I suppose it is the same story as SDM660. The SoC supports USB 3.0, but device manufacturers at that time didn't care for the sake of making them cheaper. So development kits had USB 3.0 (e.g. IFC6560), but the actual phones didn't. > > [ 22.986096] xhci-hcd xhci-hcd.1.auto: xHCI Host Controller > [ 22.986273] xhci-hcd xhci-hcd.1.auto: new USB bus registered, assigned bus number 1 > [ 22.990847] xhci-hcd xhci-hcd.1.auto: hcc params 0x0230f665 hci version 0x100 quirks 0x0000000002000010 > [ 22.998260] xhci-hcd xhci-hcd.1.auto: irq 57, io mem 0x07000000 > [ 23.007684] xhci-hcd xhci-hcd.1.auto: xHCI Host Controller > [ 23.013435] xhci-hcd xhci-hcd.1.auto: new USB bus registered, assigned bus number 2 > [ 23.019029] xhci-hcd xhci-hcd.1.auto: Host supports USB 3.0 SuperSpeed > [ 23.027696] hub 1-0:1.0: USB hub found > [ 23.033167] hub 1-0:1.0: 1 port detected > [ 23.037538] usb usb2: We don't know the algorithms for LPM for this host, disabling LPM. > [ 23.041853] hub 2-0:1.0: USB hub found > [ 23.049034] hub 2-0:1.0: 1 port detected > [ 23.120301] qcom,pmic-typec 200f000.spmi:pmic@2:typec@1500: vbus vsafe5v fail > [ 23.845537] usb 1-1: new high-speed USB device number 2 using xhci-hcd > [ 23.995466] usb-storage 1-1:1.0: USB Mass Storage device detected > [ 23.996166] scsi host0: usb-storage 1-1:1.0 > [ 25.022547] scsi 0:0:0:0: Direct-Access SanDisk Ultra 1.00 PQ: 0 ANSI: 6 > [ 25.023926] sd 0:0:0:0: [sda] 60062500 512-byte logical blocks: (30.8 GB/28.6 GiB) > [ 25.030873] sd 0:0:0:0: [sda] Write Protect is off > [ 25.037204] sd 0:0:0:0: [sda] Mode Sense: 43 00 00 00 > [ 25.042395] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA > [ 25.070314] sda: sda1 sda2 sda3 > [ 25.071050] sd 0:0:0:0: [sda] Attached SCSI removable disk > > > [ 31.347094] usb 1-1: USB disconnect, device number 2 > [ 31.364973] xhci-hcd xhci-hcd.1.auto: remove, state 4 > [ 31.365149] usb usb2: USB disconnect, device number 1 > [ 31.370427] xhci-hcd xhci-hcd.1.auto: USB bus 2 deregistered > [ 31.374236] xhci-hcd xhci-hcd.1.auto: remove, state 1 > [ 31.379906] usb usb1: USB disconnect, device number 1 > [ 31.475790] xhci-hcd xhci-hcd.1.auto: USB bus 1 deregistered > > Regards > Luca > > > > > > Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx> > > --- > > Changes in v2: > > -
