Hey Felipe, Last week or so, a change[1] in AOSP to adbd seemingly uncovered another issue with dwc3 gadget scatter-gather support on HiKey960. Interestingly it doesn't seem to affect the Dragonboard 845c, which uses the same dwc3 driver and has had its own issues in the past. The behavior is the same as we saw last time around with both devices. After booting the device, running "adb logcat -d" (or really any adb command that transfers more than a trivial amount of data) on the host will result in the adb output seeming to stall. Any further adb invocations to the device will hang indefinitely. I've captured trace events for before the change (works), after the change (broken), and after the change with the sg_enabled flag turned off (which works around the problem). Let me know if there is anything else useful for me to share. thanks -john [1] https://android.googlesource.com/platform/system/core/+/0871824de6c5b868f2a2e67c9b5673cb2181b4c6
