There is some confusion about when active commands should be destroyed. See http://marc.theaimsgroup.com/?l=linux-scsi&m=109647697621208&w=2 > Hi! > > I think you theory is right.

There is a problem with Genesys interface chips in 2.6.8.1 -- the correct workaround wasn't added until 2.6.9-rc1. If I had known before that your device used the Genesys chip I would have told you to do this earlier. Second, if that doesn't solve all your problems, try turning on the usb-storage verbose debugging option in the kernel configuration. That will add lots of extra information about failed commands, retries, and so on to your system log.
