FS#2808 - lantiq: xway: dwc2 - USB not working (ARV752DPW22 - EasyBox803a)

Device problem occurs on: ARV752DPW22 (EasyBox803a) tested.

Software versions of OpenWrt/LEDE release: since kernel 4.19 (OpenWrt trunk)

kernel 4.14 USB reset every time working

Steps to reproduce:

openWrt_trunk first boot	> hang!
30sec power supply disconnect	> no_hang
soft reboot			> no_hang
short power supply disconnect	> hang!
15sec power supply disconnect	> hang!
30sec power supply disconnect	> hang!
30sec power plug disconnect	> hang!
soft reboot			> hang!
60sec power plug disconnect	> hang!

?seems hardware related? (reproducible), 2 of 3 EasyBoxes have hang! bug / behave like


dwc2 1e101000.usb: dwc2_core_reset: HANG! Soft Reset timeout GRSTCTL GRSTCTL_CSFTRST
dwc2: probe of 1e101000.usb failed with error -16

full bootlog

tried fixes:

lantiq: 4.19: increase usb reset timeouts → set to: 1000000
