are you referring to the `L' argument in messages1.ok-nohotplug: usb-storage: Command INQUIRY (6 bytes) usb-storage: 12 00 00 00 24 00 usb-storage: Bulk Command S 0x43425355 T 0x1 L 36 F 128 Trg 0 LUN 0 CL 6 versus messages2.ko-hotplug usb-storage: Command INQUIRY (6 bytes) usb-storage: 12 01 80 00 ff 00 usb-storage: Bulk Command S 0x43425355 T 0xd L 512 F 128 Trg 0 LUN 0 CL 6 ? > Your unusual_devs.h entry bypasses the issue by filtering out all INQUIRYs, > but that's not a good solution. The correct approach is to fix that hotplug > program. do you think this is a *bug* in the hotplug program, or is it "just" that i'm using one that doesn't fit to the kernel version? i take it that there must be some way for the hotplug script to determine which size to use, or at least some reason why to use 512 bytes, because i've got two other usb devices which work just fine with this script. if this ends up with "no, there is no way of determining that" and "usually devices are expected to tolerate whatever request comes in" then we're back at unusual_devs.h i'd say. > Can you provide information about which hotplug package you are using, or > where the block.agent program comes from? puuuh... it's the one from suse 9.1, no idea what version - i'll look it up. since suse uses to patch stuff on their own it may well be that they've included a broken one. cheers, tesche ps: the 2.6.0-test11 i mentioned as working has a suse 9.0 linux, so it may well have a different hotplug. ------------------------------------------------------- This SF.Net email sponsored by Black Hat Briefings & Training.
