USB: core: add USB_QUIRK_NO_LPM for VIA Labs USB 2.0 hub
The VIA Labs, Inc. USB 2.0 hub controller (2109:2817),
found in a KVM switch, fails to enumerate high-power devices during
cold boot and system restart.
Applying the kernel parameter
usbcore.quirks=2109:2817:k
resolves the issue.
Enumeration failure log:
usb 1-1.2.3: device descriptor read/64, error -32
usb 1-1.2.3: Device not responding to setup address.
usb 1-1.2.3: device not accepting address 11, error -71
usb 1-1.2-port3: unable to enumerate USB device
Add USB_QUIRK_NO_LPM for this device.
