Hi I have started playing around with a board based on the DragonBoard 820c and I cannot manage to get the USB2 working as host. If I connect a mouse, before I start the board I can see how the system powers up the port (vbus) and enumerates the device, just to kill it a couple of seconds later. If I try to connect anything to the port after the board has been started, I get absolutely no message on dmesg about the event, also no irqs on the hcd, only on the gpios related to the cable detection. Any ideas of what can be wrong/how to proceed? Thanks [ 6.153511] dwc3 read:0xc144 0x120c93b [ 6.157267] dwc3 read:0xc148 0x27012412 [ 6.161088] dwc3 read:0xc14c 0x4108084 [ 6.164818] dwc3 read:0xc150 0x47822004 [ 6.168640] dwc3 read:0xc154 0x4202088 [ 6.172369] dwc3 read:0xc158 0x7870020 [ 6.176204] dwc3 read:0xc15c 0x0 [ 6.179923] dwc3 read:0xc600 0x47a [ 6.183463] dwc3 read:0xc120 0x5533270a [ 6.186476] dwc3 write:0xc128 0x40e0f [ 6.190446] phy phy-7412000.phy.4: qusb2_phy_init(): Initializing QUSB2 phy [ 6.194349] qusb2: setbits: offset 0xb4 val 0x23 [ 6.200865] qusb2: conf: offset 0x80 val 0xf8 [ 6.205697] qusb2: conf: offset 0x84 val 0xb3 [ 6.209948] qusb2: conf: offset 0x88 val 0x83 [ 6.214287] qusb2: conf: offset 0x8c val 0xc0 [ 6.218628] qusb2: conf: offset 0x8 val 0x30 [ 6.222968] qusb2: conf: offset 0xc val 0x79 [ 6.227308] qusb2: conf: offset 0x10 val 0x21 [ 6.231562] qusb2: conf: offset 0x9c val 0x14 [ 6.235815] qusb2: conf: offset 0x1c val 0x9f [ 6.240155] qusb2: conf: offset 0x18 val 0x0 [ 6.244504] qusb2: setbits: offset 0x84 val 0xb0 [ 6.248840] qusb2: clrbits: offset 0xb4 val 0x1 [ 6.253613] qusb2: pll_test: offset 0x4 val 0x80 [ 6.257792] dwc3 read:0xc2c0 0x10c0002 [ 6.262519] dwc3 write:0xc2c0 0x10e0002 [ 6.266076] dwc3 read:0xc200 0x2500 [ 6.269811] Disabling power management [ 6.273280] dwc3 write:0xc200 0x2400 [ 6.277099] dwc3 read:0xc110 0x102000 [ 6.280833] dwc3 write:0xc110 0x102000 [ 6.284396] phy phy-7412000.phy.4: qusb2_phy_poweron(): Powering-on QUSB2 phy [ 6.288078] regulator: /usr/src/kernel/drivers/regulator/qcom_smd-regulator.c:60 id 24 type 1634690156 [ 6.295531] dwc3 write:0xc400 0xff05b000 [ 6.304448] dwc3 write:0xc404 0x0 [ 6.308526] dwc3 write:0xc408 0x1000 [ 6.311735] dwc3 write:0xc40c 0x0 [ 6.315382] dwc3 read:0xc11c 0xc0002 [ 6.318584] dwc3 write:0xc11c 0xc0002 [ 6.322241] dwc3 read:0xc110 0x102000 [ 6.325797] dwc3 write:0xc110 0x101000 [ 6.329990] xhci-hcd xhci-hcd.0.auto: xHCI Host Controller [ 6.333134] xhci-hcd xhci-hcd.0.auto: new USB bus registered, assigned bus number 1 [ 6.338585] xhci-hcd xhci-hcd.0.auto: xHCI capability registers at ffff00000d408000: [ 6.346119] xhci-hcd xhci-hcd.0.auto: CAPLENGTH