Subject: Odroid C4: dwc2_hsotg_start_req: ep1 is stalled
Date: Thu, 20 May 2021 15:35:26 +0300	[thread overview]
Message-ID: <CAJs94EbV6+C81NggHtnJGZ8aoeW12POhv4zi0RTawuDcf+ybFA@mail.gmail.com> (raw)

Hi,

I am running upstream Linux 5.12.3 on an Odroid C4 board and see lots
of the following lines in dmesg while using the gadget mass storage
driver. I suppose that this can indicate some issue in the dwc2
driver.
