To be sure below issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced 8bc063641ceb #regzbot title usb: onboard-usb-hub breaks USB on RPi3 #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight. > Here is the relevant dmesg in error case: > > [ 0.078446] usbcore: registered new interface driver usbfs > [ 0.078516] usbcore: registered new interface driver hub > [ 0.078574] usbcore: registered new device driver usb > [ 0.078827] usb_phy_generic phy: supply vcc not found, using dummy > regulator > [ 0.078990] usb_phy_generic phy: dummy supplies not allowed for > exclusive requests > [ 2.897258] usbcore: registered new interface driver pegasus > [ 2.903161] usbcore: registered new interface driver asix > [ 2.908809] usbcore: registered new interface driver ax88179_178a > [ 2.915185] usbcore: registered new interface driver cdc_ether > [ 2.921281] usbcore: registered new interface driver smsc75xx > [ 2.927305] usbcore: registered new interface driver smsc95xx > [ 2.933298] usbcore: registered new interface driver net1080 > [ 2.939219] usbcore: registered new interface driver cdc_subset > [ 2.945407] usbcore: registered new interface driver zaurus > [ 2.951238] usbcore: registered new interface driver cdc_ncm > [ 3.030909] usbcore: registered new interface driver usb-storage > [ 3.178104] usbcore: registered new interface driver usbhid > [ 3.191022] usbhid: USB HID core driver > [ 3.981848] dwc2 3f980000.usb: supply vusb_d not found, using dummy > regulator > [ 3.992467] dwc2 3f980000.usb: supply vusb_a not found, using dummy > regulator > [ 4.053728] dwc2 3f980000.usb: DWC OTG Controller > [ 4.065343] dwc2 3f980000.usb: new USB bus registered, assigned bus > number 1 > [ 4.079415] dwc2 3f980000.usb: irq 66, io mem 0x3f980000 > [ 4.463447] usb 1-1: new high-speed USB device number 2 using dwc2 > [ 5.063444] usb 1-1.1: new high-speed USB device number 3 using dwc2 > [ 5.523440] usb 1-1.3: new low-speed USB device number 4 using dwc2 > [ 5.685546] input: HID 046a:0011 as > /devices/platform/soc/3f980000.usb/usb1/1-1/1-1.3/1-1.3:1.0/0003:046A:0011.0001/input/input0 > [ 5.763446] usb 1-1.1.2: new low-speed USB device number 5 using dwc2 > [ 5.777968] hid-generic 0003:046A:0011.0001: input: USB HID v1.11 > Keyboard [HID 046a:0011] on usb-3f980000.usb-1.3/input0 > [ 5.931991] input: PixArt Microsoft USB Optical Mouse as > /devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1/1-1.1.2/1-1.1.2:1.0/0003:045E:00CB.0002/input/input1 > [ 5.954668] hid-generic 0003:045E:00CB.0002: input: USB HID v1.11 > Mouse [PixArt Microsoft USB Optical Mouse] on usb-3f980000.usb-1.1.2/input0 > [ 6.263459] usb 1-1.1.1: new high-speed USB device number 6 using dwc2 > [ 14.828915] onboard-usb-hub 3f980000.usb:usb-port@1: supply vdd not > found, using dummy regulator > [ 14.829493] onboard-usb-hub 3f980000.usb:usb-port@1:usb-port@1: > supply vdd not found, using dummy regulator > [ 14.829729] usbcore: registered new device driver onboard-usb-hub > [ 14.829945] usb 1-1.1: USB disconnect, device number 3 > [ 14.829958] usb 1-1.1.1: USB disconnect, device number 6 > [ 14.830419] usb 1-1.1.2: USB disconnect, device number 5 > [ 14.854725] usb 1-1.3: USB disconnect, device number 4 > [ 14.896865] usbcore: registered new interface driver lan78xx > > Unfortunately i'm not that USB expert, so please tell me if you need > more information. > > >
