Hi Heiko,
This patchserie adds the new config option CONFIG_DFU_FULLSPEED.
Is there any special reason to support Full Speed (12 Mbit/sec - USB 1.1) and not rely solely on the High Speed (USB 2.0) as we do now?
If this is enabled DFU uses fullspeed only. This is used on the siemens boards.
Is there any DFU problem with the mentioned Siemens board, that we must use USB 1.1?
I'd also appreciate more verbose rationale for this patch series - why this change is needed? What is the expected improvement?
Thanks in advance.