AND HCIVERSION 0x1000020: [ 6.350898] extcon gpio: ID 0x0 VBUS 0x1 (0xffff8000ba02e2a0) [ 6.350900] extcon: extcon_set_state_sync \xc3\xaed:2 state:1 [ 6.366517] xhci-hcd xhci-hcd.0.auto: CAPLENGTH: 0x20 [ 6.371548] xhci-hcd xhci-hcd.0.auto: HCIVERSION: 0x100 [ 6.376761] xhci-hcd xhci-hcd.0.auto: HCSPARAMS 1: 0x1000140 [ 6.381793] xhci-hcd xhci-hcd.0.auto: Max device slots: 64 [ 6.387693] xhci-hcd xhci-hcd.0.auto: Max interrupters: 1 [ 6.393335] xhci-hcd xhci-hcd.0.auto: Max ports: 1 [ 6.398631] xhci-hcd xhci-hcd.0.auto: HCSPARAMS 2: 0xc0000f1 [ 6.403838] xhci-hcd xhci-hcd.0.auto: Isoc scheduling threshold: 1 [ 6.409482] xhci-hcd xhci-hcd.0.auto: Maximum allowed segments in event ring: 15 [ 6.415821] xhci-hcd xhci-hcd.0.auto: HCSPARAMS 3 0x7ff000a: [ 6.423206] xhci-hcd xhci-hcd.0.auto: Worst case U1 device exit latency: 10 [ 6.429014] xhci-hcd xhci-hcd.0.auto: Worst case U2 device exit latency: 2047 [ 6.436046] xhci-hcd xhci-hcd.0.auto: HCC PARAMS 0x220f665: [ 6.443162] xhci-hcd xhci-hcd.0.auto: HC generates 64 bit addresses [ 6.448717] xhci-hcd xhci-hcd.0.auto: HC hasn't Contiguous Frame ID Capability [ 6.455319] xhci-hcd xhci-hcd.0.auto: HC can generate Stopped - Short Package event [ 6.462781] xhci-hcd xhci-hcd.0.auto: FIXME: more HCCPARAMS debugging [ 6.470506] xhci-hcd xhci-hcd.0.auto: RTSOFF 0x440: [ 6.476929] xhci-hcd xhci-hcd.0.auto: xHCI operational registers at ffff00000d408020: [ 6.481793] xhci-hcd xhci-hcd.0.auto: USBCMD 0x0: [ 6.489776] xhci-hcd xhci-hcd.0.auto: HC is being stopped [ 6.494465] xhci-hcd xhci-hcd.0.auto: HC has finished hard reset [ 6.499846] xhci-hcd xhci-hcd.0.auto: Event Interrupts disabled [ 6.506096] xhci-hcd xhci-hcd.0.auto: Host System Error Interrupts disabled [ 6.512261] xhci-hcd xhci-hcd.0.auto: HC has finished light reset [ 6.519378] xhci-hcd xhci-hcd.0.auto: USBSTS 0x11: [ 6.525453] xhci-hcd xhci-hcd.0.auto: Event ring is empty [ 6.530315] xhci-hcd xhci-hcd.0.auto: No Host System Error [ 6.535783] xhci-hcd xhci-hcd.0.auto: HC is halted [ 6.541689] xhci-hcd xhci-hcd.0.auto: ffff00000d408420 port status reg = 0x20ae1 [ 6.546636] xhci-hcd xhci-hcd.0.auto: ffff00000d408424 port power reg = 0x0 [ 6.554019] xhci-hcd xhci-hcd.0.auto: ffff00000d408428 port link reg = 0x0 [ 6.560699] xhci-hcd xhci-hcd.0.auto: ffff00000d40842c port reserved reg = 0x0 [ 6.567645] xhci-hcd xhci-hcd.0.auto: // Halt the HC [ 6.574849] xhci-hcd xhci-hcd.0.auto: Resetting HCD [ 6.579967] xhci-hcd xhci-hcd.0.auto: // Reset the HC [ 6.584620] xhci-hcd xhci-hcd.0.auto: Wait for controller to be ready for doorbell rings [ 6.589780] xhci-hcd xhci-hcd.0.auto: Reset complete [ 6.597936] xhci-hcd xhci-hcd.0.auto: Enabling 64-bit DMA addresses.
