https://bugzilla.kernel.org/show_bug.cgi?id=217862 Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |stern@xxxxxxxxxxxxxxxxxxx --- Comment #11 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- It's hard to tell exactly what's happening. There are several different odd things going on. In the first test, the device seems to alternate between saying that the media is present and that it isn't present. No way to tell why it's doing this. The oops in the second test results from the fact that the alauda_ensure_map_for_zone() routine doesn't check the return value from its call to alauda_read_map(). That's bad programming. But the reason the call failed was because the command transferred by alauda_get_redu_data() wasn't accepted by the device. Instead the command timed out and the driver had to cancel it and reset the device. The same thing happened with the command transferred by alauda_reset_media() in the first test. I can't tell if the problem is that the command isn't being sent properly or that the device isn't working properly. Can you collect a USB trace on the Windows system (with Wireshark or something similar)? If it shows the same command being sent and accepted by the device, it will mean there's something wrong with the way the commands are transferred on the Linux system. -- You may reply to this email to add a comment.
