From: Stefan Mätje <Stefan.Maetje@xxxxxx> Hi Oliver, here is my patch to add support for CAN_CTRLMODE_CC_LEN8_DLC to the esd_usb2 driver. I have tested it with both supported devices the CAN-USB/2 and the CAN-USB/Micro. The patch is based on Marc's 'testing' branch of linux-can-next. I cloned it from here: https://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next.git/log/?h=testing Btw. is there a simple way to read out the supported control modes of the device (perhaps an ioctl())? The libsocketcan (at least the version 0.0.10) that I have here on my system does only support to get/set the current control mode and not the supported control modes. Best regards, Stefan PS: I cloned the wording for the patch subject and comment shameless from your patch for the other device drivers.
