Hi all, I discovered some bug when I change kernel from 3.18.13 to 3.18.14. I have board with usb hub CY7C65632 on it. In .13 it works fine but in .14 it repeats this message: [ 19.170000] usb 2-3: new full-speed USB device number 56 using at91_ohci and devices connected to usb through hub doesn't appear at all. Here is dmesg | grep usb of .14: [ 3.220000] usbcore: registered new interface driver usbfs [ 3.220000] usbcore: registered new interface driver hub [ 3.220000] usbcore: registered new device driver usb [ 4.630000] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 4.640000] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.650000] usb usb1: Product: EHCI Host Controller [ 4.650000] usb usb1: Manufacturer: Linux 3.18.14_cpm9g25 ehci_hcd [ 4.660000] usb usb1: SerialNumber: 700000.ehci [ 4.770000] usb usb2: New USB device found, idVendor=1d6b, idProduct=0001 [ 4.780000] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.780000] usb usb2: Product: OHCI Host Controller [ 4.790000] usb usb2: Manufacturer: Linux 3.18.14_cpm9g25 ohci_hcd [ 4.800000] usb usb2: SerialNumber: at91 [ 4.840000] usbcore: registered new interface driver cdc_acm [ 4.850000] usbcore: registered new interface driver usb-storage [ 4.860000] atmel_usba_udc 500000.gadget: MMIO registers at 0xf803c000 mapped at c8888000 [ 4.870000] atmel_usba_udc 500000.gadget: FIFO at 0x00500000 mapped at c8900000 [ 4.890000] usb0: HOST MAC f2:a5:c3:38:f9:a3 [ 4.900000] usb0: MAC e2:fb:4b:4a:b7:97 [ 5.640000] usb 2-3: new full-speed USB device number 4 using at91_ohci [ 7.760000] usb 2-3: new full-speed USB device number 12 using at91_ohci [ 10.780000] usb 2-3: new full-speed USB device number 24 using at91_ohci [ 12.360000] usb 2-3: new full-speed USB device number 30 using at91_ohci [ 13.940000] usb 2-3: new full-speed USB device number 36 using at91_ohci [ 15.040000] usb 2-3: new full-speed USB device number 40 using at91_ohci [ 17.580000] usb 2-3: new full-speed USB device number 50 using at91_ohci ... and here of .13: [ 3.200000] usbcore: registered new interface driver usbfs [ 3.210000] usbcore: registered new interface driver hub [ 3.210000] usbcore: registered new device driver usb [ 4.630000] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 4.640000] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.650000] usb usb1: Product: EHCI Host Controller [ 4.650000] usb usb1: Manufacturer: Linux 3.18.13_cpm9g25 ehci_hcd [ 4.660000] usb usb1: SerialNumber: 700000.ehci [ 4.770000] usb usb2: New USB device found, idVendor=1d6b, idProduct=0001 [ 4.780000] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 4.780000] usb usb2: Product: OHCI Host Controller [ 4.790000] usb usb2: Manufacturer: Linux 3.18.13_cpm9g25 ohci_hcd [ 4.800000] usb usb2: SerialNumber: at91 [ 4.840000] usbcore: registered new interface driver cdc_acm [ 4.850000] usbcore: registered new interface driver usb-storage [ 4.860000] atmel_usba_udc 500000.gadget: MMIO registers at 0xf803c000 mapped at c8888000 [ 4.870000] atmel_usba_udc 500000.gadget: FIFO at 0x00500000 mapped at c8900000 [ 4.890000] usb0: HOST MAC de:5f:a8:09:26:b6 [ 4.900000] usb0: MAC 8a:a9:f8:36:9f:12 [ 5.200000] usb 2-3: new full-speed USB device number 2 using at91_ohci [ 5.410000] usb 2-3: not running at top speed; connect to a high speed hub [ 5.420000] usb 2-3: New USB device found, idVendor=04b4, idProduct=6570 [ 5.450000] usb 2-3: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [ 5.450000] usb 2-3: Product: USB2.0 Hub but in .14 other external noname hub on ehci works: [ 23.420000] usb 1-2: New USB device found, idVendor=04b4, idProduct=6560 [ 23.420000] usb 1-2: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 23.430000] hub 1-2:1.0: USB hub found [ 23.460000] hub 1-2:1.0: 4 ports detected Any idea?
