AMSDK 08.00.00.00[edit]

1. Slowly plugging/removing the micro-A/B cable to/from the USB0 port causes kernel crash.

Solution: Apply Bin Liu's patch usb: dwc3: keep a copy of IDDIG status for DRD mode switch.

2. The driver does not drive the RESUME signal long enough which causes some hubs failed to resume.

Solution: Apply the following Felipe Balbi's patches, which will be available in mainline kernel v4.1-rc1.

a. usb: define a generic USB_RESUME_TIMEOUT macro.

b. usb: host: xhci: use new USB_RESUME_TIMEOUT.

c. usb: core: hub: use new USB_RESUME_TIMEOUT.
