This m.2 dri= ve is a uas device, not usb_storage. The USB connected m.2 device does not suf= fer from the same problem as the internal USB connected SD card. It always surv= ives suspend/resume without disconnect/reconnect. Perhaps it was a mistake to have this extra device connected during my last usbmon run as it may make the trace more difficult to analyze. I will conti= nue to trace, without the external drive uas drive, until I again get a disconn= ect trace with the "k" quirk in place. If it would be useful to provide a reset trace without the external USB device plugged in, let me know. --=20 You may reply to this email to add a comment.
