Hi Alexander,
Could you run "usbdump -d X.Y" at the same time to capture all the errors?
Looking especially for USB_ERR_TIMEOUT .
I have this:
xhci0@pci0:3:0:3: class=0x0c0330 rev=0x00 hdr=0x00 vendor=0x1022
device=0x15e0 subvendor=0x1849 subdevice=0xffff
vendor = 'Advanced Micro Devices, Inc. [AMD]'
device = 'Raven USB 3.1'
class = serial bus
subclass = USB
xhci0@pci0:0:20:0: class=0x0c0330 rev=0x21 hdr=0x00 vendor=0x8086
device=0x9d2f subvendor=0x8086 subdevice=0x9d2f
vendor = 'Intel Corporation'
device = 'Sunrise Point-LP USB 3.0 xHCI Controller'
class = serial bus
subclass = USB
