Subject: testusb: epipe errors on test 9 and 10
Date: Thu, 27 Nov 2025 09:06:24 +0100 [thread overview]
Message-ID: <cbb3bbc1-e8c1-450b-a38f-7b3f4cda6006@kernel-space.org> (raw)
Hi all,
looking for some help on testusb tool tests 9,10 always failing with
-EPIPE, kind of ep stall. Peripheral side has g_zero loaded.
Devices under test are custom boards, have same qualcomm 8 cores cpu, and
kernel is android 5.4. Involved drivers in both devices are xhci and dwc3.
Anyway, connection under tests is 2.0 microusb connector on both side.
/dev/bus/usb/001/007 test 9 --> 5 (I/O error)
/dev/bus/usb/001/007 test 10 --> 32 (Broken pipe)
usbmon shows for both cases some EPIPE:
