Subject: [Bug 220491] usb_storage connected SD card disconnects/reconnects on resume from suspend
Date: Wed, 03 Sep 2025 21:13:16 +0000 [thread overview]
Message-ID: <bug-220491-208809-t12UhO5L0Y@https.bugzilla.kernel.org/> (raw)

--- Comment #32 from Paul Ausbeck (paula@alumni.cse.ucsc.edu) ---
I thought it might be useful to gather data on what an actual physical
disconnect looks like during suspend/resume. I've run a test where I physically
remove the USB storage device while the machine is suspended and then trigger
resume. The trace data looks somewhat similar to the software simulated
disconnect but without any device communication attempts and without any
subsequent reconnect. The attached test data relates to the emb-qm77 MB.
