Thanks for all your help!
Looks like it's LPM related again. To confirm, try this:
Disable LPM with this property "snps,usb2-gadget-lpm-disable"
(Note that it's not the same as "snps,dis_enblslpm_quirk")
Make sure that your testing kernel has this patch [1]
475e8be53d04 ("usb: dwc3: gadget: Check for disabled LPM quirk")
Thinh, Ferry, I'm a bit lost in this thread. Can you summarize what
patches I have to apply on top of v5.12-rc8 to mitigate issues,
mentioned in this thread?
(Sounds to me there are like ~5 patches floating around)
I have 3 on top usb-next (-rc7)
usb: dwc3: core: Do core softreset when switch mode
usb: dwc3: gadget: START_TRANSFER command needs to be executed while the
device is on "ON" state
usb: gadget: increase BESL baseline to 6
See here: https://github.com/htot/linux/commits/eds-acpi-5.12-rc7
I'll try to find time to test on my side.
