It shows a bunch of reads with a few writes sprinkled among them. Then for no apparent reason, in the middle of a read the device was disconnected. Oddly, the bulk-IN URB that was in progress when the disconnect occurred did not complete immediately with an error. Instead it timed out after 30 seconds and was cancelled. Sarah, I thought you had fixed that? The drive reconnected, was re-enumerated, and a few seconds later disconnected again. No way to know the reason for these disconnects; they could be symptoms of a bad connection, hardware/firmware bugs, or even possibly a bug in xhci-hcd.
