With latest 'usb-next' kernel and supporting arch patches, when i use following test scenerio: Connect a USB 2.0 external hub to USB 2.0 port, and connect mice or keyboard enumeration and functionality is fine but once disconnecting the HID we get to see the error log: hid-generic 0003:04B3:3025.0002: can't reset device, s5p-ehci-1.3/input0, status -71 When i tried to enable CONFIG_USB_DEBUG, get the following log: hub 1-1:1.0: state 7 ports 7 chg 0000 evt 0008 hub 1-1:1.0: port 3, status 0301, change 0001, 1.5 Mb/s hub 1-1:1.0: debounce: port 3: total 100ms stable 100ms status 0x301 usb 1-1.3: new low-speed USB device number 5 using s5p-ehci usb 1-1.3: skipped 1 descriptor after interface usb 1-1.3: default language 0x0409 usb 1-1.3: udev 5, busnum 1, minor = 4 usb 1-1.3: New USB device found, idVendor=04b3, idProduct=3025 usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=0 usb 1-1.3: Product: USB NetVista Full Width Keyboard usb 1-1.3: Manufacturer: CHICONY usb 1-1.3: usb_probe_device usb 1-1.3: configuration #1 chosen from 1 choice usb 1-1.3: adding 1-1.3:1.0 (config #1, interface 0) usbhid 1-1.3:1.0: usb_probe_interface usbhid 1-1.3:1.0: usb_probe_interface - got id input: CHICONY USB NetVista Full Width Keyboard as /devices/s5p-ehci/usb1/1-1/1-1.3/1-1.3:1.0/input/input1 usb 1-1.3: link qh8-0e01/c193f140 start 2 [1/2 us] hid-generic 0003:04B3:3025.0002: input: USB HID v1.10 Keyboard [CHICONY USB NetVista Full Width Keyboard] on usb-s5p-ehci-1.3/input0 hub 1-1:1.0: state 7 ports 7 chg 0000 evt 0008 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 1 usb 1-1.3: unlink qh8-0e01/c193f140 start 2 [1/2 us] s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 1 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 2 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 3 hub 1-1:1.0: state 7 ports 7 chg 0000 evt 0008 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 4 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 5 hub 1-1:1.0: port 3, status 0100, change 0001, 12 Mb/s s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 6 usb 1-1.3: USB disconnect, device number 5 usb 1-1.3: unregistering device usb 1-1.3: unregistering interface 1-1.3:1.0 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 7 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 8 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 9 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 10 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 11 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 12 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 13 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 14 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 15 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 16 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 17 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 18 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 19 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 20 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 21 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 22 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 23 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 24 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 25 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 26 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 27 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 28 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 29 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 30 s5p-ehci s5p-ehci: detected XactErr len 0/8 retry 31 s5p-ehci s5p-ehci: devpath 1.3 ep0out 3strikes usb 1-1: clear tt buffer port 3, a5 ep0 t00080248 hid-generic 0003:04B3:3025.0002: can't reset device, s5p-ehci-1.3/input0, status -71 Similar log as you get on ehci-omap ;-) Sorry i might have missed some information to put here.
