I need the PCI vendor and device ID, which this version of lspci doesn't provide. I'm wondering if you have a Fresco Logic host that doesn't support MSI, even though it claims to (see the MSI field in the Capabilities lines): > 04:00.0 USB controller: Fresco Logic Device 1400 (rev 01) (prog-if 30 [XHCI]) > Subsystem: Device 1d5c:1000 > Physical Slot: 3 > Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ > Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- > Latency: 0, Cache Line Size: 64 bytes > Interrupt: pin A routed to IRQ 51 > Region 0: Memory at d4600000 (32-bit, non-prefetchable) [size=64K] > Capabilities: [50] Power Management version 3 > Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold-) > Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- > Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+ > Address: 00000000feeff00c Data: 41b1 > Capabilities: [80] Express (v1) Endpoint, MSI 00 > DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s <2us, L1 <32us > ExtTag- AttnBtn- AttnInd- PwrInd- RBE+ FLReset- > DevCtl: Report errors: Correctable- Non-Fatal- Fatal- Unsupported- > RlxdOrd+ ExtTag- PhantFunc- AuxPwr- NoSnoop+ > MaxPayload 128 bytes, MaxReadReq 512 bytes > DevSta: CorrErr- UncorrErr- FatalErr- UnsuppReq- AuxPwr- TransPend- > LnkCap: Port #0, Speed 2.5GT/s, Width x1, ASPM L0s L1, Latency L0 unlimited, L1 unlimited > ClockPM- Surprise- LLActRep- BwNot- > LnkCtl: ASPM Disabled; RCB 64 bytes Disabled- Retrain- CommClk+ > ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- > LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- > Kernel driver in use: xhci_hcd I think the dmesg shows that MSI is enabled for the host controller: > [ 1.988493] xhci_hcd 0000:04:00.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 > [ 1.988529] xhci_hcd 0000:04:00.0: setting latency timer to 64 > [ 1.988537] xhci_hcd 0000:04:00.0: xHCI Host Controller > [ 1.988604] xhci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 3 > [ 2.109283] xhci_hcd 0000:04:00.0: irq 19, io mem 0xd4600000 > [ 2.109363] xhci_hcd 0000:04:00.0: irq 51 for MSI/MSI-X But you're getting an unhandled IRQ, so this Fresco Logic may need a quirk like the previous generation to avoid MSI. I'll need the vendor and device ID from the lspci to generate a new patch for you to test. Do you know how to compile a custom kernel? If not, I'll send you some directions.
