > Just for reference, what is the PCI product and device ID of that > controller?
