Sebastien: Thanks for the info. I just tried Linux 3.13.0-0.rc3.git5.1.fc21.i686 (from Fedora rawhide) and I still get the same error messages and USB still doesn't work. I saw a post about Atom Z3740D (Bay Trail-T) in a Dell Venue 8 Pro, and his USB works OK (but seems to use the xhci_hcd driver : [ 1.842164] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 1.842326] ehci-pci: EHCI PCI platform driver [ 1.842470] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver [ 1.842617] ohci-pci: OHCI PCI platform driver [ 1.843140] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 1.843363] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 1 [ 1.843964] xhci_hcd 0000:00:14.0: cache line size of 64 is not supported [ 1.844006] xhci_hcd 0000:00:14.0: irq 103 for MSI/MSI-X [ 1.844507] usb usb1: Product: xHCI Host Controller [ 1.844627] usb usb1: Manufacturer: Linux 3.13.0-0.rc2.git0.1.1.fc20.i686 xhci_hcd [ 1.846595] xhci_hcd 0000:00:14.0: xHCI Host Controller [ 1.846816] xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 2 [ 1.847423] usb usb2: Product: xHCI Host Controller [ 1.847555] usb usb2: Manufacturer: Linux 3.13.0-0.rc2.git0.1.1.fc20.i686 xhci_hcd [ 3.152500] usb 1-2: new high-speed USB device number 2 using xhci_hcd [ 3.456530] usb 1-2.1: new full-speed USB device number 3 using xhci_hcd [ 3.659527] usb 1-2.3: new low-speed USB device number 4 using xhci_hcd [ 3.870523] usb 1-2.4: new high-speed USB device number 5 using xhci_hcd Whereas my Gateway LT41P uses ehci & ohci : [ 65.497196] pci 0000:00:1d.0: EHCI: BIOS handoff failed (BIOS bug?) 01010001 [ 67.083013] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 67.087660] ehci-pci: EHCI PCI platform driver [ 67.100338] ehci-pci 0000:00:1d.0: EHCI Host Controller [ 67.107369] ehci-pci 0000:00:1d.0: new USB bus registered, assigned bus number 1 [ 67.112162] ehci-pci 0000:00:1d.0: debug port 2 [ 67.120972] ehci-pci 0000:00:1d.0: cache line size of 64 is not supported [ 67.121724] ehci-pci 0000:00:1d.0: irq 23, io mem 0x90705000 [ 67.131786] ehci-pci 0000:00:1d.0: USB 2.0 started, EHCI 1.00 [ 67.148118] usb usb1: Product: EHCI Host Controller [ 67.152623] usb usb1: Manufacturer: Linux 3.13.0-0.rc3.git5.1.fc21.i686 ehci_hcd [ 67.193364] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver [ 67.197795] ohci-pci: OHCI PCI platform driver [ 67.517839] usb 1-1: new high-speed USB device number 2 using ehci-pci [ 83.198813] usb 1-1: new high-speed USB device number 3 using ehci-pci [ 98.877636] usb 1-1: new high-speed USB device number 4 using ehci-pci [ 109.430911] usb 1-1: new high-speed USB device number 5 using ehci-pci A clue?
