Hi Alan, I swapped the driver, so usb_device_supports_lpm() always returns "0". No change. Bandwidth for a Class 10 SSD, but not for a mouse or keyboard. There is a new message that I've not seen before, hub_port_status failed (err = -71) === EPROTO $ lsusb -t /: Bus 02.Port 1: Dev 1,

[PATCH v3 4/6] usb: core: add power sequence handling for USB devices

Some hard-wired USB devices need to do power sequence to let the device work normally, the typical power sequence like: enable USB PHY clock, toggle reset pin, etc. But current Linux USB driver lacks of such code to do it, it may cause some hard-wired USB devices works abnormal or can't be

[PATCH v3 0/6] power: add power sequence library

Hi all, This is a follow-up for my last power sequence framework patch set [1]. According to Rob Herring and Ulf Hansson's comments[2], I use a generic power sequence library for parsing the power sequence elements on DT, and implement generic power sequence on library. The host driver can
