So another question :-) Is it legal to break down a bulk (or ISO) IN request into packets that are *smaller* than the Max EP size ?
For example, I have a max EP size of 512 bytes and the gadget gives me an SG list where that's broken up into two segments (for example 2x256 bytes). Now, I'm still trying to confirm with the vendor what happens here, but I *suspect* that if I create 2 descriptors, the HW will break it down into 2 packets smaller than the max EP size on the wire. I do have vague memories of seeing "client" drivers in the past with make assumptions that some "replies" are fully contained in a single packet, so I'm tempted to say that this won't work, and thus should bounce such packets through a linear buffer but I'd like confirmation. Cheers, Ben. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
